MCP Server Development Guide

Overview

Create MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools.

Process

1. Research & Planning: Understand MCP design, study specification, and framework documentation.
2. Implementation: Set up project structure, implement core infrastructure (auth, error handling), and develop tools with clear schemas and descriptions.
3. Review & Test: Verify code quality, run builds, and test with MCP Inspector.
4. Evaluations: Create realistic evaluation questions to test the server's effectiveness.
