AI agents call get_all_table_references to retrieve information from Sql Analyzer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool extracts and returns table references from SQL without executing queries, modifying data, or triggering external operations. It is a read-only analysis function. Confidence is not higher (0.85 vs 1.0) because the description is empty, leaving minor room for ambiguity, but context from sibling tools and server purpose strongly indicate a safe introspection operation.

{
"version": "1",
"default": "deny",
"tools": {
"get_all_table_references": {}
