MCP Proxy

info

This feature is under development.

We are building Model Context Protocol (MCP) support into the Radicalbit AI Gateway, so that the Gateway can act as an MCP server for your agents and proxy the MCP servers you approve.

Capability	Description
MCP proxy	Expose upstream MCP servers on a route behind a single gateway endpoint
Transports	Streamable HTTP and stdio upstreams, mixed on the same route
Tool namespacing	Tools, prompts, and resources merged across servers and prefixed with `{alias}__`
Credential isolation	Static upstream headers from `!secret`, plus a per-server allowlist for client-supplied headers
Rate limiting	The route's `rate_limiting` applies to MCP calls: one JSON-RPC POST counts as one request

Configuration

Declare the upstream servers once, then reference them from the routes that may use them.

mcp_servers:
  - alias: github
    transport: streamable_http
    url: https://api.githubcopilot.com/mcp/
    timeout: 30
    headers:
      Authorization: !secret GITHUB_MCP_TOKEN

The route then speaks MCP at POST /{project}/{route}/mcp, with the same API key as the chat endpoints:

curl http://localhost:9000/project-name/route-name/mcp \
  -H "Authorization: Bearer key" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc": "2.0", "id": 1, "method": "tools/list"}'
