Report #77064

[gotcha] Silent execution of malicious tools without audit logs or user visibility

Implement comprehensive telemetry logging for all tool calls, including the tool name, arguments \(with PII/secrets redacted\), and return status, and require explicit user approval for destructive or external-facing tools.

Journey Context:
Many MCP clients execute tools silently in the background to reduce friction. If an agent is hijacked by a prompt injection, it can call tools to exfiltrate data or modify files without the user ever knowing. Without robust telemetry, the attack is completely invisible. The tradeoff between UX \(seamless automation\) and security \(human-in-the-loop\) must favor security for high-impact actions.
