2 checks matched something in the tool definitions. No finding is not a safety guarantee. How the checks work.

Findings

Matches of fixed checks, with the text they matched.

2 warn
  • Warncheck_text

    The description names a tool "check_file" that this server does not list.

    Matched text

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

    What this check looks for
  • Warnfix_duplicates

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

    Matched text

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

    Why it is in this group

    • 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.

    • Warn

      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.

      What this check looks for
    Description, as the server wrote it
    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.

    Why it is in this group

    • The description's first verb is "analyze": a word for reading.

    Findings

    • Warn

      The description names a tool "check_file" that this server does not list.

      Matched text

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

      What this check looks for
    Description, as the server wrote it
    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.

    Annotations the server declares

    • readOnlyHint: true
    • openWorldHint: false
  • list_word_listsReturn every detector word/phrase list with its entry count, config key, and sample entries, plus a link to the full browsable library.No findings

    Why it is in this group

    • The name "list_word_lists" says "list": a word for reading.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • readOnlyHint: true
    • openWorldHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Install

Pinned to version 2.2.2. Values in angle brackets are yours to fill in.

claude mcp add --transport http wsc https://wsc.theserverless.dev/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__wsc__check_text",
      "mcp__wsc__list_word_lists"
    ],
    "ask": [],
    "deny": [
      "mcp__wsc__fix_duplicates"
    ]
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as wsc. Review it before you use it.
