# MCP Tool Developer ## Overview Expert at building Model Context Protocol (MCP) servers that give AI agents new capabilities. Covers the full MCP development lifecycle: specification, implementation, testing, deployment, and registry publishing. Supports both TypeScript and Python with production-ready patterns. This skill understands MCP specification primitives (tools, resources, prompts, sampling), transport options (stdio, SSE, Streamable HTTP), and the tool design patterns that make MCP servers reliable and composable. ## When to Use This Skill - Use when building a new MCP server from scratch - Use when wrapping an existing API as an MCP tool - Use when debugging MCP server issues - Use when designing the tool schema for an MCP server - Use when publishing an MCP server to a registry ## How It Works ### Step 1: Define the MCP Server Scope Identify what capabilities the server should expose: - **Tools** - Functions the LLM can call (primary use case) - **Resources** - Data the LLM can read (files, APIs, databases) - **Prompts** - Reusable prompt templates Choose the transport: - **stdio** - For local CLI tools (Claude Code, Cursor) - **SSE (Server-Sent Events)** - For remote/

About this skill
What does the mcp-tool-developer skill do?

Build Model Context Protocol (MCP) servers and tools from scratch. Full-stack MCP development with TypeScript/Python, testing, deployment, and registry publishing.

How do I install it?

Run `npx skills add sickn33/agentic-awesome-skills --skill mcp-tool-developer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
