THE RISK

Low Risk

Why listTodos needs a policy

The tool retrieves and displays existing todo items without creating, modifying, deleting, or executing any operations. It is a simple read query with minimal blast radius even if misused by an agent.

From the tool's definition Tool name is 'listTodos' and description states 'List all tasks in your todo list' — a pure retrieval operation with no side effects.

POLICY

How to control listTodos

PolicyLayer is an MCP gateway — it sits between your AI agents and Cloudflare MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for listTodos:

policy.json

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

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

Create a free account and register Cloudflare MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
