MCP Proxy

mcp-proxy is the stdio-to-HTTP bridge used when a runtime does not natively expose MCP over HTTP.

Transport Role

Where It Is Used

  • wrapped stdio shared tools
  • infAct Browser (browser-use)
  • legacy stdio runtime patterns

Important Boundary

mcp-proxy is a transport helper.

It is not the security boundary.

Security still comes from:

  • API key tiering
  • integration filtering
  • ownership and runtime scope
