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