MCP Builder is a Python-based server that installs and configures other MCP servers for integration with MCP clients like Claude Desktop.
Install MCP servers from package repositories (PyPI or npm packages) using
install_repo_mcp_server
Install MCP servers from local directories using
install_local_mcp_server
for locally cloned codeConfigure installed servers with custom environment variables and command-line arguments
Automatically detect server type (Python or Node.js) during installation
Cross-platform compatibility supporting Windows, macOS, and Linux
Client integration by automatically modifying Claude Desktop's configuration file to register installed servers
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
Enables installation of MCP servers from PyPI packages
Installs and configures Python-based MCP servers, supporting PyPI packages as MCP server sources
mcp-builder

MCP Client Integration
Claude Desktop Integration
To use MCP Builder with Claude Desktop, add it to your claude_desktop_config.json
file:
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:

How It Works
MCP Builder modifies the Claude Desktop configuration file to register MCP servers. It supports:
Node.js Packages: Installs using
npx
and configures Claude to use themPython Packages: Configures Claude to use Python modules
Local Repositories: Installs dependencies and configures Claude to use local code
