What Are MCP Apps?
MCP started as tool calls and grew a real UI layer that is now an official part of the protocol. What an MCP app is, how returning UI works, when you need it, and how to build one with mcp-use.
Manufact is live in the ChatGPT App Store
Deploy, debug, and monitor your MCP servers from a ChatGPT conversation. The Manufact app is now available in the ChatGPT App Store.
Manufact is now a Claude connector
Manufact is available as a connector on Claude. Published connectors are discoverable to every Claude user, and our signups jumped more than 10x after publication.
The road to 10,000 stars
The history of mcp-use, told as a pull request, from the first commit to 10,000 GitHub stars. Commits are what we shipped; comments are what happened.
How iAhorro shipped a mortgage simulation app on ChatGPT in 4 days
iAhorro went from an early prototype to a production-ready MCP App on ChatGPT in days, using mcp-use and Manufact Cloud.
How Meilleurtaux became the first French broker to launch a mortgage app on ChatGPT
Meilleurtaux is the first credit and mortgage broker in France to launch a dedicated app on ChatGPT. They built a borrowing-capacity simulator on top of their real-time data with mcp-use and Manufact Cloud, in under two months.
How item exposed its product agent to ChatGPT and Claude with mcp-use
item already had a great internal agent inside their Next.js app. Their customers wanted to use it from their own agents. Here is how item shipped a production MCP server from the same repo, reusing the tools they already had and exposing the agent itself as a tool.
How Simera turned its global talent database into an agent
Simera spent years building more than a resume database: structured professional data with pre-screened skills, communication scores, and verified hiring alignment. That proprietary intelligence was the moat, but every match still ran through a person. Here is how they turned it into Agent David, one MCP app that serves their customers, their website, and their own operations team.
Migrating from Stainless: OpenAPI to MCP with mcp-use and Manufact
Stainless is shutting down its MCP product. Here's how to port your OpenAPI-to-MCP pipeline to mcp-use and Manufact Cloud — including when to ship a 1:1 server vs. a curated MCP App.

How we built the mcp-use screenshot CLI to close your agent's automatic feedback loop when developing MCP Apps
We Made MCP Testing Less Painful
Testing MCP servers is painful: slow install loops, behavior that differs across clients, and no good way to know if your agents are calling tools correctly. Here's how we fixed it.
Deploying Seven MCP Frameworks: A Field Report
Same echo + greet_widget example, seven MCP frameworks, one Manufact Cloud deploy pipeline. What broke, what surprised us, and per-framework deploy notes.
How to Deploy FastMCP to Production
How we deployed a FastMCP echo + Prefab greet_widget example to Manufact Cloud: GitHub connect, port 8000, and what breaks when the starter lockfile drifts.
How to Deploy an MCP Python Server to Production
Deploy steps for a FastMCP-based Python MCP app on Manufact Cloud, plus the reference server (echo + greet_widget) and DNS-rebinding gotchas behind the proxy.
