RECOMMENDED RULE

The rule that runs memory_bookmark safely

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

memory_bookmark Rate-limited

memory_bookmark 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.
