About furey/mongodb-lens
MongoDB Lens is a local Model Context Protocol (MCP) server that provides full-featured access to MongoDB databases using natural language via large language models. It enables users to perform queries, run aggregation pipelines, optimize performance, infer schemas, manage indexes, and more—all through conversational commands. The tool supports a wide range of operations including document CRUD, schema analysis, geospatial queries, text search, bulk operations, and database administration, with built-in safety confirmations for destructive actions. It integrates with MCP-compatible clients like Claude Desktop and Cursor, and requires local installation and configuration.
