Why microcms_get_list_meta needs a policy

This tool retrieves metadata about list contents from a CMS API. It performs a read-only query operation with no side effects—it does not create, modify, delete, or execute external operations. The blast radius of misuse is minimal; an AI could at worst retrieve unintended metadata, but cannot alter or destroy data. This is clearly a Read category tool.

From the tool's definition Tool name contains 'get' and description states 'Get a list of contents with metadata from microCMS Management API'. The verb 'get' and the retrieval-focused purpose indicate data retrieval without modification.

POLICY

How to control microcms_get_list_meta

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_list_meta:

policy.json

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

microcms_get_list_meta 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.
