THE RISK

Why crow_project_stats needs a policy

This tool queries and retrieves statistical information from the project database. It performs a read-only operation that does not create, modify, delete, or execute any external actions. The blast radius of misuse is minimal, as an AI agent could only over-query for performance impact, not compromise data integrity or trigger unintended operations.

From the tool's definition Tool name contains 'stats' and description states 'Get statistics about the project database' — a retrieval operation with no modification or side effects.

POLICY

How to control crow_project_stats

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

policy.json

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

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