THE RISK

Why clear_fast_memory needs a policy

This tool permanently removes all cached/stored query data from the Fast Memory system. While not directly financial or operating on production user data (based on context as a caching layer), it irreversibly destroys a data store.

From the tool's definition 'Clear all queries from Fast Memory' - the verb 'clear' combined with 'all' indicates irreversible deletion of stored data without conditional filtering or undo capability.

POLICY

How to control clear_fast_memory

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

policy.json

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

clear_fast_memory 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 ConnectWise API Gateway 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.
