mcp-use: Build MCP Apps Fast

The story

What the video said

mcp use is an open source project that turns a plain chat prompt into a working app. It helps you build tools that AI assistants like ChatGPT and Claude can call.

You want to see your AI tool answer a real question with a chart, but you don’t want to write lots of setup code just to test one simple idea.

mcp use is an open source library for building MCP servers, clients, and apps. It gives you a ready made Inspector so you can run and check your tools in the browser.

You type a request into the Inspector chat, and it sends that request to your tool. The tool returns structured data, and the Inspector shows the result right there on the screen.

In the demo, you ask for a quarterly revenue bar chart. The Inspector shows a loading spinner, then a rendered blue bar chart with a bulleted summary of the values.
