AnyHook

Generate a webhook request with a valid signature for Stripe, GitHub, or Slack. If targetUrl is provided, the request is POSTed there and the response is returned.

Verify a webhook signature against a secret. Supports 19 providers including stripe, github, shopify, slack, discord, linear, vercel, paddle, hubspot, and paypal.

List webhook providers AnyHook can mock, along with the event types available for each.

Zero-config bootstrap: creates a free ephemeral relay endpoint + API key with no signup. Returns inbound_url (receives webhooks immediately), api_key, and claim_url. This MCP session auto-connects to the new account; remote tools work right after. Endpoint expires in 7 days unless claimed.

List apps in your AnyHook account with inbound URLs, sources, and destination URLs.

Every AnyHook app is also an email inbox: mail sent to {user}.{app}@anyhook.net becomes an event (type email.received) you can read with anyhook_events. Returns the address and webhook URL for one of your apps. No account yet? anyhook_quickstart returns an inbox_address directly.

Create a new app with a name, provider source, and (optionally) destinations. Returns the inbound URL.

Re-send a stored event to its destinations. Replay does NOT consume monthly event quota — safe to call repeatedly while debugging.

Show events for the given app that have not successfully reached any destination (failed or still retrying).

Re-send every failed event for the given app slug. Useful after fixing a downstream bug to recover queued work.

List webhook events (most recent first). Uses your AnyHook account when connected (via ANYHOOK_API_KEY or anyhook_quickstart), otherwise the local in-memory store.

Full detail for one event: source, type, status, delivery summary. Account or local store.
