MCP Apps: Give the Model Data, Give the User a UI — Dustin Mihalik, Indeed

>> Uh hey everyone, I'm Dustin Macholic. Uh >> Uh hey everyone, I'm Dustin Macholic. Uh I work at Indeed. I work at Indeed. I work at Indeed. Uh we're the number one job site in the Uh we're the number one job site in the Uh we're the number one job site in the world. And I have to apologize for my world. And I have to apologize for my world. And I have to apologize for my voice. I'm recovering from a cold that I voice. I'm recovering from a cold that I voice. I'm recovering from a cold that I had last week. had last week. had last week. Um Um Um Yeah, so at Indeed, we build Yeah, so at Indeed, we build Yeah, so at Indeed, we build uh uh uh job search. And uh I also work on a team job search. And uh I also work on a team job search. And uh I also work on a team that does AI platform. And I do like AI that does AI platform. And I do like AI that does AI platform. And I do like AI guardrails and and gateways and guardrails and and gateways and guardrails and and gateways and compliance stuff. Uh occasionally uh my compliance stuff. Uh occasionally uh my compliance stuff. Uh occasionally uh my team gets cool projects to work on team gets cool projects to work on team gets cool projects to work on because we have relationships with the because we have relationships with the because we have relationships with the vendors. Uh MCP apps is one of those. vendors. Uh MCP apps is one of those. vendors. Uh MCP apps is one of those. And um And um And um MCP connectors. So, this is a little bit MCP connectors. So, this is a little bit MCP connectors. So, this is a little bit of like practical MCP apps. They gave a of like practical MCP apps. They gave a of like practical MCP apps. They gave a great introduction uh to MCP apps. This great introduction uh to MCP apps. This great introduction uh to MCP apps. This is a little bit of a lessons from the is a little bit of a lessons from the is a little bit of a lessons from the trenches, uh which is a little bit of trenches, uh which is a little bit of trenches, uh which is a little bit of like what did we learn in building MCP like what did we learn in building MCP like what did we learn in building MCP and MCP apps for Claude chat chat GPT and MCP apps for Claude chat chat GPT and MCP apps for Claude chat chat GPT and our own internal and our own internal and our own internal uh uh uh uh career scout, which is our uh agent uh career scout, which is our uh agent uh career scout, which is our uh agent that we have for job seekers.

that we have for job seekers. that we have for job seekers. So, this is the this is the chat-based So, this is the this is the chat-based So, this is the this is the chat-based interface. So, a lot of my examples are interface. So, a lot of my examples are interface. So, a lot of my examples are going to be job search. This will I have going to be job search. This will I have going to be job search. This will I have a lot of screenshots of job searches. a lot of screenshots of job searches. a lot of screenshots of job searches. Um So, this is this is a job search, Um So, this is this is a job search, Um So, this is this is a job search, which is basically uh you know, I'm which is basically uh you know, I'm which is basically uh you know, I'm looking for barista in Austin. And this looking for barista in Austin. And this looking for barista in Austin. And this is a text-based response. And this works is a text-based response. And this works is a text-based response. And this works pretty well. Uh as we kind of discussed, pretty well. Uh as we kind of discussed, pretty well. Uh as we kind of discussed, like there's no branding here. There's like there's no branding here. There's like there's no branding here. There's no Indeed branding. Uh you know, Claude no Indeed branding. Uh you know, Claude no Indeed branding. Uh you know, Claude decided to say these are some jobs in decided to say these are some jobs in decided to say these are some jobs in Austin. These are some jobs in some Austin. These are some jobs in some Austin. These are some jobs in some suburbs of Austin. That's cool. That's suburbs of Austin. That's cool. That's suburbs of Austin. That's cool. That's probably good for the user. There may be probably good for the user. There may be probably good for the user. There may be some limitations uh some limitations uh some limitations uh of like what we can do for branding or of like what we can do for branding or of like what we can do for branding or how we can uh how we can uh how we can uh you know, how we can control things. And you know, how we can control things. And you know, how we can control things. And you'd be actually be surprised uh unless you'd be actually be surprised uh unless you'd be actually be surprised uh unless you've tried to do this yourself that um you've tried to do this yourself that um you've tried to do this yourself that um it's really hard to get Claude or it's really hard to get Claude or it's really hard to get Claude or ChatGPT to link to things cuz they don't ChatGPT to link to things cuz they don't ChatGPT to link to things cuz they don't want you to leave their environment. It want you to leave their environment. It want you to leave their environment. It makes complete sense, but uh if you get makes complete sense, but uh if you get makes complete sense, but uh if you get back, here's five jobs that are back, here's five jobs that are back, here's five jobs that are somewhere on the internet uh without any somewhere on the internet uh without any somewhere on the internet uh without any links, that's a terrible user links, that's a terrible user links, that's a terrible user experience. Uh so it's it took us a experience. Uh so it's it took us a experience. Uh so it's it took us a ridiculous number of hours and evals to ridiculous number of hours and evals to ridiculous number of hours and evals to make sure that like Claude would make sure that like Claude would make sure that like Claude would consistently link to things.

consistently link to things. consistently link to things. So with MCP apps and with uh apps SDK, So with MCP apps and with uh apps SDK, So with MCP apps and with uh apps SDK, uh we could kind of control that. Uh we uh we could kind of control that. Uh we uh we could kind of control that. Uh we can decide can decide can decide uh you know, that we've got an apply uh you know, that we've got an apply uh you know, that we've got an apply button. We can decide what stuff is button. We can decide what stuff is button. We can decide what stuff is important that we want to highlight at important that we want to highlight at important that we want to highlight at the top. We can provide a link to view the top. We can provide a link to view the top. We can provide a link to view details details details um so that when you click it, you get uh um so that when you click it, you get uh um so that when you click it, you get uh a a pop-up, a a modal that has all the a a pop-up, a a modal that has all the a a pop-up, a a modal that has all the job details so you don't have to leave job details so you don't have to leave job details so you don't have to leave the environment. So it's it's a win-win the environment. So it's it's a win-win the environment. So it's it's a win-win uh for for both for both uh for both uh for for both for both uh for both uh for for both for both uh for both companies. companies. companies. So uh MCP apps is really good, but if So uh MCP apps is really good, but if So uh MCP apps is really good, but if you're thinking about hey, I want to you're thinking about hey, I want to you're thinking about hey, I want to build an MCP app or I want to take my build an MCP app or I want to take my build an MCP app or I want to take my website, I want to put it in ChatGPT or website, I want to put it in ChatGPT or website, I want to put it in ChatGPT or Claude, uh it's not quite just as easy Claude, uh it's not quite just as easy Claude, uh it's not quite just as easy as like dragging and dropping into a as like dragging and dropping into a as like dragging and dropping into a chat interface. Uh you really want to chat interface. Uh you really want to chat interface. Uh you really want to think about how you are representing the think about how you are representing the think about how you are representing the data, how you're making it available to data, how you're making it available to data, how you're making it available to the user. the user. the user. So if you do a very naive thing, So if you do a very naive thing, So if you do a very naive thing, uh which is you still call your existing uh which is you still call your existing uh which is you still call your existing APIs uh for loading data, um then it APIs uh for loading data, um then it APIs uh for loading data, um then it basically becomes a black box to the basically becomes a black box to the basically becomes a black box to the model, right? So you say, "Hey, I want model, right? So you say, "Hey, I want model, right? So you say, "Hey, I want to do something." The model says, "Cool, to do something." The model says, "Cool, to do something." The model says, "Cool, I'll call a tool."

I'll call a tool." I'll call a tool." The tool says, "Okay, I'm going to show The tool says, "Okay, I'm going to show The tool says, "Okay, I'm going to show some stuff, but the model has no idea some stuff, but the model has no idea some stuff, but the model has no idea what what you're displaying." So, what what you're displaying." So, what what you're displaying." So, there's all these like follow-up there's all these like follow-up there's all these like follow-up questions, like tell me about the first questions, like tell me about the first questions, like tell me about the first result, or please rank this list of result, or please rank this list of result, or please rank this list of companies. The model has no idea what companies. The model has no idea what companies. The model has no idea what data is being displayed. data is being displayed. data is being displayed. So, the very first rule So, the very first rule So, the very first rule uh for me uh for me uh for me uh building MCP apps, anything that you uh building MCP apps, anything that you uh building MCP apps, anything that you show to the user also needs to be show to the user also needs to be show to the user also needs to be provided as data to the model. I think provided as data to the model. I think provided as data to the model. I think this makes sense, but uh I've definitely this makes sense, but uh I've definitely this makes sense, but uh I've definitely seen some MCP apps where they just, you seen some MCP apps where they just, you seen some MCP apps where they just, you know, use it to inject some HTML on the know, use it to inject some HTML on the know, use it to inject some HTML on the page and then call some APIs, page and then call some APIs, page and then call some APIs, uh and that's that just makes a big uh and that's that just makes a big uh and that's that just makes a big black box for the model. So, this is black box for the model. So, this is black box for the model. So, this is really easy to do really easy to do really easy to do uh using MCP spec and the MCP app spec. uh using MCP spec and the MCP app spec. uh using MCP spec and the MCP app spec. Uh this structured content, this is what Uh this structured content, this is what Uh this structured content, this is what you would already be returning if you you would already be returning if you you would already be returning if you were doing just text-based MCP. Um and were doing just text-based MCP. Um and were doing just text-based MCP. Um and then this resource URI, that's points to then this resource URI, that's points to then this resource URI, that's points to where the HTML is. You need to return where the HTML is. You need to return where the HTML is. You need to return both of these, and you need to keep them both of these, and you need to keep them both of these, and you need to keep them in sync, right? If you add something new in sync, right? If you add something new in sync, right? If you add something new to the API, you make sure you add to the API, you make sure you add to the API, you make sure you add something add that same data something add that same data something add that same data uh back.

uh back. uh back. So, kind of the next step um that uh So, kind of the next step um that uh So, kind of the next step um that uh that once you do that, that once you do that, that once you do that, uh you'll find is that now you've uh you'll find is that now you've uh you'll find is that now you've provided data to the model, provided data to the model, provided data to the model, and you provided this black box that it and you provided this black box that it and you provided this black box that it has no idea about, it's still going to has no idea about, it's still going to has no idea about, it's still going to try and describe the it's still going to try and describe the it's still going to try and describe the it's still going to try and take the output and describe it try and take the output and describe it try and take the output and describe it as it normally would. So, you end up as it normally would. So, you end up as it normally would. So, you end up with like, "Here's your display." and with like, "Here's your display." and with like, "Here's your display." and then here's the model doing basically then here's the model doing basically then here's the model doing basically the same thing that it would normally the same thing that it would normally the same thing that it would normally do. Um so, what you need to do is you do. Um so, what you need to do is you do. Um so, what you need to do is you need to update your description in order need to update your description in order need to update your description in order to tell it that you're going to be to tell it that you're going to be to tell it that you're going to be displaying stuff in your MCP app. Uh displaying stuff in your MCP app. Uh displaying stuff in your MCP app. Uh that way you get this like nice, you that way you get this like nice, you that way you get this like nice, you know, here's a list of you know, here's know, here's a list of you know, here's know, here's a list of you know, here's a little summary of things, and you a little summary of things, and you a little summary of things, and you know, the results are are are showed know, the results are are are showed know, the results are are are showed above the links, rather than it trying above the links, rather than it trying above the links, rather than it trying to like do a whole text-based display. to like do a whole text-based display. to like do a whole text-based display. Um Um Um you'll end up with this a little bit of you'll end up with this a little bit of you'll end up with this a little bit of a battle between like what gets a battle between like what gets a battle between like what gets displayed in UI and what gets displayed displayed in UI and what gets displayed displayed in UI and what gets displayed by the model. You can try and steer that by the model. You can try and steer that by the model. You can try and steer that with descriptions. So, even something as with descriptions. So, even something as with descriptions. So, even something as simple as results were automatically simple as results were automatically simple as results were automatically displayed to the user as UI components displayed to the user as UI components displayed to the user as UI components at the top of your description, your at the top of your description, your at the top of your description, your tool description, tool description, tool description, uh that covers that covers quite a bit uh that covers that covers quite a bit uh that covers that covers quite a bit of the cases. Um of the cases. Um of the cases. Um So, that's one of the next things that So, that's one of the next things that So, that's one of the next things that you're going to want to do uh once you're going to want to do uh once you're going to want to do uh once you're providing both data and API you're providing both data and API you're providing both data and API access.

access. access. Uh the next thing is there's these Uh the next thing is there's these Uh the next thing is there's these interactable pieces, right? There's the interactable pieces, right? There's the interactable pieces, right? There's the apply button, there's a view details apply button, there's a view details apply button, there's a view details button, which pops up a big job button, which pops up a big job button, which pops up a big job description. description. description. Um this is the same case where, you Um this is the same case where, you Um this is the same case where, you know, as you interact with those, the know, as you interact with those, the know, as you interact with those, the model's not going to know necessarily model's not going to know necessarily model's not going to know necessarily what you're looking at. So, you click what you're looking at. So, you click what you're looking at. So, you click view details, you get a big modal that's view details, you get a big modal that's view details, you get a big modal that's here's everything about the job. here's everything about the job. here's everything about the job. There's once again a whole bunch of There's once again a whole bunch of There's once again a whole bunch of questions that the user could ask. questions that the user could ask. questions that the user could ask. Uh write a cover letter for this job, Uh write a cover letter for this job, Uh write a cover letter for this job, summarize this job description. It has summarize this job description. It has summarize this job description. It has no idea because you've loaded that data no idea because you've loaded that data no idea because you've loaded that data in either in via API or you loaded it in in either in via API or you loaded it in in either in via API or you loaded it in dynamically, dynamically, dynamically, uh you know, hit you return 10 jobs and uh you know, hit you return 10 jobs and uh you know, hit you return 10 jobs and user clicks on one, user clicks on one, user clicks on one, the model has no idea which one you the model has no idea which one you the model has no idea which one you clicked on. clicked on. clicked on. Uh so, any information about user Uh so, any information about user Uh so, any information about user interactions, you also need to provide interactions, you also need to provide interactions, you also need to provide to the model. to the model. to the model. And And And uh once again, MCP abstract has a pretty uh once again, MCP abstract has a pretty uh once again, MCP abstract has a pretty easy way to handle it. There's this easy way to handle it. There's this easy way to handle it. There's this update model context update model context update model context um method, which lets you pass in a um method, which lets you pass in a um method, which lets you pass in a string string string uh that is uh that is uh that is So, for MCP apps, there's a single So, for MCP apps, there's a single So, for MCP apps, there's a single string. Uh so, if you like want to track string. Uh so, if you like want to track string. Uh so, if you like want to track multiple events over time, you kind of multiple events over time, you kind of multiple events over time, you kind of have to append have to append have to append uh multiple things to the string, but uh multiple things to the string, but uh multiple things to the string, but this is this is this is an example from this is this is this is an example from this is this is this is an example from the MCP apps uh documentation where the MCP apps uh documentation where the MCP apps uh documentation where basically, you know, this is a shopping basically, you know, this is a shopping basically, you know, this is a shopping cart application and they add the total cart application and they add the total cart application and they add the total cost and all the items that are on the

cost and all the items that are on the cost and all the items that are on the shopping cart so the user can ask for shopping cart so the user can ask for shopping cart so the user can ask for uh you know, "Tell me information about uh you know, "Tell me information about uh you know, "Tell me information about the items that are in my shopping cart." the items that are in my shopping cart." the items that are in my shopping cart." >> [snorts] >> So, these >> So, these two things give you an app that like the two things give you an app that like the two things give you an app that like the model could kind of see what's going on. model could kind of see what's going on. model could kind of see what's going on. Um but it doesn't necessarily make a Um but it doesn't necessarily make a Um but it doesn't necessarily make a really good MCP app yet really good MCP app yet really good MCP app yet uh because it gives you it gives you uh because it gives you it gives you uh because it gives you it gives you some UI that looks like what you want, some UI that looks like what you want, some UI that looks like what you want, but but but the thing that I usually do, I don't the thing that I usually do, I don't the thing that I usually do, I don't give I don't give the I don't I don't give I don't give the I don't I don't give I don't give the I don't I don't give Claude give Claude give Claude uh my easy problems to solve. I give uh my easy problems to solve. I give uh my easy problems to solve. I give Claude my really hard problems to solve, Claude my really hard problems to solve, Claude my really hard problems to solve, right? Like if I just wanted to do one right? Like if I just wanted to do one right? Like if I just wanted to do one search, I would go to the web and do one search, I would go to the web and do one search, I would go to the web and do one search. I want to do a whole bunch of search. I want to do a whole bunch of search. I want to do a whole bunch of searches. Uh searches. Uh searches. Uh this is this is out of date cuz there's this is this is out of date cuz there's this is this is out of date cuz there's no Sonic 5 here yet, but uh this is no Sonic 5 here yet, but uh this is no Sonic 5 here yet, but uh this is screenshot from 2 days ago. screenshot from 2 days ago. screenshot from 2 days ago. Uh but yeah, so that So, like this job Uh but yeah, so that So, like this job Uh but yeah, so that So, like this job search is "Hey, I'm looking for this I'm search is "Hey, I'm looking for this I'm search is "Hey, I'm looking for this I'm looking for this title.

looking for this title. looking for this title. I'm willing to relocate, so I want to I'm willing to relocate, so I want to I'm willing to relocate, so I want to search across a whole bunch of different search across a whole bunch of different search across a whole bunch of different cities. cities. cities. Um you know, I'm looking for the highest Um you know, I'm looking for the highest Um you know, I'm looking for the highest paying option, so I want you to just paying option, so I want you to just paying option, so I want you to just cherry-pick a few out of there. There's cherry-pick a few out of there. There's cherry-pick a few out of there. There's some industries that I absolutely don't some industries that I absolutely don't some industries that I absolutely don't want to work in." want to work in." want to work in." Text-based MCP Text-based MCP Text-based MCP does really well. Like does really well. Like does really well. Like we all see this, right? Claude will do we all see this, right? Claude will do we all see this, right? Claude will do 10 different searches, 15 different 10 different searches, 15 different 10 different searches, 15 different searches. It'll filter, it'll pull out searches. It'll filter, it'll pull out searches. It'll filter, it'll pull out all the individual pieces, all the individual pieces, all the individual pieces, uh and then it gives you a nice table at uh and then it gives you a nice table at uh and then it gives you a nice table at the bottom, uh which is which is super the bottom, uh which is which is super the bottom, uh which is which is super nice. nice. nice. >> [snorts] >> [snorts] >> [snorts] >> But with the MCP app that we were just >> But with the MCP app that we were just >> But with the MCP app that we were just discussing, you know, we we said, "Hey, discussing, you know, we we said, "Hey, discussing, you know, we we said, "Hey, uh you know, my results are going to be uh you know, my results are going to be uh you know, my results are going to be displayed in this UI. Uh displayed in this UI. Uh displayed in this UI. Uh We know Claude Claude will call it once We know Claude Claude will call it once We know Claude Claude will call it once and then it'll be like, "Oh, I guess the and then it'll be like, "Oh, I guess the and then it'll be like, "Oh, I guess the results are already displayed. I'm not results are already displayed. I'm not results are already displayed. I'm not going to like do a deep dive, right?" going to like do a deep dive, right?" going to like do a deep dive, right?" Like it doesn't It's you as a user are Like it doesn't It's you as a user are Like it doesn't It's you as a user are not going to want 10 different carousels not going to want 10 different carousels not going to want 10 different carousels and Claude and Claude and Claude will also notice that like it's already will also notice that like it's already will also notice that like it's already been displaying some stuff and it won't been displaying some stuff and it won't been displaying some stuff and it won't call to show 10 different carousels.

call to show 10 different carousels. call to show 10 different carousels. Um Um Um and so what you really want to do, and and so what you really want to do, and and so what you really want to do, and this is rule three, this like supersedes this is rule three, this like supersedes this is rule three, this like supersedes all the other rules, all the other rules, all the other rules, uh which is basically you want to uh which is basically you want to uh which is basically you want to separate your data processing from your separate your data processing from your separate your data processing from your UI rendering. UI rendering. UI rendering. And this particular wording I stole uh And this particular wording I stole uh And this particular wording I stole uh from OpenAI uh from OpenAI uh >> [snorts] >> OpenAI >> OpenAI >> OpenAI uh uh uh Apps SDK documentation. There's a couple Apps SDK documentation. There's a couple Apps SDK documentation. There's a couple places where they say this. places where they say this. places where they say this. Um but basically they want to You want Um but basically they want to You want Um but basically they want to You want to separate your data processing from to separate your data processing from to separate your data processing from your UI rendering. So the job search your UI rendering. So the job search your UI rendering. So the job search that we had that we had that we had we're just going to have that be a we're just going to have that be a we're just going to have that be a standard text-based MCP application. standard text-based MCP application. standard text-based MCP application. Claude can call that as many times as it Claude can call that as many times as it Claude can call that as many times as it wants. And then we have a render tool wants. And then we have a render tool wants. And then we have a render tool that either that either that either you can pass you can pass you can pass you can have the model basically pass you can have the model basically pass you can have the model basically pass all the data that it wants to render in all the data that it wants to render in all the data that it wants to render in or you can do a reference uh to it. So or you can do a reference uh to it. So or you can do a reference uh to it. So in our particular case in our particular case in our particular case uh you know, we had search jobs. Now we uh you know, we had search jobs. Now we uh you know, we had search jobs. Now we have a search jobs that doesn't return have a search jobs that doesn't return have a search jobs that doesn't return any UI and we have a render jobs widget any UI and we have a render jobs widget any UI and we have a render jobs widget that takes a list of IDs.

that takes a list of IDs. that takes a list of IDs. Um and so that list of IDs Um and so that list of IDs Um and so that list of IDs uh uh uh can be, you know, Claude can do a can be, you know, Claude can do a can be, you know, Claude can do a search. It can get search. It can get search. It can get a hundred different jobs that it cares a hundred different jobs that it cares a hundred different jobs that it cares about. It can filter those. It can find about. It can filter those. It can find about. It can filter those. It can find five that it cares about and it can show five that it cares about and it can show five that it cares about and it can show those five to the user. those five to the user. those five to the user. Um now as you make these like render Um now as you make these like render Um now as you make these like render uh as you make these render calls, you uh as you make these render calls, you uh as you make these render calls, you need to update the descriptions to say need to update the descriptions to say need to update the descriptions to say like where did they get the data, what like where did they get the data, what like where did they get the data, what format the data should be. format the data should be. format the data should be. But it's a fairly easy fairly easy But it's a fairly easy fairly easy But it's a fairly easy fairly easy mechanism to update your tool mechanism to update your tool mechanism to update your tool description to say you need to always description to say you need to always description to say you need to always call one of these three tools first in call one of these three tools first in call one of these three tools first in order to get order to get order to get the data that you're going to be using the data that you're going to be using the data that you're going to be using for rendering. for rendering. for rendering. So, search jobs, this is a pretty good So, search jobs, this is a pretty good So, search jobs, this is a pretty good um um um It's a pretty good example It's a pretty good example It's a pretty good example of of how we where we want to split data of of how we where we want to split data of of how we where we want to split data from rendering. I think there's a ton of from rendering. I think there's a ton of from rendering. I think there's a ton of other like other like other like in most industries, you can kind of come in most industries, you can kind of come in most industries, you can kind of come up with like, "Hey, where do I want to up with like, "Hey, where do I want to up with like, "Hey, where do I want to you know, where do I want to split?"

you know, where do I want to split?" you know, where do I want to split?" Like I want to be I want Like I want to be I want Like I want to be I want the model to be able to explore this the model to be able to explore this the model to be able to explore this data and then I want it to turn around data and then I want it to turn around data and then I want it to turn around and choose to be able to render it. and choose to be able to render it. and choose to be able to render it. Right? Like there's there's examples of Right? Like there's there's examples of Right? Like there's there's examples of you know you know you know e-commerce, right? Like e-commerce, right? Like e-commerce, right? Like a bunch of e-commerce options. a bunch of e-commerce options. a bunch of e-commerce options. If you've got a map, you know, maybe you If you've got a map, you know, maybe you If you've got a map, you know, maybe you want to come up with like five different want to come up with like five different want to come up with like five different addresses and then you pass in addresses and then you pass in addresses and then you pass in addresses. addresses. addresses. The other thing that you can do is you The other thing that you can do is you The other thing that you can do is you can let the model be a lot more can let the model be a lot more can let the model be a lot more creative. Like one of the things that creative. Like one of the things that creative. Like one of the things that we've seen in some of this text-based we've seen in some of this text-based we've seen in some of this text-based stuff is that stuff is that stuff is that you know, the model will say like, "This you know, the model will say like, "This you know, the model will say like, "This is a is a is a >> [clears throat] >> [clears throat] >> [clears throat] >> This is a reason why I picked this one." >> This is a reason why I picked this one." >> This is a reason why I picked this one." Or "This is a reason why this is really Or "This is a reason why this is really Or "This is a reason why this is really good." good." good." And so, you know, potentially we can add And so, you know, potentially we can add And so, you know, potentially we can add something to the render jobs widget something to the render jobs widget something to the render jobs widget where you say give us an ID and a reason where you say give us an ID and a reason where you say give us an ID and a reason why you think that this is a good fit. why you think that this is a good fit. why you think that this is a good fit. Or give us an ID and highlight a section Or give us an ID and highlight a section Or give us an ID and highlight a section of the job description that is really of the job description that is really of the job description that is really good. Um, so you can get really creative good. Um, so you can get really creative good. Um, so you can get really creative with your render tools to be able to with your render tools to be able to with your render tools to be able to have to be able to give some extra have to be able to give some extra have to be able to give some extra character that the model can inject character that the model can inject character that the model can inject into those so that into those so that into those so that so that you've got a much better so that you've got a much better so that you've got a much better experience for the user.

experience for the user. experience for the user. So [snorts] the key takeaways So [snorts] the key takeaways So [snorts] the key takeaways right right right when building MCP apps, you want to when building MCP apps, you want to when building MCP apps, you want to focus on the data before you focus on focus on the data before you focus on focus on the data before you focus on the UI which sounds sounds opposite of the UI which sounds sounds opposite of the UI which sounds sounds opposite of you know how we were thinking about it you know how we were thinking about it you know how we were thinking about it of like hey there's all these there's of like hey there's all these there's of like hey there's all these there's these MCP apps like it's how I put UI these MCP apps like it's how I put UI these MCP apps like it's how I put UI into chat GPT. into chat GPT. into chat GPT. I think if you want to really have a I think if you want to really have a I think if you want to really have a good MCP apps experience, you need to good MCP apps experience, you need to good MCP apps experience, you need to you need to look at and see what data do you need to look at and see what data do you need to look at and see what data do I want to what data do I want to give to I want to what data do I want to give to I want to what data do I want to give to the model, what data do I want it to be the model, what data do I want it to be the model, what data do I want it to be able to do and then able to do and then able to do and then rendering is a side effect of of that or rendering is a side effect of of that or rendering is a side effect of of that or it's a result of the the model exploring it's a result of the the model exploring it's a result of the the model exploring the data. the data. the data. And then I think small composable tools, And then I think small composable tools, And then I think small composable tools, right? So right? So right? So uh uh uh basically, you know basically, you know basically, you know maybe there's like two or three maybe there's like two or three maybe there's like two or three different ways you can search for jobs. different ways you can search for jobs. different ways you can search for jobs. We could build two or three different We could build two or three different We could build two or three different search tools and then there's one render search tools and then there's one render search tools and then there's one render tool or maybe there's like maybe there's tool or maybe there's like maybe there's tool or maybe there's like maybe there's two render tools there's one that's two render tools there's one that's two render tools there's one that's render a list of jobs, one that's, you render a list of jobs, one that's, you render a list of jobs, one that's, you know, highlight one particular job. So know, highlight one particular job. So know, highlight one particular job. So you could build a bunch of much smaller you could build a bunch of much smaller you could build a bunch of much smaller tools. The descriptions can be fairly tools. The descriptions can be fairly tools. The descriptions can be fairly simple so you don't overload the model, simple so you don't overload the model, simple so you don't overload the model, but it gives the model flexibility about but it gives the model flexibility about but it gives the model flexibility about how it wants to explore the data and how how it wants to explore the data and how how it wants to explore the data and how it wants to render the tools.

it wants to render the tools. it wants to render the tools. So that's So that's So that's basically basically my talk. I'm a few basically basically my talk. I'm a few basically basically my talk. I'm a few minutes few minutes fast. minutes few minutes fast. minutes few minutes fast. But I don't have a booth that I'm going But I don't have a booth that I'm going But I don't have a booth that I'm going to hang out in, but I'll I'll hang out to hang out in, but I'll I'll hang out to hang out in, but I'll I'll hang out in the hall if anyone has any questions. in the hall if anyone has any questions. in the hall if anyone has any questions. And I am either my last name or my first And I am either my last name or my first And I am either my last name or my first initial last name on most social media initial last name on most social media initial last name on most social media platforms. platforms. platforms.
