1MCP - One MCP Server for All

A unified Model Context Protocol server implementation that aggregates multiple MCP servers into one.

Overview

1MCP (One MCP) is designed to simplify the way you work with AI assistants. Instead of configuring multiple MCP servers for different clients (Claude Desktop, Cherry Studio, Cursor, Roo Code, Claude, etc.), 1MCP provides a single, unified server.

Features

• 🔄 Unified Interface: Aggregates multiple MCP servers into one
• 🔒 OAuth 2.1 Authentication: Production-ready security with scope-based authorization
• ⚡ High Performance: Efficient request forwarding with proper error handling
• 🛡️ Security First: Stdio transport isolation, input sanitization, and comprehensive audit logging
• 🔧 Easy Configuration: Single JSON configuration file with hot-reload support
• 📈 Health Monitoring: Built-in health check endpoints for monitoring and observability

Quick Start

1. Install 1MCP

Binary (Recommended - No Node.js Required):

# Linux/macOS
curl -L https://github.com/1mcp-app/agent/releases/latest/download/1mcp-linux-x64.tar.gz | tar -xz
sudo mv 1mcp /usr/local/bin/

# Windows (PowerShell)
Invoke-WebRequest -Uri "https://github.com/1mcp-app/agent/releases/latest/download/1mcp-win32-x64.zip" -OutFile "1mcp.zip"
Expand-Archive -Path "1mcp.zip" -DestinationPath "."

NPM:

npx -y @1mcp/agent --help

2. Add MCP Servers

1mcp mcp add context7 -- npx -y @upstash/context7-mcp
1mcp mcp add filesystem -- npx -y @modelcontextprotocol/server-filesystem ~/Documents

3. Start the Server

1mcp

4. Connect Your AI Assistant

For Cursor, add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "1mcp": {
      "url": "http://127.0.0.1:3050/mcp?app=cursor"
    }
  }
}

For VSCode, add to settings.json:

{
  "servers": {
    "1mcp": {
      "url": "http://127.0.0.1:3050/mcp?app=vscode"
    }
  }
}

Install MCP Server to VSCode

For Claude Code:

claude mcp add -t http 1mcp "http://127.0.0.1:3050/mcp?app=claude-code"

That's it! All your MCP servers are now available through one unified endpoint. 🎉

Commands

Core Commands

• 1mcp [serve] - Start the 1MCP server (default command)
• 1mcp mcp add - Add a new MCP server to configuration
• 1mcp mcp list - List all configured MCP servers
• 1mcp mcp status [name] - Show server status and details

How It Works

1MCP acts as a proxy, managing and aggregating multiple MCP servers. It starts and stops these servers as subprocesses and forwards requests from AI assistants to the appropriate server. This architecture allows for a single point of entry for all MCP traffic, simplifying management and reducing overhead.
