✨ What is MCP Gateway?

MCP Gateway is a lightweight and highly available gateway service written in Go. It enables individuals and organizations to convert their existing MCP Servers and APIs into services compliant with the MCP Protocol — all through configuration, with zero code changes.

🔧 Core Design Principles

• ✅ Zero Intrusion: Platform-agnostic, supports deployment on bare metal, VMs, ECS, Kubernetes, etc., without modifying existing infrastructure
• 🔄 Configuration-Driven: Convert legacy APIs to MCP Servers using YAML configuration — no code required
• 🪶 Lightweight & Efficient: Designed for minimal resource usage without compromising on performance or availability
• 🧭 Built-in Management UI: Ready-to-use web interface to simplify setup and reduce operational overhead

🚀 Getting Started

MCP Gateway supports a ready-to-run Docker deployment. Full deployment and configuration instructions are available in the docs.

Quick Launch with Docker

Configure environment variables:

export OPENAI_API_KEY="sk-eed837fb0b4a62ee69abc29a983492b7PlsChangeMe"
export OPENAI_MODEL="gpt-4o-mini"
export APISERVER_JWT_SECRET_KEY="fec6d38f73d4211318e7c85617f0e333PlsChangeMe"
export SUPER_ADMIN_USERNAME="admin"
export SUPER_ADMIN_PASSWORD="297df52fbc321ebf7198d497fe1c9206PlsChangeMe"

Launch the container:

docker run -d \
  --name mcp-gateway \
  -p 8080:80 \
  -p 5234:5234 \
  -p 5235:5235 \
  -p 5335:5335 \
  -p 5236:5236 \
  -e ENV=production \
  -e TZ=Asia/Shanghai \
  -e OPENAI_API_KEY=${OPENAI_API_KEY} \
  -e OPENAI_MODEL=${OPENAI_MODEL} \
  -e APISERVER_JWT_SECRET_KEY=${APISERVER_JWT_SECRET_KEY} \
  -e SUPER_ADMIN_USERNAME=${SUPER_ADMIN_USERNAME} \
  -e SUPER_ADMIN_PASSWORD=${SUPER_ADMIN_PASSWORD} \
  --restart unless-stopped \
  ghcr.io/mcp-ecosystem/mcp-gateway/allinone:latest

Access and Configuration

1. Access the Web Interface:

   • Open http://localhost:8080/ in your browser
   • Login with the administrator credentials you configured

2. Add an MCP Server:

   • Copy the config from: https://github.com/mcp-ecosystem/mcp-gateway/blob/main/configs/proxy-mock-server.yaml
   • Click "Add MCP Server" in the web interface
   • Paste the configuration and save

Available Endpoints

After configuration, the service will be available at these endpoints:

• MCP SSE: http://localhost:5235/mcp/user/sse
• MCP SSE Message: http://localhost:5235/mcp/user/message
• MCP Streamable HTTP: http://localhost:5235/mcp/user/mcp

Configure your MCP Client with the /sse or /mcp suffix URLs to start using it.

Testing

You can test the service using:

1. The MCP Chat page in the web interface
2. Your own MCP Client (recommended)
