MCP-S Gateway

mcp-gateway is a secure gateway and integration layer for the Model Context Protocol (MCP). It provides a unified, enterprise-ready interface for connecting, managing, and extending MCP modules and services, with a focus on security and seamless integration.

Quick Start

1. Configure your MCP servers - Create mcp.json file in your project:

{
  "mcpServers": {
    "your-server": {
      "command": "npx",
      "args": ["-y", "@your-mcp-server"],
      "env": {
        "API_KEY": "your-api-key"
      }
    },
    "octocode": {
      "command": "npx",
      "args": ["octocode-mcp"]
    }
  }
}

2. Use the .env.example file as a base, and override as needed:

3. Start with npx (Recommended):

# Default (uses ./mcp.json and ./.env)
npx @mcp-s/secure-mcp-gateway

# Custom configuration paths
npx @mcp-s/secure-mcp-gateway --mcp-config ./custom/mcp.json --envfile ./custom/.env

Or clone:

git clone https://github.com/mcp-s-ai/secure-mcp-gateway.git && cd secure-mcp-gateway
npm install && npm run start

4. Add to your MCP configuration:

stdio:

{
  "mcpServers": {
    "mcp-gateway": {
      "command": "npx",
      "args": ["-y", "@mcp-s/mcp"],
      "env": {
        "BASE_URL": "http://localhost:3000"
      }
    }
  }
}

Streamable HTTP Configuration:

{
  "mcpServers": {
    "mcp-gateway": {
      "url": "http://localhost:3000/mcp"
    }
  }
}
