Integrations

  • Supports installing MCP servers directly from GitHub repositories like playwright-mcp

  • Installs and configures Node.js-based MCP servers, supporting npm packages as MCP server sources

  • Enables installation of MCP servers from npm packages

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.

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

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:

# 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:

# 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:

{ "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
