Model Context Protocol
Build your
own MCP.
Describe the tools you want and Brevosi builds, deploys and hosts a real MCP server for you, from your phone. Or hand the job to Claude or ChatGPT through your personal builder endpoint and watch it appear live.

What it does
From idea to a live MCP server, three ways.
Describe it, an agent builds it
Say what tools you want. A cloud agent writes the backend, deploys it and hands back a live MCP URL, verified before you ever see it.
Or bring your own agent
Connect Claude or ChatGPT to your personal builder endpoint and ask it to do the building. Tools go live the moment it calls publish.
Hosted the second it exists
Every server gets a public Streamable HTTP endpoint with persistent state. Templates go live in about two seconds.

The protocol
Agents are first-class users.
Brevosi itself speaks MCP. Your personal builder endpoint gives any agent typed tools to create, test and publish servers, with the full playbook delivered in band through the initialize instructions.
The docs are written for models first: llms.txt on every endpoint, and every error names the exact next call to make.
