RECOMMENDED RULE

The rule that runs upload_file_route safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Elevenlabs, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For upload_file_route, this is the rule to start with:

upload_file_route Rate-limited

upload_file_route stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Elevenlabs, apply this rule, and every upload_file_route call is checked against it from then on.
