MCP Tool Builder

An MCP server that empowers LLMs to dynamically create new tools through MCP clients such as Claude Desktop.

Features

  • Create new tools by describing them in natural language
    • Requires client restart to use new tools (Claude Desktop)
  • New tools are saved as python scriptlets in ...\mcp-tool-builder\tools
  • New tool definitions are saved in ...\mcp-tool-builder\tools\tools.json

Example tools included at installation

  • get_bitcoin_price: Fetches current Bitcoin price from CoinGecko
  • get_weather_forecast: Gets weather for US ZIP codes (uses geopy)

Creating New Tools

Use the create_tool command in Claude Desktop (or suggest strongly!!) to create new tools dynamically

  1. Clone this repository
  2. Install dependencies:
cd mcp-tool-builder uv venv .venv\Scripts\activate uv pip install -e .
