MCP Server Development Guide

Overview

Create MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. The quality of an MCP server is measured by how well it enables LLMs to accomplish real-world tasks.

When to Use

• You need to design or build an MCP server that wraps APIs or services for LLM consumption.
• You want to define tooling, error handling, schema validation, and evaluation questions before deployment.
• You are choosing between frameworks (TypeScript vs Python) and need workflow guidance.

When NOT to Use

• You are building a standard API or microservice without LLM control-plane tooling.
• The work is purely research or architecture discussion with no MCP implementation yet.
• The project uses non-MCP protocols or frameworks unrelated to Model Context Protocol.
