THE RISK

Critical Risk

Why fl_clear_request_queue needs a policy

Clearing a pending queue removes data that cannot be recovered once purged. While it doesn't delete already-executed notes, discarding queued requests is an irreversible operation (the pending requests are gone permanently), placing it in the Destructive category. Severity is medium since it only affects queued/pending operations, not already-committed state.

From the tool's definition 'Clear any pending note requests without executing them' — irreversibly discards queued requests

POLICY

How to control fl_clear_request_queue

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

policy.json

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

fl_clear_request_queue 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 FL Studio 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.
