Rate and size limits

HTTP 429 refuses admission because of request rate, concurrency or credits. Inspect the body, account balance and Retry-After when present. Back off with jitter and reduce concurrent reads. Never automatically replay payments, confirmed ask actions or webhook registration.

Process-local limits are not global throughput guarantees. Shared credit balances and watch-item entitlements can refuse work earlier. There is no single declared requests-per-second promise for all REST reads. The local stdio MCP bridge caps decoded bodies at 16 MiB and total HTTP time at 30 seconds; timeout leaves billing unknown.

Search has its own area/cursor/filter bounds. Read the operation schema rather than treating the batch limit as a search limit. The schema reference and operation availability distinguish definitions from executable runtime features. Operations marked x-runtime-supported: false remain unavailable even though their schemas exist.

After an interrupted response, retain the request id and reconcile billing before replay. The errors catalogue gives code-specific recovery actions.
