icf_explain_qualifier
AI agents call icf_explain_qualifier to retrieve information from ICF MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'explain' operation combined with the sibling tool patterns and server purpose (lookup, search, browsing, explanation) strongly indicates this is a read-only retrieval tool that provides information about ICF qualifiers without modification, deletion, or execution of external commands. No side effects or data mutation expected.
