- Support for more MCP server types and sources (e.g., Node.js, Java, etc.)
- Support recovery mechanism for failed installations
- ...
- 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
- Python 3.10 or higher
- pip (for Python packages)
- Node.js and npm (optional, for JavaScript packages)
git clone https://github.com/xd3an/mcp-builder.git cd mcp-builder pip install -e .
After installation, you can run the MCP Builder directly:
# Using the entry point mcpbuilder # Or as a module python -m mcp_builder.server
For development and testing, you can use the MCP CLI tools:
# 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
To use MCP Builder with Claude Desktop, add it to yourclaude_desktop_config.jsonfile:
{ "mcpServers": { "mcp-builder": { "command": "python", "args": [ "-m", "mcp_builder.server" ] } } }
- Windows:%APPDATA%\Claude\claude_desktop_config.json
- macOS:~/Library/Application Support/Claude/claude_desktop_config.json
- Linux:~/.config/Claude/claude_desktop_config.json
Once integrated with Claude Desktop, you can ask Claude to:

MCP Builder modifies the Claude Desktop configuration file to register MCP servers. It supports:
- Node.js Packages: Installs usingnpxand configures Claude to use them
- Python Packages: Configures Claude to use Python modules
- Local Repositories: Installs dependencies and configures Claude to use local code
