README

MCPBox is a lightweight gateway that exposes local stdio-based MCP servers via Streamable HTTP, enabling Claude and other AI agents to connect from anywhere.

  • Runs multiple servers behind a single HTTP endpoint
  • Supports Tools, Resources & Prompts
  • Namespaces with servername__ prefix to avoid collisions
  • Per-server tool filtering to limit AI access and reduce context usage
  • OAuth 2.1, API key, or no auth

{
  "mcpServers": {
    "memory": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-memory"]
    },
    "sequential-thinking": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-sequential-thinking"]
    }
  }
}

Run:

npx mcpbox
