get_protocol_hierarchy
AI agents call get_protocol_hierarchy to retrieve information from Network MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name indicates a query or retrieval operation that returns protocol hierarchy data without modifying state or executing external code. This aligns with Read category—passive information gathering with no side effects. The empty description prevents higher confidence, but context from related tools suggests diagnostic/informational purpose rather than modification or execution.
From the tool's definition Tool name 'get_protocol_hierarchy' suggests retrieval of protocol structure/information. No destructive, financial, or write operations implied. Sibling tools on this server (analyze_dns_traffic, asn_lookup, cidr_info) are all Read operations.
