What ContextForge does
An open-source registry and proxy that federates MCP, A2A, and REST or gRPC APIs with centralized governance, discovery, and observability.
Why teams reach for it: Presents a mixed estate of MCP servers and existing APIs to clients as one catalogue with shared governance.
Worth knowing
It speaks stdio, SSE, Streamable HTTP to clients, aggregates multiple MCP servers behind one endpoint, terminates authentication, can host stdio servers remotely.

How will you route, mediate, and control traffic?
A gateway or proxy sits between clients and MCP servers to route traffic or add a control layer, without changing the servers themselves.
