## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `verify_email`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Verify whether ONE email address is deliverable. Checks syntax, MX, SMTP, catch-all, disposable, free-provider and role detection, and returns a 0-100 quality score. Charges 1 Fox Credit per uncached email.
```

### `verify_emails`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Bulk-verify a LIST of email addresses. Submits the whole list, waits for completion, and returns one result per email (same fields as verify_email). Best for cleaning lead lists. Charges 1 Fox Credit per email. Large lists that don't finish quickly return a jobId to poll with get_job.
```

## Only reads (4)

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

### `find_email`

- The name "find_email" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find ONE person's business email from their name and company domain. Generates ~50 permutations and SMTP-verifies each, waits for the result, and returns the best match (or not_found). Charges 10 Fox Credits per find.
```

### `find_emails`

- The name "find_emails" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Bulk-find business emails for a LIST of contacts (name + company domain each). Submits the list, waits for completion, and returns the found email per contact. Up to 1000 contacts. Charges 10 Fox Credits per contact. Large lists that don't finish quickly return a jobId to poll with get_job.
```

### `get_credits`

- The name "get_credits" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the current Fox Credit balance for the Verifox account tied to the API key. Free — no credits charged. Use it to check remaining balance before a big verify/find run (verify = 1 credit/email, find = 10 credits/contact).
```

### `get_job`

- The name "get_job" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Check an async job started by verify_emails, find_email, or find_emails. Returns results if finished, otherwise the current status. Use the type shown in the submitting tool's response.
```
