What is MCP Gateway & Registry?

MCP Gateway & Registry is a unified platform that combines centralized access control with intelligent tool discovery for Model Context Protocol (MCP) servers. It consists of a Registry providing visual and programmatic interfaces for exploring available MCP servers and tools, and a Gateway (NGINX reverse proxy) ensuring secure, governed access to all services. It is designed for enterprises and developers building AI agents that need to discover, access, and manage multiple MCP servers through a single endpoint.

How to use MCP Gateway & Registry?

Deploy the Gateway and Registry on Amazon EC2 or Amazon EKS. For EC2, clone the repository, build the Docker container, and run it with environment variables for admin credentials and API keys. Access the Registry web UI at http://localhost:7860. AI agents connect to MCP servers via the Gateway's single endpoint by appending the server-specific path (e.g., https://my-mcp-gateway.enterprise.net/weather/). The Gateway supports both SSE and Streamable HTTP transports.

Key features of MCP Gateway & Registry

• MCP tool discovery via natural language queries

• Service registration via JSON files, web UI, or API
• Web UI for managing services, status, and health
• Secure login for web UI and API access
• Periodic health checks with real-time WebSocket updates
• Dynamic NGINX reverse proxy configuration generation

Use cases of MCP Gateway & Registry

• Centralize enterprise MCP server access behind a single secure gateway
• Enable AI agents to dynamically discover and invoke new tools
• Govern which MCP servers are available to developers and agents
• Simplify multi-server MCP client configuration for agent frameworks

FAQ from MCP Gateway & Registry

What runtime dependencies are required?

An Amazon EC2 instance (recommended ml.t3.2xlarge) with Ubuntu, Docker, and an SSL certificate (self-signed or real). Example MCP servers may require third-party API keys (e.g., Polygon.io).

Which MCP transports are supported?

The Gateway supports both SSE (Server‑Sent Events) and Streamable HTTP transports.

Can I deploy on Kubernetes?

Yes, the repository provides installation instructions for Amazon EKS (Elastic Kubernetes Service) for production environments.

Is authentication supported?

Yes, the Registry includes a secure login system for both the web UI and API access.

What is the current stability of the project?

The repository is under active development with frequent updates and breaking changes. The API is considered experimental. Pin to specific versions for production use.
