IBM/mcp-context-forge

ContextForge is IBM's open-source, Apache-2.0, 3,914-star registry and proxy that federates MCP, A2A, and REST/gRPC APIs behind one clean endpoint — ships Tools Gateway (MCP, REST, gRPC-to-MCP translation, TOON compression), Agent Gateway (A2A, OpenAI-/Anthropic-compatible routing), API Gateway (rate limiting, auth, retries, reverse proxy), 40+ plugins, and OpenTelemetry tracing.

Why it matters

Useful for platform and infra teams that need a vendor-neutral, production-grade AI gateway to federate the explosion of MCP servers, A2A agents, and REST/gRPC APIs behind one observable, governable endpoint — without standing up a custom Envoy/Istio stack or wiring their own OAuth/registry.

Who should skip it

Skip if the source link, docs, or setup requirements do not match your workflow.

Risk explanation

3,914 stars is healthy but the project is still fast-evolving — pin versions and review changelogs before production; IBM-owned but Apache-2.0 with no CLA on contributions — vendor-neutral on paper, monitor IBM's product direction in case priorities shift.
