Maximum 1 request per second and 15,000 requests per month.

How do I install and prepare the server for development?

You need Node.js >= 18, pnpm >= 8.0.0, then run `pnpm install` and `pnpm run build` (or `pnpm run watch` for auto-rebuild). The MCP Inspector is available via `pnpm run inspector`.
