## Findings

- **warn** Mentions of other tools or servers in `uidwatch_signup` ([tool-shadowing](https://anlyon.dev/methodology#tool-shadowing))

```untrusted-server-text
The description contains "every other tool", wording about other tools or servers.

```


## Deletes or cancels (3)

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

### `watchlist_remove`

- The name "watchlist_remove" says "remove": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Remove one entry from the watchlist; name its group if it has one.
```

### `watchlist_replace`

- The name "watchlist_replace" says "replace": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Replace the whole watchlist with these entries, e.g. to sync it from an ERP every night: entries missing from items are removed, entries that stay keep their date. UIDs are accepted as CHE-123.456.789, CHE123456789 or with MWST/TVA/IVA; the check digit must match. Each entry may carry your reference (e.g. a customer number) and a group (e.g. the client a debtor belongs to). All or nothing: one invalid UID rejects the call with every problem listed. New entries get an initial check of the history in the gazette.
```

### `webhook_delete`

- The name "webhook_delete" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Delete a webhook endpoint; no more events are posted to it.
```

```untrusted-server-text
A Stripe Checkout link for the subscription: CHF 33 per month per package of 2500 entries, 1 to 10 packages, cancel monthly. A person, or an agent with its own payment method, opens the link and pays there.
```

### `uidwatch_signup`

- The description's first verb is "create": a word for a change.
- Findings: warn tool-shadowing

Description, as the server wrote it:

```untrusted-server-text
Create a UIDWatch account and get its API key. The key is shown only in this answer: keep it and send it as "Authorization: Bearer <key>" in the configuration of the MCP client, which every other tool needs. accept_terms must be true: it accepts the terms of service (https://uidwatch.tollwyn.com/terms?via=mcp-registry), including the data processing terms in section 8, on behalf of the business that signs up. The trial lasts 30 days and watches 20 entries until a person confirms the email address from the mail UIDWatch sends, then 2500. via is an optional partner id; without one the account counts as signed up through MCP.
```

### `watchlist_add`

- The name "watchlist_add" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Add entries to the watchlist, or change the reference of entries already on it. UIDs are accepted as CHE-123.456.789, CHE123456789 or with MWST/TVA/IVA; the check digit must match. Each entry may carry your reference (e.g. a customer number) and a group (e.g. the client a debtor belongs to). All or nothing: one invalid UID rejects the call with every problem listed. New entries get an initial check of the history in the gazette.
```

### `webhook_create`

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

Description, as the server wrote it:

```untrusted-server-text
Add a webhook endpoint (https on a public address, at most 5): every new event of the chosen kinds (default: all) is posted to it as JSON, signed with HMAC-SHA256 in the UIDWatch-Signature header. The signing secret is returned only in this answer.
```

### `webhook_test`

- The description's first verb is "post": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Post a sample event marked "test": true to a webhook endpoint now and tell how it answered (10 per minute).
```

## Only reads (4)

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

### `account_status`

- The name "account_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The account: plan (trial, monitor or paused), whether the list is monitored, the limit and usage in entries, the end of the trial, whether the email address is confirmed, and last_scan_at, the last successful check of the gazette.
```

### `events_list`

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