Why refresh_pro_tools_index needs a policy

This tool performs a synchronization of local cache state with the current Pro Tools timeline state. Synchronization operations are read-heavy—they fetch the current state to update a local representation. No data is modified in Pro Tools, no code is executed on behalf of the user, and no destructive or financial actions occur.

From the tool's definition Tool name 'refresh_pro_tools_index' and description 'Synchronizes the local cache with the Pro Tools timeline' indicate a cache synchronization operation that queries/retrieves state from Pro Tools without modifying data or executing arbitrary operations.

POLICY

How to control refresh_pro_tools_index

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

policy.json

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

refresh_pro_tools_index 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 Pro Tools 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.
