mcp-toolbox

Release Build status codecov Commit activity License

A comprehensive toolkit for enhancing LLM capabilities through the Model Context Protocol (MCP). This package provides a collection of tools that allow LLMs to interact with external services and APIs, extending their functionality beyond text generation.

Features

*nix is our main target, but Windows should work too.

  • Command Line Execution: Execute any command line instruction through LLM
  • Figma Integration: Access Figma files, components, styles, and more
  • Extensible Architecture: Easily add new API integrations
  • MCP Protocol Support: Compatible with Claude Desktop and other MCP-enabled LLMs
  • Comprehensive Testing: Well-tested codebase with high test coverage

Installation

Using uv (Recommended)

We recommend using uv to manage your environment.

# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh  # For macOS/Linux
# or
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"  # For Windows

Then you can use uvx "mcp-toolbox@latest" stdio as commands for running the MCP server for latest version. Audio and memory tools are not included in the default installation., you can include them by installing the all extra:

[audio] for audio tools, [memory] for memory tools, [all] for all tools

uvx "mcp-toolbox[all]@latest" stdio

Installing via Smithery

To install Toolbox for LLM Enhancement for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @ai-zerolab/mcp-toolbox --client claude

Using pip

pip install "mcp-toolbox[all]"

And you can use mcp-toolbox stdio as commands for running the MCP server.

Configuration

Environment Variables

The following environment variables can be configured:

  • FIGMA_API_KEY: API key for Figma integration
  • TAVILY_API_KEY: API key for Tavily integration
  • DUCKDUCKGO_API_KEY: API key for DuckDuckGo integration
  • BFL_API_KEY: API key for Flux image generation API

Memory Storage

Memory tools store data in the following locations:

  • macOS: ~/Documents/zerolab/mcp-toolbox/memory (syncs across devices via iCloud)
  • Other platforms: ~/.zerolab/mcp-toolbox/memory

Full Configuration

To use mcp-toolbox with Claude Desktop/Cline/Cursor/..., add the following to your configuration file:

{
  "mcpServers": {
    "zerolab-toolbox": {
      "command": "uvx",
      "args": ["--prerelease=allow", "mcp-toolbox@latest", "stdio"],
      "env": {
        "FIGMA_API_KEY": "your-figma-api-key",
        "TAVILY_API_KEY": "your-tavily-api-key",
        "DUCKDUCKGO_API_KEY": "your-duckduckgo-api-key",
        "BFL_API_KEY": "your-bfl-api-key"
      }
    }
  }
}

For full features:

{
  "mcpServers": {
    "zerolab-toolbox": {
      "command": "uvx",
      "args": [
        "--prerelease=allow",
        "--python=3.12",
        "mcp-toolbox[all]@latest",
        "stdio"
      ],
      "env": {
