MCP.Pizza Chef: braincrew-lab

Rather than using someone else's chat app, you run this one on your own machine: a simple web page where you paste in the tools you want, apply them, and start asking questions. Every tool call shows up as it happens, and the conversation history is kept. It starts through Docker or Python, needs a key from OpenAI or Anthropic to power the replies, and can sit behind a simple login. The project has not been updated since April 2025.

langgraph-mcp-agents FAQ

Is this something I add to Claude?

No, it is the other side of the arrangement — a chat app of your own that other tools plug into.

Do I need a paid key?

Yes. Replies come from OpenAI or Anthropic models, so you supply your own key for whichever you choose.

How hard is setup?

Developer level. You install Docker or Python, copy an example settings file and start the app yourself.

Can I use this to test a tool I found on Smithery?

Yes — copy the settings shown on Smithery, paste them into the sidebar and hit apply.

Is it still maintained?

The repository has had no updates since April 2025, so treat it as a working demo rather than a supported product.

Where does it run?

In your browser at a local address after you start it, not on anybody else's servers.
