A webhook inbox for agents: one call returns a live URL. Mock, verify, inspect and replay.
AnyHook gives an assistant a webhook inbox: create apps with live inbound URLs, inspect and replay events, mock and verify signed payloads.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
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.anyhook%2Fanyhook/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.Add this to your client's mcpServers config.

}An MCP server that gives AI agents eyes on webhooks, inspect events, replay deliveries, mock signed payloads, create apps. Designed for the 45-second AI handler workflow.
Apache 2.0 · npm i -g anyhook-mcp
A public webhook URL that forwards to your machine, with no account:
stripe.webhooks.constructEvent and friends work as they do in production.listen 3000/api/webhooks sets the path. With ANYHOOK_API_KEY set it uses that account, and --app <slug> picks the app. Needs Node 22 or newer.
It is for webhooks, not a general tunnel. The sender gets its answer from AnyHook, so your server's response goes to the event log rather than back to the sender. To expose a whole site, use ngrok or Cloudflare Tunnel.
Connect the hosted endpoint instead of running anything: add https://anyhook.net/mcp
to Claude Code, claude.ai, Codex or VS Code and sign in through the browser, no key
to copy. Steps for each app: https://anyhook.net/mcp.
No API key needed to start:
Then ask your agent to run anyhook_quickstart, it creates a free relay
endpoint + API key instantly (no signup), and this MCP session auto-connects.
All account tools (events, replay, apps) work immediately. The response includes
a claim_url to keep the endpoint permanently; unclaimed, it expires in 7 days.
It is a new endpoint, not an account you already have.
Drop this MCP server into Claude Desktop / Cursor / Claude Code and your agent can:

setup handshakes automatically: Meta's GET carrying hub.mode=subscribe gets its
hub.challenge echoed back, even before the app is configured, so the URL can be
registered in the Meta App Dashboard first and wired up after.
Two modes:
Get an API key from https://anyhook.net/dashboard/settings. Keys start with ahk_live_.
Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
Restart Claude Desktop. The tools appear under the hammer icon.
Open Settings → MCP → Add new MCP server. Or edit ~/.cursor/mcp.json:
Or add the same mcpServers entry to your project's .mcp.json.
The same server is hosted at https://anyhook.net/mcp (streamable HTTP,
stateless). Claude Code, claude.ai, Codex and VS Code sign in through the
browser (OAuth), no key to copy: https://anyhook.net/mcp has the steps for
each. Any other client sends Authorization: Bearer ahk_live_... with a key
from the dashboard:
The endpoint has no anyhook_quickstart: that tool exists only in local mode.
Skip the env var:
The agent gets anyhook_mock, anyhook_verify, anyhook_providers, anyhook_simulate, anyhook_events (against memory store), and anyhook_inspect (against memory store). Useful for "generate me a signed Stripe payment_intent.succeeded and POST it to localhost:3000" flows during local dev.
Triage a failing endpoint:
"Show me undelivered events for the
stripe-prodapp from the last hour, then replay them."
The agent calls anyhook_undelivered then anyhook_replay for each, surfacing the responses inline.
Create an app for a new integration:
"Make a new AnyHook app called
replicate-video-jobs, sourcegeneric, point it athttps://my-app.vercel.app/api/replicate-callback."
Calls anyhook_apps_create, returns the inbound URL you paste into Replicate.
Sanity-check a signature failure:
"Here's an inbound payload from Stripe that AnyHook is rejecting. Verify the signature manually with secret
whsec_xxx."
Calls anyhook_verify with the supplied headers + body + secret, returns valid: false plus the failure reason.
Mock a webhook for local testing:
"Generate a Stripe
payment_intent.succeededevent and POST it to http://localhost:3000/api/webhooks/stripe."
Calls anyhook_mock with targetUrl set; returns the request that was sent + your handler's response.
AI agents have been blind to their own webhook infrastructure. They can write the integration code, but once an event misbehaves in production they can't see it, you tell them what happened. With this MCP server, Claude / Cursor can read the actual event log, replay deliveries, debug signature failures, and even spin up new apps. It closes the loop between writing webhook code and operating it.

Mock a webhook
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.
dataeventrequiredsecretproviderrequiredtargetUrlVerify a webhook signature
Verify a webhook signature against a secret, for every source the AnyHook edge verifies, including stripe, github, shopify, slack, line, discord, linear, vercel, paddle, hubspot, paypal and xero.
bodyrequiredsecretrequiredheadersrequiredproviderrequiredrequestUrlList supported providers and event types
List webhook providers AnyHook can mock, along with the event types available for each.
Takes no parameters.
List your AnyHook apps
List apps in your AnyHook account with inbound URLs, sources, and destination URLs. Check isActive: an inactive app's inbound URL answers setup handshakes but acknowledges and discards event POSTs (202, reason app_inactive) instead of relaying them. Destination signing secrets are redacted to has_signing_secret plus a 4-char hint; a new secret in plaintext comes only from rotating it. An app whose slug was changed lists its former URLs under legacyInboundUrls; those still route to it.
Takes no parameters.
Get this app's email inbox address
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.
appCreate a new AnyHook app
Create a new app with a name, provider source, and (optionally) destinations. Returns the inbound URL. The app is active immediately. Created WITHOUT destinations it still receives and LOGS every event (inspect-only), it just delivers nowhere until a destination is added (PATCH /api/v1/apps/{slug} with {"destinations": [...]}).
namerequiredsourcerequireddestinationsConnect Stripe or GitHub with one key
Wire a provider to AnyHook in one call: give a Stripe or GitHub key and AnyHook registers the app's inbound URL as a webhook at the provider, saves the signing secret it yields, and turns on signature verification at the edge. The provider is read from the key; the key is used once and not stored. Without appSlug a new app is created (and removed again if the provider refuses the key). Re-running replaces the registration instead of duplicating it. GitHub sends a signed ping immediately, so the first event appears within seconds. Add a destination afterwards (PATCH /api/v1/apps/{slug}) to forward events; until then they are received and logged.
targetappSlugprovider_keyrequiredReplay an event
Re-send a stored event to its destinations. Replays sit outside the monthly event quota but within a daily replay limit per plan and the monthly compute allowance (anyhook_usage), and replaying an event that was held for quota bills it as a new event. The destination does run its handler again: a receiver that is not idempotent will process the event twice while debugging.
idrequiredList undelivered events for an app
Show events for the given app that have not successfully reached any destination (failed or still retrying).
limitappSlugrequiredBulk-replay an app's failed events
Re-send an app's failed events after the destination is fixed, oldest first: by default those received in the last 24 hours, at most 50 per call (since and limit change both; limit goes up to 100). Events held by an open circuit are included. An event replayed once is not selected again, so a second call continues with the rest. The result lists what was replayed, what was skipped and why, and more: true while failed events are still waiting. Replays count against the plan's daily replay limit.
limitsinceappSlugrequiredRead an app's code handler
The code that runs on this app's events: its source, the names of its secrets (never the values), whether events are reaching it, and runs used this month against the plan's limit.
appSlugrequiredDeploy code that runs on an app's events
Save a handler that runs on every event this app receives, in an isolated sandbox, with AnyHook's retries and replay around it: no server of your own. Each run's console output and return value are stored as that delivery's response (anyhook_inspect shows them). It can also run on a cron schedule. Pro and Scale; runs are capped per month with no overage, retries, test runs and schedule firings each count, and each run and package install is charged to the monthly compute allowance (anyhook_usage shows both). Test it with anyhook_code_test before real events arrive.
coderequiredappSlugrequiredenabledsecretsscheduleRun an app's code on a stored event
Run the saved handler now and return its logs, return value and duration: on a stored event (the latest when event_id is omitted) or on a body you give. Counts as a run. Nothing is delivered, but whatever the code itself sends does happen.
bodyappSlugrequiredevent_idShow plan limits and usage
What the plan allows and what this account has used of each: events this month (per delivery, large events count per 64 KB), overage, the compute allowance and what used it (retries, replays, waiting on slow destinations, code runs, builds, schedules), API calls today (each tool call that reads or changes the account counts one), code runs and package snapshots, with when each resets. Call it when something answers with a limit, before bulk work such as replay_failed, or when the user asks what they are using.
Takes no parameters.
List recent webhook events
List webhook events, most recent first: id, app, type, status, attempt, destination status code, latency, timestamp. Summaries only, no request headers or body; anyhook_inspect reads one event's payload by the id from here. Uses your AnyHook account when connected, otherwise the local in-memory store.
limitstatusappSlugInspect a specific event
Full detail for one event by id, including the inbound headers and body that anyhook_events omits, plus the destination's response. Payloads can be large and often contain personal data, so fetch one at a time, only when the body is needed. Account or local store.
idrequired100% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
