    "description": "Tidemill has no accounts and no API keys by design: every tool runs free in the browser, so there is no per-customer state for an endpoint to gate. Every endpoint below is public and unauthenticated. GET /api/v1/tools and /api/v1/tools/{slug} read the same catalogue the website's /apps and /tools pages render from. POST /api/v1/license/verify checks whether a pasted Tidemill Pro license key is valid; it never issues or revokes a key, and never returns the key's contents. Lightly rate-limited per IP (see https://tidemill.io/docs/agents). The same jobs are available as MCP tools at https://tidemill.io/mcp and from the `tidemill` CLI (`npx tidemill --help`). Setup guide: https://tidemill.io/docs/agents.",
