Attacks that exploit this kind of access
The rule that runs linear_addIssueLabel safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Linear, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For linear_addIssueLabel, this is the rule to start with:
linear_addIssueLabel 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Linear, apply this rule, and every linear_addIssueLabel call is checked against it from then on.
