Why crow_reset_refcounts needs a policy

This tool acts as a kill switch that clears all lifecycle reference counts, which is an irreversible reset of internal state tracking. Misuse could disrupt active sessions, connections, or provider lifecycle management across all integrations, potentially causing cascading failures in an AI-powered project management system with 20+ integrations.

From the tool's definition 'Operator kill switch: clear all lifecycle refcounts' — explicitly clears/resets persistent state; 'reconcile against live provider health' suggests irreversible state modification

POLICY

How to control crow_reset_refcounts

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_reset_refcounts:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "crow_reset_refcounts"
  ]
}

crow_reset_refcounts disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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.
