Description, as the server wrote it: ```untrusted-server-text CREATES a new check — this MODIFIES live monitoring config. Provide a `timeout` (simple period-based check) OR a `schedule` + `tz` (cron-based check); the two are mutually exclusive. Use `unique` to avoid creating duplicates. Assign notifications via `channels`. Healthchecks: POST /checks/. Returns the created check (201) or the existing match (200). ``` ### `healthchecksio_delete_check` - The name "healthchecksio_delete_check" says "delete": a word for removing or ending something. - The description says "PERMANENTLY DELETES". - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text PERMANENTLY DELETES a check by UUID — this MODIFIES live monitoring config and cannot be undone. Healthchecks: DELETE /checks/{uuid}. Returns the deleted check's last known state. ``` ### `healthchecksio_pause_check` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text PAUSES a check — disables monitoring without deleting it (it stops going down for missed pings until it next receives a ping or is resumed). This MODIFIES live monitoring config. Healthchecks: POST /checks/{uuid}/pause (empty body). ``` ### `healthchecksio_resume_check` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text RESUMES a paused check — re-enables monitoring. This MODIFIES live monitoring config. Returns HTTP 409 (surfaced cleanly) if the check is not currently paused. Healthchecks: POST /checks/{uuid}/resume (empty body). ``` ### `healthchecksio_update_check` - The name "healthchecksio_update_check" says "update": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text UPDATES an existing check by UUID — this MODIFIES live monitoring config. Send only the fields you want to change (timeout and schedule remain mutually exclusive). Healthchecks: POST /checks/{uuid}. Returns the updated check. ``` ## Only reads (7) Looks things up and changes nothing. Claude Code: allow. ### `healthchecksio_get_check` - The name "healthchecksio_get_check" says "get": a word for reading.

Healthchecks: GET /checks/{uuid}. ``` ### `healthchecksio_get_ping_body` - The name "healthchecksio_get_ping_body" says "get": a word for reading.

Description, as the server wrote it: ```untrusted-server-text List all checks in the project, optionally filtered by slug and/or tags.
