List all Mango indexes in a database (CouchDB 3.x+)
AI agents call listMangoIndexes 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 existing Mango indexes from a CouchDB database. It performs a read-only operation with no side effects—no data is created, modified, deleted, or executed. The blast radius of misuse is minimal, as listing indexes cannot harm data or trigger unintended operations.
