RECOMMENDED RULE

The rule that runs setup_pre_commit safely

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

setup_pre_commit Rate-limited

setup_pre_commit 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.
