Measured tools (11)

• list_projects read-only

  Use this when the user wants to list projects accessible to the connected CronCool account, including identifiers needed to select a project. Returns each project's id, name and creation time, 50 by default and 100 at most, with a flag when more exist. Not for listing jobs.

  Parameters:

  • limit — integer — How many projects to return, from 1 to 100; defaults to 50

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_jobs read-only

  Use this when the user wants to list scheduled jobs in CronCool to inspect schedules, enabled state and the latest execution status. Returns each job's id, name, schedule, target origin, method, enabled state and last run status and time, 20 per page by default, with a cursor for more. Not for a job's full run history.

  Parameters:

  • limit — integer — Jobs per page, from 1 to 100; defaults to 20
  • cursor — string — The nextCursor of the previous page with the same projectId; absent for the first page
  • projectId — string — Only jobs of this project

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_job read-only

  Use this when the user wants to read the scheduling configuration and latest execution metadata of one CronCool job selected by its exact identifier. Returns the job's name, cron expression, type, target origin, HTTP method, content type, enabled state and last run status and time, or not-found. Not for running the job.

  Parameters:

  • jobId (required) — string — Job id (uuid)

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• run_job destructive

  Use this when the user wants to immediately execute the configured request for one CronCool job. Returns only that Croncool invoked it, not the target's response. Each call immediately sends the job's configured request again, which can write, message or bill downstream, and a repeated call sends it once more. Not for checking a run's result.

  Parameters:

  • jobId (required) — string — Job id (uuid) of the one job to run

  Hints: read-only no · destructive yes · idempotent no · open-world yes

• get_job_runs read-only

  Use this when the user wants to read execution history for one CronCool job to inspect success, failure, HTTP status and duration. Returns recent runs newest first with success or failure, HTTP status, duration and time (no response bodies), 20 by default and 100 at most. Not for starting a run.

  Parameters:

  • jobId (required) — string — Job id (uuid)
  • limit — integer — How many runs to return, from 1 to 100; defaults to 20

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_workflows read-only

  Use this when the user wants to list durable workflow definitions and run-count summaries for one CronCool project. Returns each workflow's name, run counts by status and last run time for one project, 50 by default and 100 at most. Not for individual runs.

  Parameters:

  • projectId (required) — string — Project id
  • limit — integer — How many workflows to return, from 1 to 100; defaults to 50

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_workflow_runs read-only

  Use this when the user wants to list executions of a durable workflow in CronCool, with optional workflow-name and status filters. Returns each run's id, workflow name, status, timings and error code, newest first by default, 20 per page with a cursor, filterable by workflow and status. Not for one run's steps.

  Parameters:

  • projectId (required) — string — Project id
  • sort — string — newest (default) or oldest first
  • limit — integer — Runs per page, from 1 to 100; defaults to 20
  • cursor — string — The nextCursor of the previous page with the same project, workflow, status and sort; absent for the first page
  • status — string — Only runs in this status: pending, running, completed, failed or cancelled
  • workflowName — string — Only runs of this workflow name

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_workflow_run read-only

  Use this when the user wants to read one CronCool workflow execution and a bounded page of its step statuses for troubleshooting. Returns the run's status, timings and error code plus its steps with status, attempt, timings and error code, 50 steps by default and 200 at most. Not for listing runs.

  Parameters:

  • projectId (required) — string — Project id that owns the run
  • runId (required) — string — Workflow run id
  • stepLimit — integer — How many steps to return, from 1 to 200; defaults to 50

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_webhook_subscriptions read-only

  Use this when the user wants to read CronCool webhook subscription configuration and recorded delivery failures. Returns each subscription's endpoint origin, events, active state, consecutive failures, auto-disabled flag and last delivery time, 20 by default. Works only with a signed-in user session, not an API key. Not for changing or re-enabling a webhook.

  Parameters:

  • limit — integer — How many subscriptions to return, from 1 to 100; defaults to 20
  • projectId — string — Only subscriptions of this project

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• open_croncool read-only

  Use this when the user wants to open the CronCool project-selection sidebar when the user requests an interactive project and job browser. Returns up to 100 projects to start from (no request payloads, workflow bodies, secrets or full target URLs). Not for running jobs or changing their configuration.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• show_project_overview read-only

  Use this when the user wants to render a read-only overview of one CronCool project and a bounded preview of its scheduled jobs.
