HookPulse MCP server

• Registry namenet.hookpulse/hookpulseverified in the MCP registry

The registry name sits under hookpulse.net. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-26 the server answered initialize and tools/list without a sign-in. First answer in 206 ms.

• Whether its tools do the product's job has not been judged yet.
• Checked on 1 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• api_index

  Full index of the HookPulse API.

• health

  Liveness.

• create_guest

  Creates a guest token hp_… Keep the token: without it there is no way back to the monitors, unless you have already tied them to an e-mail.

• list_endpoints

  Lists the guest's/session's endpoints.

• create_endpoint

  Create a monitor for a routine. Use cron, tz and grace_sec for a schedule, or interval_sec for a fixed check-in interval. Set max_duration_sec to detect an open run that exceeds its time limit. With `check` the monitor is a site…

• create_site

  Monitor a website: HookPulse calls check.url every interval_sec (default 300) and alerts when it goes down and when it is back. With `check` the monitor is a site: HookPulse calls `check.url` every `interval_sec` (default 300) and alerts…

• check_site

  Check a site monitor now. One call every 10 seconds per destination host. One call every 10 seconds per destination host, for everyone: the button cannot hammer a site. The first state of a new site comes from here, without an alert — you…

• list_sites

  The state of every site you monitor (up, down, waiting, paused), with the last check.

• import_crontab

  Reads a crontab and proposes one monitor per scheduled line. Without apply=1 nothing is written; the proposal says what was ignored and why. Passwords in the command are redacted. The body is the crontab itself, as `text/plain`. Without…

• get_endpoint

  Status of one endpoint (use the endpoint token if you have it). The monitor token only reads: it lets you put the state on a third-party dashboard without handing over the owner's credential. With a schedule it is here that…

• delete_endpoint

  Removes the owner's endpoint.

• list_events

  Latest ingest pings.

• ping_ingest

  Simulates the cron: GET on /in/:id. No credential on purpose — the caller is a cron, and the ID is already the secret.

• signal_start

  Says the run STARTED. Does not clear the dead-man clock: a routine that starts and hangs still becomes a miss. The next success records the duration. `start` is not proof of life: it does not move `last_event_at` and does not clear the…

• signal_fail

  Record a failed run. The next five-minute check sends the alert with reason fail. The monitor's alert_repeat_sec controls repeated alerts; the default is 24 hours. Failing is not proof of life either: the clock keeps running. The ingest…

• signal_exit_code

  The shell exit status: 0 behaves like a ping, 1-255 record the code as a failure. `curl -fsS $ORIGIN/in/ID/$?` at the end of a script is the whole integration. `0` behaves exactly like a plain ping; 1 to 255 record the code and leave the…

• ingest_key

  Returns (minting the first time) the key for /in/<key>/<slug>, where a ping creates its own monitor inside the free tier. Instruments a whole fleet with no setup call per job. One key per owner. The key survives signing in: the crontab…

• ingest_key_rotate

  Rotates the ingest key; the previous one stops creating monitors. Existing ones keep working. Monitors already created keep working — rotating only revokes the power to create new ones.

• ping_slug

  Create a monitor on its first check-in. The same slug uses the same monitor. A rejected creation writes no monitor or event. The slug becomes the monitor name and its identity: the same slug always means the same monitor, so a retry never…

• signal_slug

  Send start, fail or an exit code by name, with the ingest key; the first signal of a new name creates its monitor. The same signals as `/in/:id/start`, `/in/:id/fail` and `/in/:id/:exit_code`, for a fleet that only knows the ingest key…

• status_feed_url

  Public URL (JSON and RSS) with the status of all the owner's endpoints. The feed token only reads status: it does not create, change or delete. Whoever has the link sees the dashboard — treat it as a secret.

• status_feed_rotate

  Rotates the status feed token; the previous URL stops working.

• list_templates

  Ingest snippets and the JSON HookPulse POSTs on a miss. It exists so nobody guesses the alert format: `miss_json` and `recovery_json` here are the same bodies that arrive at your `alert_url`. Slack and Discord receive only the field they…

• contact

  Write to the people behind the product: a question, or a sponsorship/partnership/advertising proposal. One route for a question and for a sponsorship, partnership or ad proposal (`tipo`, with the placements of `GET /api/partners`). One…
