Before you connect

The login page asks for your Dead Man's Snitch API key.

Create a key on the API Keys page of your Dead Man's Snitch account (the API needs a paid plan). A separate key for this connection makes it easy to revoke. Your key is used only to call the Dead Man's Snitch API on your behalf; it is never shown to anyone.

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Dead Man's Snitch API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Tools 12

ToolTypeWhat it does
deadmanssnitch_list_snitchesread
List snitches
List the snitches (cron/heartbeat monitors) of the account with status (pending, healthy, failed, errored, paused), interval, alert type, tags and last check-in. Tokens are masked (the token is also the check-in secret); pass the masked token or the name to the other snitch tools. The API has no paging: all snitches come back. Optionally filter by tags (must have all) or status. GET /v1/snitches.
deadmanssnitch_get_snitchread
Get snitch
One snitch with its full details, including the check-in URL (https://nosnch.in/<token>). The check-in URL is a secret: anyone who has it can check in and so silence the alert; share it only where the job runs. GET /v1/snitches/{token}.
deadmanssnitch_create_snitchwrite
Create snitch
WRITE: create a new snitch (monitor). Returns it with its check-in URL (https://nosnch.in/<token>), which the job must call on every run; keep it secret. Fails with 402 when the plan's snitch limit is reached. POST /v1/snitches.
deadmanssnitch_update_snitchwrite
Update snitch
WRITE: change a snitch. Only the fields you pass change. `tags` REPLACES the whole tag list (use deadmanssnitch_add_tags to add) and `alert_email` replaces the alert recipients (an empty list = all team members). Returns the updated snitch with the token masked. PATCH /v1/snitches/{token}.
deadmanssnitch_add_tagswrite
Add tags
WRITE: add one or more tags to a snitch, keeping the existing ones. Returns the snitch's full tag list. POST /v1/snitches/{token}/tags.
deadmanssnitch_remove_tagwrite
Remove tag
WRITE: remove one tag from a snitch (the snitch itself is untouched). Returns the remaining tags. DELETE /v1/snitches/{token}/tags/{tag}.
deadmanssnitch_pause_snitchwrite
Pause snitch
WRITE: pause a snitch, which SILENCES its alerts: a job that stops running goes unnoticed while it is paused. `until` says when alerting resumes: 'healthy' (default: on the next healthy check-in), 'unpaused' (stays paused until deadmanssnitch_unpause_snitch) or a future ISO 8601 time. A snitch that has never checked in (pending) cannot be paused. POST /v1/snitches/{token}/pause.
deadmanssnitch_unpause_snitchwrite
Unpause snitch
WRITE: resume alerting for a paused snitch (safe on a snitch that is not paused). POST /v1/snitches/{token}/unpause.
deadmanssnitch_usage_statusmeta
Usage status (free-tier meter)
Report the caller's current free-tier usage this month: calls used, monthly limit, remaining, and whether the cap is reached. Read-only; does not count against the meter.
deadmanssnitch_request_featuremeta
Request a missing feature
Tell usefulapi that the user needs something the Dead Man's Snitch tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
deadmanssnitch_upgrademeta
Upgrade to Pro (unlimited)
Subscribe to the Pro plan for UNLIMITED Dead Man's Snitch tool calls (the free tier caps monthly usage). Choose monthly ($9/month) or yearly ($90/year — 2 months free) billing. Returns a Stripe Checkout link to open in your browser; after payment your account upgrades automatically. Does not count against the meter.
deadmanssnitch_cancel_subscriptionmeta
Cancel the Pro subscription
Cancel the caller's Dead Man's Snitch Pro subscription at the end of the paid period (no refund for the current period; unlimited calls continue until then, then the free tier applies). Requires confirm: true. Run deadmanssnitch_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

Is this an official Dead Man's Snitch product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Dead Man's Snitch. The server calls the Dead Man's Snitch API with your own Dead Man's Snitch access, so it sees only the data that your account can see.

What do I need to connect?

The login page asks for your Dead Man's Snitch API key. See Before you connect for where to find it.

Do I put my Dead Man's Snitch key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Dead Man's Snitch API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my Dead Man's Snitch credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Dead Man's Snitch API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Dead Man's Snitch.

Can the AI change my Dead Man's Snitch data?

Yes, if you approve it. 6 of the 8 Dead Man's Snitch tools can create or change data. The other 2 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 100 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls, for this Dead Man's Snitch server only. Run deadmanssnitch_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run deadmanssnitch_upgrade: it returns a Stripe Checkout link. To cancel, run deadmanssnitch_cancel_subscription. Pro continues to the end of the paid period.

What if a Dead Man's Snitch tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with deadmanssnitch_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
