## Findings

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

```untrusted-server-text
The description names a tool "check_file" that this server does not list.

description: "...access — the wsc-mcp npm package adds a check_file tool for local files. It only reports issues..."
```

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The description's first verb is "remove": a word for removing or ending something.
```


## Deletes or cancels (1)

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

### `fix_duplicates`

- The description's first verb is "remove": a word for removing or ending something.
- 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
Remove duplicate adjacent words (case-insensitive, including across line breaks) and return the cleaned text plus the list of words that were removed. Read-only with no side effects: the fix is returned in the response, nothing is written anywhere. Use after check_text reports duplicate words; other issue types are report-only and have no auto-fix.
```

## Only reads (2)

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

### `check_text`

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

Description, as the server wrote it:

```untrusted-server-text
Analyze text for writing style issues: weasel words, passive voice, duplicate words, long sentences, nominalizations, hedging, filler adverbs, and research-cited AI tells. Read-only and stateless — text is analyzed in memory on the hosted server and never stored. Returns a plain-text report with each issue's line and column, the matched text, surrounding context, and the reason for AI tells; texts over 100,000 characters return an error message. This hosted server has no filesystem access — the wsc-mcp npm package adds a check_file tool for local files. It only reports issues — to auto-remove duplicate words, follow up with fix_duplicates.
```

### `list_word_lists`

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

Description, as the server wrote it:

```untrusted-server-text
Return every detector word/phrase list with its entry count, config key, and sample entries, plus a link to the full browsable library. Read-only, takes no parameters, and returns the same catalog for a given release. Use it to see what the detectors match before tuning a config for check_text; not needed for ordinary checking.
```

## Claude Code permissions
