All four hints declared on every tool

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

10 critical, 44 high severity in production deps — form-data@4.0.0 (critical), n8n@2.8.3 (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.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 3 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
