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