Attacks that exploit this kind of access
The rule that runs list_providers safely
PolicyLayer is an MCP gateway: it sits between your AI agents and A2wave, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_providers, this is the rule to start with:
list_providers is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect A2wave, apply this rule, and every list_providers call is checked against it from then on.
