Rate limits
Per-key request limits for REST and MCP.
| Bucket | Limit |
|---|---|
| Reads (GET) | 120 per minute per key |
| Writes (POST, PATCH, DELETE) | 30 per minute per key |
MCP tool calls count against the same buckets. Over the limit returns 429 rate_limited with Retry-After in seconds; every response carries X-RateLimit-* headers.
