Expose an HTTP server

Use "kind": "http" when you already have a Streamable HTTP MCP server running locally and just want mcpwarp to proxy it.

Add the server to your config

~/.mcpwarp/config.json

{
  "servers": [
    { "name": "notes", "kind": "http", "url": "http://127.0.0.1:8765/mcp" }
  ]
}

• url — the local Streamable HTTP endpoint mcpwarp should proxy to.
• name — must match ^[a-z0-9]([a-z0-9-]*[a-z0-9])?$, 1–30 characters, and be unique in your config. It’s also the public URL slug. Renaming a server mints a brand-new URL; the old one lingers offline in the dashboard until you delete it.

The legacy 2024-11-05 HTTP+SSE transport (a GET /sse endpoint plus POST /messages) is not supported. Your server needs to speak Streamable HTTP.

Start it

mcpwarp status   # validate the config first
mcpwarp up

NAME   KIND   URL
notes  http   https://notes-anatoly.tunnel.mcpwarp.io/mcp

mcpwarp proxies requests to your local server and streams the response back end to end, with backpressure.
