Python MCP Server

Example Use Cases

• 1

  Run simple arithmetic tools or other custom utility functions exposed via MCP.

• 2

  Access environment-based secrets (like API keys) in a controlled, local development environment.

• 3

  A reference/example MCP server to integrate with Cursor AI or to learn how to expose tools over stdio and via mcp.json configuration.

Description

This repository demonstrates a simple Model Context Protocol (MCP) server implemented in Python that provides two example tools: an add tool that sums two numbers and a getApiKey tool that returns an API key from the environment. It includes CLI support, standard I/O transport for IDE integration, and an example mcp.json to help Cursor AI discover and launch the server. The project is intended as a lightweight starter template for building and testing MCP tools locally and integrating them into agent workflows.
