Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs conv_update_topic safely

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

conv_update_topic Rate-limited

conv_update_topic 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.
