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
