xano_list_databases
AI agents call xano_list_databases to retrieve information from Xano MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list' action retrieves and enumerates databases without modifying, deleting, or executing operations. Even if an AI agent misuses this tool, it only exposes database names/metadata with no destructive, financial, or code execution effects. Severity is low due to limited blast radius—it reveals structure but not data contents.
From the tool's definition Tool name 'xano_list_databases' indicates a list operation, which is a read-only retrieval of database metadata. The description is empty, but the naming convention aligns with standard Read operations (list/get/fetch patterns).
