## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__anyhook__anyhook_code_get` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__anyhook__anyhook_code_deploy` `mcp__anyhook__anyhook_code_test` `mcp__anyhook__anyhook_connect` `mcp__anyhook__anyhook_mock` `mcp__anyhook__anyhook_replay` `mcp__anyhook__anyhook_replay_failed` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (5)

Removes, cancels or revokes something. Claude Code: deny.

### `anyhook_code_deploy`

- The name "anyhook_code_deploy" says "deploy": a word for a change.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `anyhook_code_test`

- The description's first verb is "run": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `anyhook_mock`

- The description's first verb is "generate": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `anyhook_replay`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `anyhook_replay_failed`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

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

## Changes things (5)

Creates or changes something that can be changed back. Claude Code: ask.

### `anyhook_apps_create`

- The name "anyhook_apps_create" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
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": [...]}).
```

### `anyhook_connect`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `anyhook_inbox`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `anyhook_usage`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `anyhook_verify`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (6)

Looks things up and changes nothing. Claude Code: allow.

### `anyhook_apps_list`

- The name "anyhook_apps_list" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `anyhook_code_get`

- The name "anyhook_code_get" says "get": a word for reading.
- Tag private-data: The description's first sentence says "secret": it reads secrets.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `anyhook_events`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List webhook events, most recent first: id, app, type, status, attempt, destination status code, latency, timestamp. Summaries only, no request headers or body — call anyhook_inspect with an id from here to read one event's payload. Uses your AnyHook account when connected, otherwise the local in-memory store.
```

### `anyhook_inspect`

- The name "anyhook_inspect" says "inspect": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `anyhook_providers`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List webhook providers AnyHook can mock, along with the event types available for each.
```

### `anyhook_undelivered`

- The description's first verb is "show": a word for reading.

Description, as the server wrote it:

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