About Calculator
The Calculator MCP Server is a Model Context Protocol server that enables LLMs to use a calculator for precise numerical calculations. It provides a single tool called 'calculate' that evaluates mathematical expressions. Installation is straightforward via uvx (using uv) or pip, and configuration with MCP clients is simple. The server is licensed under MIT and is available as an open-source project on GitHub.
