What analyze_rls_coverage does on Supabase MCP Server - Self-Hosted Edition
AI agents call analyze_rls_coverage to retrieve information from Supabase MCP Server - Self-Hosted Edition without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why analyze_rls_coverage is rated Low
RLS coverage analysis is a read-only auditing operation that examines existing security policies without altering data or executing external commands. The context of sibling tools (audit_security, check_health) supports this as a monitoring/inspection function. Empty description prevents higher confidence, but the semantic meaning of 'analyze' and 'coverage' strongly suggests introspection over mutation.
From the tool's definition Tool name 'analyze_rls_coverage' suggests analysis of Row-Level Security policy coverage; the suffix 'analyze' and 'coverage' imply inspection/audit rather than modification. Description is empty, reducing confidence.
