WHAT IT DOES

What list_enabled_databases does on Multi-DB MCP Server

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

RISK

Why list_enabled_databases is rated Low

This tool retrieves and queries configuration metadata without side effects. It does not modify, execute, or delete anything. It falls squarely into the Read category—safe informational access. Severity is low because exposure of which database systems are enabled poses minimal security risk on its own, though it could inform reconnaissance. Confidence is high because the name and description are unambiguous.

From the tool's definition Tool name 'list_enabled_databases' and description 'List enabled database targets' indicates a query/retrieval operation with no data modification. Returns only configuration metadata about which database systems are enabled.
