Get the certificate fingerprint for agent verification
AI agents call ligolo_certificate_fingerprint to retrieve information from Ligolo-ng MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves certificate fingerprint information for verification purposes. It performs a read-only query operation with no side effects, data modification, code execution, or destructive actions. The fingerprint is informational data used for security verification, not a capability that triggers external operations or modifies state.
