THE RISK

Low Risk

Why find_todos needs a policy

This tool performs a search/query operation across a manuscript to identify and return TODO markers. It retrieves data about the document's status markers without modifying the document, executing code, or causing side effects. The blast radius of misuse is minimal—an AI agent could only learn about incomplete sections, which presents no security or operational risk.

From the tool's definition Tool extracts and lists TODO/FIXME/DRAFT markers from markdown documents. The description indicates it 'extracts' (retrieves) markers with no modification or execution of external operations.

POLICY

How to control find_todos

PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Writer's Aid MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for find_todos:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "find_todos": {}
  }
}

find_todos is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
