Rate Limits

Limits are per key, and per client address for the shared demo key — so one noisy demo user cannot exhaust it for everyone.

Exceeding the limit returns 429 with a Retry-After header in seconds:

{
  "error": {
    "code": "rate_limited",
    "message": "Too many requests. Slow down and retry.",
    "retry_after_ms": 4200
  }
}

Back off for Retry-After rather than retrying immediately. The MCP endpoint shares these buckets, so switching transport does not double your budget.
