WHAT IT DOES

What analyze_hnsw_recall does on Mcpg

AI agents call analyze_hnsw_recall to retrieve information from Mcpg without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why analyze_hnsw_recall is rated Low

The tool appears to query or compute metrics about HNSW index performance without altering state. Despite the empty description lowering confidence slightly, the naming pattern strongly suggests a read-only diagnostic operation consistent with other 'analyze_' tools on the same PostgreSQL MCP server. No evidence of data modification, deletion, code execution, or financial impact.

From the tool's definition Tool name 'analyze_hnsw_recall' indicates analysis/inspection of HNSW (Hierarchical Navigable Small World) index recall metrics.
