These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

schedule_job

Create a scheduled prompt. When the cron expression matches, cron-mcp POSTs { jobId, name, prompt, metadata, firedAt } to your callback URL (signed with X-Cron-Signature). Use for daily briefings, hourly polls, weekly digests — anything that repeats on a fixed schedule. For one-shot 'in 3 minutes' n…

list_jobs

Return all cron jobs owned by the calling API key, active and paused.

get_job

Return one job by id, plus its most recent 20 fire attempts (audit log).

update_job

Modify an existing job. Pass only the fields you want to change; unspecified fields are preserved. Set `isActive: false` to pause without deleting.

delete_job

Permanently delete a job and all its run history. Prefer pausing (update_job.isActive=false) if you might revive it.

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

5/5 tools missing one or more hints — schedule_job (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_jobs (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_job (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +2 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.

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

4 critical, 13 high severity in production deps — next@16.1.6 (critical), next@16.1.6 (critical)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// 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 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
