RECOMMENDED RULE

The rule that runs collab_session_open safely

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

collab_session_open Rate-limited

collab_session_open 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.
