RECOMMENDED RULE

The rule that runs import_from_sidecar safely

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

import_from_sidecar Rate-limited

import_from_sidecar 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.
