The Brevosi My MCPs screen, listing servers you have built

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 a real Convex backend, deploys it, and hands back a live MCP URL, verified before you see it.

Or bring your own agent

Connect Claude or ChatGPT to your personal builder MCP and ask it to do the building. Tools go live the moment it calls publish. No VM, no wait.

Hosted the second it exists

Every MCP gets a public Streamable-HTTP endpoint any client can use, with persistent state per server. Templates go live in about two seconds.

Every screen

From plain English to a live endpoint, on a phone.

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 via initialize instructions.

Docs are written for LLMs first: llms.txt on every endpoint, and every error tells the agent the exact next call to make.

→ tools/call create_mcp
    {"name":"Dice Roller"}
← {"slug":"dice-roller-x7k2m9"}
→ tools/call define_tool
    {"name":"roll_dice","code":"..."}
→ tools/call publish
← {"url":"https://.../m/dice-roller-x7k2m9/mcp",
   "next":"Tell the user their MCP is live."}
