Overview

AI-generated overview

Remote MCP server for HookPulse, a dead-man switch that alerts when cron jobs, webhooks, backups or scheduled workflows stop checking in.

What you can do
Create and manage monitors for routines, with cron or interval schedules, time zones, grace periods and maximum run durations, plus website uptime monitors and manual site checks with rate limits per host. Import a pasted crontab as a proposal first, then apply it to create monitors in one call. Send start, success, failure or shell exit-code signals, and instrument a fleet with one ingest key where the first check-in of a name creates its monitor. Read monitor state, latest ingest pings and events, and rotate ingest or status feed tokens. Publish a public JSON and RSS status feed, list alert templates, and contact the product team.
When to use it
Use it when you want an assistant to set up or inspect monitoring for scheduled jobs, backups, webhooks or GitHub Actions workflows, and to be alerted by e-mail, Slack or Discord when a routine misses its check-in or fails. Also useful for importing an existing crontab into monitors.
Requirements
A remote Streamable HTTP endpoint; no key is needed to start. A guest token from create_guest is needed to keep access to created monitors unless they are tied to an e-mail. Network access to hookpulse.net, which receives monitor names, schedules and alert destinations over HTTPS.
Before you install
The guest token must be kept, or the monitors become unreachable without an e-mail link. The status feed link is readable by anyone who has it and should be treated as a secret. Ingest keys can create monitors, and rotating one revokes that power. Deleting an endpoint removes it. Monitor metadata is sent to hookpulse.net. Ten monitors are free; e-mail alerts beyond one monitor cost a one-time fee, though the server has no purchase tool.

Installation

In SourceWeft

  1. Open Hookpulse in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/net.hookpulse%2Fhookpulse/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

HookPulse — skill and MCP server for AI agents

[HookPulse]

HookPulse tells you when a cron job, webhook, backup or scheduled GitHub Actions workflow stops running. Each routine gets a check-in link. If the check-in does not arrive by the expected time, or the routine reports a failure, HookPulse sends an alert by e-mail or to a webhook such as Slack or Discord, and it tells you when the routine comes back. This repository packages the HookPulse skill and the connection to its remote MCP server for Claude Code, Codex, Cursor and other agents.

Site: https://hookpulse.net · MCP server: https://hookpulse.net/mcp?checkout=site · Prices: https://hookpulse.net/pricing · API docs: https://hookpulse.net/developers

What your agent can do

  • Create a monitor for a routine, with an interval or a cron schedule, a time zone and an allowed delay.
  • Import a crontab: see the proposed monitors first, then create them in one call.
  • Give each run a start, a success or a failure signal, with the shell exit code.
  • Instrument a whole fleet with one setup key: the first check-in of each name creates its monitor.
  • Read the state of every monitor, the latest check-ins and the public status page.

Try: "Import my crontab into HookPulse and show me what it would create." or "Create a monitor for the nightly backup that runs at 03:00 São Paulo time."

GitHub Actions

A scheduled workflow gets a monitor with one step and no secret. The job's identity token tells HookPulse which repository and workflow it is; the first run creates the monitor with the workflow's schedule:

yaml
permissions:  contents: read  id-token: writejobs:  backup:    runs-on: ubuntu-latest    steps:      - run: ./backup.sh      - uses: wrpbr/hookpulse-action@v1        if: always()        with:          status: ${{ job.status }}

See wrpbr/hookpulse-action for alerts and options. Without changing any workflow, install the HookPulse GitHub App: a missed or failed scheduled run opens an issue in the repository, and the next good run closes it.

Install

Claude Code, as a plugin with the skill and the MCP server:

/plugin marketplace add wrpbr/hookpulse/plugin install hookpulse@hookpulse

Any agent that reads Agent Skills (Claude Code, Codex, Cursor, OpenCode and others):

bash
npx skills add wrpbr/hookpulse

Only the MCP server (remote, Streamable HTTP, no key needed to start):

bash
claude mcp add --transport http hookpulse 'https://hookpulse.net/mcp?checkout=site'   # Claude Codecodex mcp add hookpulse --url 'https://hookpulse.net/mcp?checkout=site'               # Codex
json
{ "mcpServers": { "hookpulse": { "url": "https://hookpulse.net/mcp?checkout=site" } } }

The JSON above goes in .cursor/mcp.json for Cursor and in the MCP settings of most other clients. The GitHub Copilot coding agent takes it in the repository settings, under Copilot → MCP servers, with "type": "http" and the tools you allow.

Price

Ten monitors are free, and check-ins have no charge. E-mail alerts on one monitor are free; e-mail alerts on each additional monitor cost a one-time fee. Alerts to webhooks have no alert charge. You buy credit on the site, and nothing renews automatically. The plugin never pays: with checkout=site, the MCP server has no purchase tool and no payment argument. The current prices are at https://hookpulse.net/pricing.

What the plugin sends

The skill tells the agent to call the HookPulse API at hookpulse.net. The MCP server also runs at hookpulse.net. The names, schedules and alert destinations of your monitors go to hookpulse.net over HTTPS. The plugin runs no local program and reads no local file; the crontab import reads only the text you paste.

Em português

O HookPulse avisa quando uma rotina agendada, um webhook, um backup ou um workflow agendado do GitHub Actions para de rodar. Cada rotina ganha um link de check-in; se ele não chega no horário, ou se a rotina avisa uma falha, o alerta sai por e-mail ou por webhook. Este repositório traz a skill e a conexão com o servidor MCP remoto. Instale com os comandos acima. Dez monitores são grátis. Os preços estão em https://hookpulse.net/pricing.

create_endpoint

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: HookPulse calls `check.url` every `interval_sec` (default 300) and alerts when it goes down — two failed checks in a row, one minute apart, from a server whose own connection is proven — and when it answers again. `{"check":{"url":"https://example.com/"}}` is enough; the name defaults to the host. A site has no `cron`, no `max_duration_sec` and no ingest URL. This response is the only one that shows the monitor's `token` and the `templates` — keep them. A miss alerts at most once per 24h — or per `alert_repeat_sec`, or per interval, whichever is longer. Send `cron`+`tz`+`grace_sec` instead of `interval_sec` for a real schedule: a 03:00 backup is late at 03:01:30, not 24 hours later. `max_duration_sec` catches the other failure: a run that starts and hangs, which plain silence detection only notices at the next scheduled time.

Parametersnametagscheckrequiredalert_toalert_urlguest_tokenrequiredinterval_secpaused_until

check_site

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 are looking at it. After that, the state and the alerts come from the check that runs every minute.

Parametersidrequiredguest_tokenrequired

list_sites

List sites

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

Parametersguest_tokenrequired

import_crontab

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 `?apply=1` **nothing is written**: you get the proposal — what would become a monitor, what was ignored and why, and what still fits in the free tier. With `apply=1` it is all or nothing, under the same rules as `POST /api/endpoints`. Comments, variables and `@reboot` are ignored (there is no way to know when to expect a reboot); `@daily` and friends become the equivalent expression. The command becomes the monitor name, with passwords and tokens redacted first — the name travels in the alert e-mail, in the public dashboard and in the badge.

Parametersapplycrontabrequiredguest_tokenrequired

get_endpoint

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 `next_expected_at` says when the next run is due.

Parametersidrequiredtokenguest_token

delete_endpoint

Delete endpoint

Removes the owner's endpoint.

Parametersidrequiredguest_tokenrequired

list_events

List events

Latest ingest pings.

Parametersidrequiredtokenguest_token

ping_ingest

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.

Parametersidrequired

signal_start

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 miss counter, so a routine that starts and hangs still becomes a miss at the right time. The next success closes the run and records `last_duration_ms` — pass `?rid=` on both ends when runs can overlap, or the duration is measured against the wrong start. With `max_duration_sec` set on the monitor, a run left open past that ceiling alerts with `reason: "too_long"` on the next 5-minute check. Works by GET or POST.

Parametersidrequired

signal_fail

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 never sends e-mail and never calls out — it records `alert_pending` and the cron turns it into an alert with `reason: "fail"` within 5 minutes, under the same one-per-24h cap. Works by GET or POST.

Parametersidrequired

signal_exit_code

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 failure for the cron.

Parametersidrequiredexit_coderequired

ingest_key

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 you deployed keeps working.

Parametersguest_token

ingest_key_rotate

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.

Parametersguest_token

ping_slug

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 creates a second one. Normalised to lowercase, `[a-z0-9-]`, 40 chars. Works by GET or POST.

ParametersslugrequiredingestKeyrequired

signal_slug

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: the job sends its name, not the monitor id. The first signal of a new name creates the monitor, with the same rules and the same `cron`, `tz` and `grace_sec` as the plain ping by name.

ParametersslugrequiredsignalrequiredingestKeyrequired

status_feed_url

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.

Parametersguest_token

status_feed_rotate

Status feed rotate

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

Parametersguest_token

list_templates

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 read.

Takes no parameters.

contact

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 message every 10 seconds per network: one that arrives sooner waits its turn and then goes out — no error. The message reaches the team by e-mail, with `email` as the reply address. For voice, send multipart/form-data: `dados` is this JSON (up to 32 KiB), and `audio` is one WebM, Ogg or M4A audio file (up to 2 MB). Audio can replace message. The browser records up to two minutes. Audio is attached to the owner's e-mail.
