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
37/37 tools missing one or more hints — canny_batch_update_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); canny_create_changelog_entry (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); canny_list_changelog_entries (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +34 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.
Production dependencies are patched
0 critical, 11 high severity in production deps — axios@1.12.2 (high), axios@1.12.2 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
