MCP Context Forge

MCP Context Forge is an open source registry and proxy that federates MCP, A2A, and REST or gRPC APIs with governance and discovery.

ContextForge is an open source registry and proxy that federates tools, agents, and APIs into one clean endpoint for AI clients. It provides centralized governance, discovery, and observability across your AI infrastructure. The platform includes a tools gateway for MCP, REST, gRPC-to-MCP translation, and TOON compression, alongside an agent gateway for A2A protocol and agent routing. It supports virtualizing legacy APIs as MCP-compliant tools and servers, and includes plugin extensibility with over forty plugins. For observability, it offers OpenTelemetry tracing with backends like Phoenix, Jaeger, and Zipkin.
