RECOMMENDED RULE

The rule that runs web.url.shorten safely

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

web.url.shorten Rate-limited

web.url.shorten 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.
