Why list_items needs a policy

This tool retrieves and queries bank connection data without creating, modifying, deleting, or executing operations. It is a straightforward GET endpoint that returns information. While bank connection data is sensitive, the read-only nature and informational purpose place it in the Read category with low severity, as exposure does not directly cause financial loss or irreversible damage by itself.

From the tool's definition Tool name 'list_items' and description 'List bank connections (items) owned by the application' with HTTP method GET /items indicates a read-only retrieval operation with no side effects.

How to control list_items

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for list_items:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_items": {}
  }
}

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

  1. Create a free account and register Mcp Ap2 — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
