RECOMMENDED RULE

The rule that runs comment_issue safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 4bis Relay Showcase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For comment_issue, this is the rule to start with:

comment_issue Rate-limited

comment_issue 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.
