ContextForge
agentgatewayContextForge and agentgateway both target MCP traffic but differ in scope. ContextForge is IBM's Python-based AI gateway with an admin UI, Cedar ABAC, plugin ecosystem, and federation across MCP, A2A, REST, and gRPC. agentgateway is a Rust-based Linux Foundation project focused on high-throughput policy enforcement via Envoy-style filters, configured declaratively through the Kubernetes Gateway API.
ContextForgeContextForge and MetaMCP are both MCP federation gateways. ContextForge is IBM's Apache 2.0 platform with Cedar-based RBAC, 40+ plugins, and a heavier operational footprint; MetaMCP is MIT with a simpler Servers-Namespaces-Endpoints model and lighter deployment.
Docker MCP Gateway
ContextForgeBoth tools centralize MCP server access behind a gateway layer, but ContextForge extends beyond containerized MCP routing into registry, A2A, REST/gRPC translation, and built-in observability. Docker MCP Gateway is the lighter-weight option for Docker-centric MCP aggregation, while ContextForge targets broader agent platform control planes.
