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_copy

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

    Matched text

    annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "check_copy" says "copy": a word for a change.

  • Warncheck_code

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

    Matched text

    annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The input takes a statement or command to run (input.code), which can change anything it can reach.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

      What this check looks for
    Description, as the server wrote it
    Check a source file or diff for AI 'tells' left in comments: narrating fulfilling a request instead of describing the code ("as requested," "I've added," "here's the updated version") and hedge words. These reveal there was a conversation behind the change that a later reader has no access to. Call this before committing or shipping code an agent wrote.

      Matched text

      annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "check_copy" says "copy": a word for a change.

      What this check looks for
    Description, as the server wrote it
    Check marketing or outreach copy (an email, a landing-page draft, a pitch, a social post) for the tells that make it read as AI-generated: cliché vocabulary (delve, unlock, empower, seamlessly integrate, etc.), negative-parallel framing ("not just X, but Y"), hedge words, heavy em-dash use, and diagnosing a problem with no fix in the same breath. No page or markup needed, just the text. Call this before sending copy to a human.

    Why it is in this group

    • 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
    Check a page's HTML/CSS/copy/interaction for the patterns that make AI-generated work read as generic: default fonts, soft tech gradients, pill+arrow buttons, eyebrow labels, a composition with no real width/background variation across sections, uniform card grids, copy tells (AI vocabulary, negative-parallel framing, hedge words, heavy em-dash use), and experience gaps (a diagnosis with no next step, dead-end links). Every finding includes a concrete fix. Call this before presenting UI to a human.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: true

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 1.0.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http designcheck https://designcheck.allthepossibles.com/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": [],
    "ask": [
      "mcp__designcheck__check_design",
      "mcp__designcheck__check_copy",
      "mcp__designcheck__check_code"
    ],
    "deny": []
  }
}

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 designcheck. Review it before you use it.
