ContextForge
An open-source registry and proxy that federates MCP, A2A and REST or gRPC APIs behind one endpoint, adding centralized governance, discovery, observability and plugin extensibility for AI infrastructure.
ContextForge is an open-source registry and proxy that federates tools, agents and APIs from multiple MCP, A2A and REST/gRPC services into one clean endpoint for AI clients, with centralized governance, discovery and observability. Its Tools Gateway handles MCP, REST and gRPC-to-MCP translation with TOON compression; its Agent Gateway routes A2A protocol and OpenAI- or Anthropic-compatible agent traffic; and its API Gateway adds rate limiting, authentication, retries and a reverse proxy for REST services.
More than 40 plugins extend it with additional transports, protocols and integrations, and it exports OpenTelemetry traces to backends such as Phoenix, Jaeger and Zipkin. It runs as a fully compliant MCP server, deployable through PyPI or Docker, and scales to multi-cluster Kubernetes environments with Redis-backed federation and caching.
