Why get_file_watcher_status needs a policy

This tool retrieves monitoring status and statistics about a file watcher service. It performs a query operation that returns information without creating, modifying, deleting, or executing anything. The minimal blast radius of misuse is returning unwanted status information, which is a characteristic of Read category tools.

From the tool's definition Tool name is 'get_file_watcher_status' and description states 'Get file watcher service status and statistics.' The verb 'Get' and the focus on retrieving status information and statistics indicate read-only data retrieval with no side effects.

POLICY

How to control get_file_watcher_status

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

policy.json

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

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

How do I block get_file_watcher_status completely? +

Set action: deny in the PolicyLayer policy for get_file_watcher_status. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides get_file_watcher_status? +
