17/20 tools missing one or more hints — n8n_create_workflow (missing: idempotentHint); n8n_get_workflow (missing: destructiveHint); n8n_delete_workflow (missing: idempotentHint), +14 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
16 critical, 49 high severity in production deps — form-data@4.0.0 (critical), n8n@2.3.3 (critical)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
13 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
