Web Dev Challenge Hackathon: Build an App for Just You $500 cash prize for the winner Open September 9 – Submissions due September 22 at 11:59 PM PT
As developers, we all notice little routines in our lives that could be better with the right app — if only someone built it. With Postman MCP Servers and the AI Agent Builder, building custom apps for yourself is more possible than ever.
So here’s the challenge: build a MCP-powered app made just for you.
Maybe it’s an app that turns off your Wi-Fi at 8pm so you finally get some sleep. Or a chore schedule that perfectly fits your family. Or even a calendar that only tracks new releases in your favorite book series.
Make it practical. Make it silly. Whatever you build, make it personally valuable. Creative misinterpretations of the prompt are encouraged — the more fun you have, the better.
Requirements
Your app must use Postman as part of the build.
In this challenge, you’ll want to look into Postman’s suite of tools for designing and building MCP servers and agentic workflows:
MCP Servers - tons of available MCP servers that you can use
Generate an MCP Server - Postman has tools that allow you to generate your own MCP server from any public API
Postman AI Agent Builder - tools including LLM prompt testing, agent workflow designer, and tool generation
The Public API Network - this is a huge collection of public APIs that you can use as part of your build
Postman Notebooks - this makes it easy for others to understand your process, see your API calls, and try your project themselves
Contest open worldwide to participants 18+. By entering, you grant Postman the right to feature your submission on our website, blog, and social channels. Winners will be announced here and notified via Discourse DM.Privacy Policy | Postman
Do we have to use every Postman tool listed (MCP Servers, Agent Builder, Public API Network, Notebooks, etc.) to qualify, or is it acceptable to build our project with just one of them?
For the “publish” requirement, are we required to host our project in a specific place (e.g., a Postman-hosted space), or may we choose any public platform GitHub, Replit, Glitch, Netlify, as long as we share the link in the official Discourse thread?
No! You don’t have to use them all! The only requirement is to use a Postman Notebook as means to sharing your hackathon project. You can share links to the repo, collections (if any), MCP servers, or videos walk throughs of your demos.
For the “publish” requirement, are we required to host our project in a specific place?
Hosting can be done anywhere, we just need to be able to see the hackathon project and access it. If it’s in a private repo, we won’t be able to judge it, but of course we’ll message someone first letting them know.
Thank you for the question! The goal is to make this as simple as possible and lower the barrier of entry. Good luck, and happy hacking!
I believe that it’s currently for members only, so that those users have early access but as you can see from the other videos in the series, this will become public.
Crypto Purchasing Power Calculator
As a student who’s interested in cryptocurrency and trading, I often found myself staring at abstract numbers like “$67,000 for 1 Bitcoin” without truly understanding what that means in real life. How many cups of coffee could that buy? How many months of groceries? This app makes crypto values tangible and relatable. Live Demo & Resources

Built with MCP to solve my personal job search challenges. Features:
- Smart job matching (92% match for Postman roles!)
- Skill gap analysis
- Application tracking
- Interview prep
I built this to track opportunities and display the power of MCP and Postman, identify skills to learn, and prepare for interviews. The MCP server implements 5 tools that power the intelligent features. I am also taking this a step further and adding GA to the headers for tracking statistics and whatnot because I am nosey :)

I try to catch up with the news every morning. But I find it tedious because sorting news into one category based on topic is pretty stressful. And when I find these articles, they are so long that I don’t even want to read them completely.
That’s why I built the news summarizer MCP server. It fetches news based on a particular topic and then summarizes them, sparing me the time and stress of having to search and digest the news myself.
I made a Model Context Protocol (MCP) server that enables seamless Google Calendar integration with MCP-compatible clients like Postman and Claude Desktop.
I rely on Google Calendar every day to keep my life on track. Classes, assignment deadlines, meetings — everything ends up in my calendar. But switching between tabs or apps just to check my schedule or add a new event started to feel clunky and repetitive.
When Postman announced this challenge about building an app “just for you,” I knew exactly what I wanted: a custom MCP server that talks directly to Google Calendar so I can manage my day-to-day activities programmatically.
With this server I can:
List all my calendars and events without opening the Google Calendar UI.
Quickly add new events or reminders from anywhere.
And the real power comes when I connect it with Claude (or any LLM) . Now I can literally ask in natural language:
“Create a timetable for me for this Friday.”
“When am I free next week?”
“Add a hackathon deadline on 22nd at 11:59 PM.”
Claude calls my MCP server under the hood, checks my calendar, and answers me conversationally. Instead of adapting myself to the calendar app, I made the calendar adapt to me — all powered by Postman MCP tools, Google Calendar API, and AI.
This small tool makes my schedule lighter, faster and more personal.
That’s why I built it — to turn my calendar into an intelligent assistant rather than just a static list of events.
As a developer struggling with vaping addiction, I built QuitVaping as my personal health companion. This isn’t just another health app - it’s MY app/webApp, designed specifically for my triggers, my habits, and my journey to quit vaping. This is a deeply personal, MCP-powered web app that learns patterns and provides AI-driven interventions exactly when I need them.
I have used it and feel much better thus far. It makes a lot of sense.
As a student from India, I’ve always struggled with juggling dense study notes, deciphering handwritten diagrams quickly, and retaining info during long commutes without audio aids. Traditional tools felt clunky, so I built StudBud AI an MCP-powered study assistant that turns images into explanations using Gemini OCR and generates audio guides for any topic with ElevenLabs TTS. Leveraging Postman’s MCP Generator, I created a custom server to seamlessly integrate these APIs, making it agent-friendly for voice interactions and rapid prototyping (inspired by my recent voice assistant projects).
This project not only solved my study woes but also showcases how Postman tools can supercharge AI apps. Here’s everything you need:
Stop drowning in digital chaos. Start exploring your memories.
Like most people, I was losing important memories in the endless scroll of emails, photos, and calendar events. Instead of building another folder system, I created something revolutionary: Memory Palace - an automated 3D world that transforms your digital life into an explorable, spatial experience.
What Makes This Different
Zero-effort setup meets intelligent organization. Connect your Gmail and Calendar, and watch as your digital memories automatically materialize as interactive 3D objects in a personalized virtual space.
Revolutionary Features:
Fully Automated - No manual room creation or object placement required
AI-Powered Insights - Discover hidden patterns in your digital behavior
Real Data Integration - Your actual emails become explorable 3D objects
Real-Time Sync - New memories instantly appear in your palace
MCP Server Integration - 3 custom tools for intelligent memory processing
The Problem Solved
Before: Endless scrolling through Gmail threads, forgotten photos, lost meeting notes After: Spatial navigation where work emails appear as cubes in your “Professional Zone” and family photos float in your “Personal Gallery” - everything positioned based on context, date, and relationships.
Technical Innovation
Automated 3D Pipeline:
API Data → MCP Processing → Laravel Backend → Three.js Rendering
While traditional memory palace apps require hours of manual setup, Memory Palace builds itself from your data in seconds. Connect Gmail → Instant 3D world populated with your real memories → AI insights about your digital patterns.
Every time I plan a movie night, the hardest part isn’t snacks or the screen setup—it’s choosing what to watch ( and I know everyone struggles with this). I noticed my choices are often tied to my mood, and my mood is tied (a little too much) to the weather. Rain makes me want a slow drama. Sunny days call for an upbeat comedy. Cold evenings? Horror vibes.
So, I decided to automate this routine with Postman. Using the AI Agent Builder, I built an agent that pulls live weather data of my place and combines it with a movie TMDB API from the Public API Network. The agent maps the current weather to a movie genre, then serves up a recommendation instantly.
This tiny project turned out to be surprisingly useful. Instead of scrolling endlessly, I just type in my city, and the AI agent acts as my weather-aware movie buddy.
I love studying math every day with a cup of coffee, but finding great articles on math is time-consuming. I built MyDailyMath.xyz — an app that uses Gemini AI and a Tavily MCP server (generated via Postman) to find high-quality math articles on any topic. Now, I can enjoy fresh math insights every morning without searching.
How it works?
when I give the AI a math topic, and Gemini AI uses the Tavily MCP server (generated via Postman) to search deeply for relevant articles. It finds the best content so you can enjoy reading without spending time searching.
I’m excited to share my submission for the “Build an App for Just You” challenge - PersonalAI Research Assistant that’s completely transformed how I handle my daily research.
As someone who’s constantly trying to keep up with the latest in AI and tech, I found myself drowning in research papers every morning. I’d spend 2-3 hours jumping between CrossRef, arXiv, and Google Scholar, then copying abstracts into ChatGPT just to understand what they were about. It was honestly exhausting and I was missing so many important papers.
So I built this MCP server that integrates directly with Claude Desktop. Now I can just ask: “Hey, find me some recent papers on transformer architectures and give me the key takeaways” - and boom, I get exactly what I need in minutes instead of hours.
What I Built With Postman
I used Postman’s MCP Generator to create the server foundation, integrated the CrossRef API from their Public API Network for academic search, and connected OpenAI’s API for intelligent summarization.
I used to think I was eating fine, but drinks and snacks kept pushing me past my sugar goal before noon. I built QuitSugar to give me one number and one small nudge—no guilt, just awareness.
What I used
Nutrition MCP (OpenFoodFacts) and Journal MCP (Supabase RPCs)
Postman Agent Builder for the tiny coaching workflow
Why it matters
This already made me pause before grabbing another “innocent” snack. A clear number and one kind sentence were enough to change my choices—exactly what I needed.
I created Garaa — a period tracker and supplies manager that syncs with Notion using the Notion API. It helps users track cycles, manage inventory of essentials, and stay organized — all in one place.
Here’s what I used to build it:
Postman MCP Servers: for building the backend workflows.
Postman AI Agent Builder: to automate reminders, notifications, and smart tracking.
Public API Network: leveraged Notion API to sync data in real-time.
Postman Notebooks: fully documented API calls and workflows, so anyone can test or extend the app.
Description:
This project connects WhatsApp (via Meta Business Suite) with Spotify, powered by an Agentic AI. The AI chats with me on WhatsApp, understands my mood or plans, and instantly creates dynamic playlists tailored to what I’m about to do. I can manage playlists, songs, and Spotify integration directly inside the web app, while also tracking chat analytics.
