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.
Dispatch
Route $ARGUMENTS to the appropriate mode:
| $ARGUMENTS pattern | Mode | Start at |
|---|---|---|
| Service/API name (e.g., "GitHub", "Stripe") | New server | Phase 1 |
Path to existing first-party server (e.g., mcp/myserver/) |
Extend | Phase 3 |
| OpenAPI spec URL or file path | Convert OpenAPI | Phase 2 (scaffold) then load references/server-composition.md §6 |
