About

Tool Builder is an MCP server that allows Large Language Models (LLMs) to create new tools on-the-fly through MCP clients like Claude Desktop. Users can define tools using natural language, which are then saved as Python scriptlets. The server includes example tools like fetching Bitcoin prices and weather forecasts to get started. This enables a flexible and adaptable toolset that can evolve based on the user's needs.
