Why get_link needs a policy

This tool performs data retrieval only—it fetches information about a link by identifier without modifying, deleting, executing, or creating resources. The verb 'Retrieve' and the passive scope ("details of a specific link") confirm read-only behavior. Given the server's financial context (AP2 payment protocol), the link data is likely metadata rather than transactional, further supporting a low-risk classification.

From the tool's definition Tool name 'get_link' and description 'Retrieve details of a specific link by ID' indicate a query operation with no side effects.

How to control get_link

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 get_link:

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

get_link 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.
