List all CouchDB databases
AI agents call listDatabases to retrieve information from CouchDB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates databases without creating, modifying, or deleting any data. It is a pure read operation with minimal blast radius—an AI agent misusing it would at worst enumerate all databases, posing no direct harm to data integrity or system state.
From the tool's definition Tool name 'listDatabases' and description 'List all CouchDB databases' indicate data retrieval with no side effects. Listing is a read-only query operation.
