Description

This MCP server exposes MongoDB databases to AI assistants for read-only operations such as listing databases and collections, inferring schemas, running queries and aggregations, performing text and geospatial searches, and exporting results. It includes safety validations to prevent write operations, automatic schema inference, visualization hints, and tools for performance insights like query plans and collection statistics. The server integrates with Claude Desktop, Claude Web, and Claude Code, and is configured via environment variables (MONGODB_URI and optional MONGODB_DEFAULT_DATABASE). It is intended for secure data exploration where agents need powerful, read-only access to MongoDB data.
