No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

100/100 tools missing one or more hints — compras_versao (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); compras_healthcheck (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); compras_aggregate_contratacoes_por_periodo (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +97 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.
