+description: Generates an agent-ready stack from an OpenAPI description — a runnable MCP server (stdio and Streamable HTTP), llms.txt, and an auth.md agent-signup endpoint issuing scoped, hashed, metered API keys. Also produces a curation report flagging weakly documented operations.

+Keymaker turns an OpenAPI description into everything an AI agent needs to discover, sign up for, and call an API:
+
+- **MCP server** — every operation exposed as a tool, runnable over stdio or served as hosted Streamable HTTP
+- **llms.txt** — an agent-readable API overview
+- **auth.md + agent signup** — a `/agent-auth` endpoint issuing scoped, hashed, usage-metered API keys, following the auth.md pattern, with optional Stripe usage-based billing
+- **Curation report** — flags operations and parameters with missing or weak documentation, since generated tools are only as good as the descriptions behind them

+MIT licensed, plain Node.js (18+). The generated gateway can also be mounted inside an existing `node:http` or Express app.
