Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs crow_share_post safely

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

crow_share_post Rate-limited

crow_share_post 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.
