MCP Gateway Registry

Canonical version: MCP Gateway Registry.

The MCP Gateway Registry is an open-source (Apache 2.0 License) project from the Agentic Community that provides a single, governed control plane for every AI asset in an organization: MCP servers, AI agents, skills, and custom assets. It is both a gateway (one entry point that routes client requests to many registered MCP servers) and a registry (discovery plus access governance). The goal: turn scattered MCP-server sprawl into auditable, controlled tool access.

What it does

• MCP server gateway: routes requests from clients to registered MCP servers through one endpoint
• MCP server registry: registration, discovery, and access governance for servers
• Agent registry: register and discover agents over the A2A (Agent-to-Agent) protocol
• Skills registry: manage reusable instruction sets (SKILL.md) with security scanning
• Custom entity registry: admins define their own entity types with custom schemas

Governance and security

This is the point of the project, not just discovery:

• OAuth 2.0/3.0 with enterprise identity providers (Keycloak, Microsoft Entra ID, Okta, Auth0, Cognito, PingFederate)
• Fine-grained access control down to tool and method level; full audit logging
• Dual auth for both humans (devs using AI assistants) and machines (autonomous agents)
• Integrated vulnerability scanning (Cisco AI Defense) for MCP servers and A2A agents
• Unified semantic search (vector + keyword) and dynamic tool discovery so agents find capabilities at runtime

Compatibility and stack

Compatible with Anthropic's MCP Registry REST API specification (see Model Context Protocol Registry). Built with Python/FastAPI behind an Nginx reverse proxy, MongoDB/DocumentDB storage, deployable via Docker, Podman, Kubernetes (Helm), or AWS ECS (Terraform).
