Enable observer persona to observe and evaluate other personas capabilities (other-awareness)
AI agents call persona-evaluate-interaction to retrieve information from MCP LLM Generator v2 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is fundamentally a Read operation: it retrieves and examines metadata about persona capabilities without altering system state. Severity is medium (not low) because in a multi-agent system, an LLM could leverage capability introspection to identify and exploit vulnerabilities in other personas or plan coordinated attacks.
From the tool's definition Tool enables observation and evaluation of other personas' capabilities, as indicated by 'observe and evaluate other personas capabilities' and 'other-awareness' classification in the description.
Attacks that exploit this kind of access
Enable observer persona to observe and evaluate other personas capabilities (other-awareness). It is categorised as a Read tool in the MCP LLM Generator v2 MCP Server, which means it retrieves data without modifying state.
Register the MCP LLM Generator v2 MCP server in PolicyLayer and add a rule for persona-evaluate-interaction: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP LLM Generator v2. Nothing to install.
persona-evaluate-interaction is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the persona-evaluate-interaction rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for persona-evaluate-interaction. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
persona-evaluate-interaction is provided by the MCP LLM Generator v2 MCP server (mako10k/mcp-llm-generator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
