## Findings

- **warn** Annotations that disagree with the tool in `check_link` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "check_link" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "check_link" says "link": a word for a change.
```


## Changes things (3)

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

### `check_breach`

- 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
Checks whether an email address appears in known data breaches. Provide `email`. Returns the number of breaches found with the named sources behind each; a count of zero means no breaches were found in the corpus, not that the address is safe. Read-only: it only looks up breach records. Requires the RELAYSHIELD_API_KEY environment variable; without it, the tool returns setup instructions instead of calling the API.
```

### `check_email`

- 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
Scores a suspicious email for phishing signals from its parsed fields. Provide any of: from_address, from_name, reply_to, return_path, subject, body_text, and links (up to 25). Returns a risk level and score with the specific flags behind them; links in the email are also checked against RelayShield's threat-intelligence corpus. A verdict of unknown means nothing conclusive was found; this tool never reports an email as safe.
```

### `check_link`

- The name "check_link" says "link": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Checks one URL, or up to 25 URLs in a single call, against RelayShield's threat-intelligence corpus for known phishing, malware, and scam abuse. Provide either `url` (a single http:// or https:// link) or `urls` (an array of up to 25 links). Returns a per-link verdict of FLAGGED or unknown with the reasons behind each verdict, plus counts of checked, flagged, and incomplete links. A verdict of unknown means nothing is known against the link; this tool never reports a link as safe.
```

## Only reads (1)

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

### `check_wallet`

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

Description, as the server wrote it:

```untrusted-server-text
Returns a read-only risk assessment of a cryptocurrency wallet address. It never moves funds or initiates transactions. Provide `address`; the chain (EVM, Solana, TON, or Bitcoin) is detected from the address format automatically. Returns a risk level of CRITICAL, HIGH, MEDIUM, LOW, or unknown, with the specific sanctions, scam, drainer, and phishing flags behind it. A verdict of unknown means nothing is known against the address; it does not mean the address is safe.
```
