Why microcms_get_api_list needs a policy

This tool only queries and returns information about available API endpoints from the microCMS system. It performs a read-only operation that retrieves metadata without creating, modifying, deleting, or executing any external operations. The blast radius of misuse is minimal since it only exposes API endpoint names and types, which is generally non-sensitive discovery information.

From the tool's definition Tool name contains 'get' and description states it 'Get list of all available APIs' and 'Returns API name, endpoint, and type' — retrieves metadata about available APIs with no modification or side effects.

POLICY

How to control microcms_get_api_list

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

policy.json

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

microcms_get_api_list 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 microCMS MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
