Why get_tool_catalog needs a policy

This tool queries and returns a catalog of tools and workflows without modifying, executing, or deleting any data. It is purely informational and has minimal blast radius if misused by an agent—at worst, an agent would receive tool recommendations it should not have access to, but no device control, data destruction, or financial impact would occur.

From the tool's definition Tool name 'get_tool_catalog' and description 'Return the recommended everyday tools, advanced tools, and workflow' indicate a retrieval operation with no side effects. The verb 'Return' and 'get' prefix confirm data querying.

POLICY

How to control get_tool_catalog

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

policy.json

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

get_tool_catalog 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 米家 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.
