mcp-builder

# mcp-builder A Python-based MCP server to install other MCP servers. The purpose of this server is to provide a complete, user-friendly, and cross-platform way to install and configure MCP servers. <a href="https://glama.ai/mcp/servers/@XD3an/mcp-builder"> <img width="380" height="200" src="https://glama.ai/mcp/servers/@XD3an/mcp-builder/badge" alt="Builder MCP server" /> </a> #### TODO - [ ] Support for more MCP Clients (e.g. Cursor, Windsurf, ...) - [ ] Support for more MCP server types and sources (e.g., Node.js, Java, etc.) - [ ] Support recovery mechanism for failed installations - ... ## Features - **Package Repository Installation**: Install MCP servers from PyPI or npm packages - **Local Installation**: Install MCP servers from local directories - **Configuration Management**: Configure environment variables and arguments for installed servers - **Automatic Detection**: Automatically detect the type of MCP server (Node.js or Python) - **Cross-Platform Support**: Works on Windows, macOS, and Linux ## Requirements - Python 3.10 or higher - pip (for Python packages) - Node.js and npm (optional, for JavaScript packages) ## Installation ### Install from Source ```bash git clone https://github.com/xd3an/mcp-builder.git cd mcp-builder pip install -e . ``` ## Usage ### Running Directly After installation, you can run the MCP Builder directly: ```bash # Using the entry point mcpbuilder # Or as a module python -m mcp_builder.server ``` ### Development Mode For development and testing, you can use the MCP CLI tools: ```bash # Install MCP CLI tools pip install "mcp[cli]" # Run in development mode mcp dev path/to/mcp_builder/server.py # npx @modelcontextprotocol/inspector npx @modelcontextprotocol/inspector python -m mcp_builder.server ``` ### MCP Client Integration #### Claude Desktop Integration To use MCP Builder with Claude Desktop, add it to your `claude_desktop_config.json` file: ```json { "mcpServers": { "mcp-builder": { "command": "python", "args": [ "-m", "mcp_builder.server" ] } } } ``` The configuration file is located at: - Windows: `%APPDATA%\Claude\claude_desktop_config.json` - macOS: `~/Library/Application Support/Claude/claude_desktop_config.json` - Linux: `~/.config/Claude/claude_desktop_config.json` #### Example Commands Once integrated with Claude Desktop, you can ask Claude to: > read https://github.com/microsoft/playwright-mcp help me install playwright-mcp in my claude config  ## How It Works MCP Builder modifies the Claude Desktop configuration file to register MCP servers. It supports: 1. **Node.js Packages**: Installs using `npx` and configures Claude to use them 2. **Python Packages**: Configures Claude to use Python modules 3. **Local Repositories**: Installs dependencies and configures Claude to use local code
