Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_item safely

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

update_item Rate-limited

update_item 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.
