Findings

Matches of fixed checks, with the text they matched.

1 warn
  • Warninstall_local

    The server marks "install_local" 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 "install_local" says "install": a word for a change.

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

Claude Code permissions

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

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__ops-guardrails__list_checks",
      "mcp__ops-guardrails__sample_findings",
      "mcp__ops-guardrails__products"
    ],
    "ask": [
      "mcp__ops-guardrails__install_local"
    ],
    "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 ops-guardrails. Review it before you use it.
