# Create MCP Server

Put an outside service in reach of the model as real tools

## What this does

There is a service you use that the model cannot reach, and you want it to. This walks through building the bridge that exposes it as tools, from working out what the tools should be through to testing it. Reach for it when you want a model to actually do something in a system rather than just talk about it.

### Top 3 things it does for you

- Build an MCP server for a service
- Wrap an existing API as tools
- Test a server and prove it works

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Create MCP Server

This is for building, iterating on and evaluating Model Context Protocol servers that expose external services as tools an LLM can call.

Use it when you want to build an MCP server, create an MCP tool, wrap an API as MCP, expose something to Claude, or extend GSD with custom tool integrations.

It covers research, schema and tool design, error handling, pagination, testing via MCP Inspector, and producing an eval set that proves the server actually enables real work.

## Questions

### Is Create MCP Server safe to install?

AIR scanned this exact version of Create MCP Server and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 4ea7d80e76af, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/create-mcp-server.

### How do I install Create MCP Server?

Open https://airmarket.ai/app/create-mcp-server on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/gsd-build/gsd-2/tree/4ea7d80e76af01a6c566a44989b451bae51ec6f3/src/resources/skills/create-mcp-server. Install from that link, not the branch.
