HOSTUSPTO_API_KEY[data.uspto.gov](https://data.uspto.gov/) → MyODPUSPTO_BASE_URLUSPTO_TIMEOUTAll four hints declared on every tool
12/45 tools missing one or more hints — bigquery-patent-search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); bigquery-patent-family (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); bigquery-citation-network (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +9 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
