MCP Creator — FastMCP v3

Build production-ready MCP servers with FastMCP v3 (3.0.0rc2). This skill guides through research, scaffolding, implementation, testing, and deployment. All first-party output follows this repo's conventions: mcp/<name>/ directory, fastmcp.json config, exact uv workspace member, imperative voice, kebab-case naming. Reserve mcp/servers/ for machine-local third-party MCP installs; it is gitignored.

Target: FastMCP v3 rc2 — Provider/Transform architecture, 14 built-in middleware, OAuth 2.1, server composition, component versioning, structured output, background tasks, elicitation, sampling.

Input: $ARGUMENTS — the service, API, or capability to wrap as an MCP server.
