Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
cron_presets ~73
Return a library of common cron expression presets (every 5 min, hourly, daily at midnight, weekdays 9am, monthly, quarterly, yearly, etc.) with their plain-English labels. Use this when a user asks for a "common" or "standard" schedule and you want to offer proven starting points.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
next_runs ~103
Compute the next N scheduled run times for a cron expression. Returns ISO-8601 timestamps with relative offsets (+5m, +1h, +2d). Use this to preview when a job will actually fire before committing it.
| Name | Type | Req | Description |
|---|---|---|---|
| count | number | – | How many future runs to compute (default 5, max 50). |
| expression | string | yes | The cron expression. |
| from | string | – | ISO-8601 start time (defaults to now). |
No output schema declared.
No examples provided.
parse_cron ~117
Parse a cron expression and return a human-readable description of when it fires. Supports 5-field standard cron (min hour dom month dow) plus extensions: L (last day/weekday), W (nearest weekday), # (nth weekday), and named months/days (JAN..DEC, SUN..SAT). Use this to explain any cron schedule in plain English.
| Name | Type | Req | Description |
|---|---|---|---|
| expression | string | yes | The cron expression to parse, e.g. "*/5 * * * *" or "0 9 * * 1-5". |
No output schema declared.
No examples provided.
validate_cron ~117
Deeply validate a cron expression for correctness and common mistakes. Catches: impossible schedules (e.g. day 31 in Feb), OR-semantics gotchas (dom AND dow both restricted = either matches, not both), midnight scheduling spikes, uneven step values (*/7), leap-year edge cases, weekday-only warnings, and more. Returns warnings, observations, optimization suggestions, and an estimated yearly run count. Use this BEFORE deploying a cron job to catch silent failures.
| Name | Type | Req | Description |
|---|---|---|---|
| expression | string | yes | The cron expression to validate. |
No output schema declared.
No examples provided.
