MongoDB Lens

MongoDB Lens v9.1.4 is a full-featured Model Context Protocol (MCP) server that provides natural language access to MongoDB databases via LLMs like Claude. It enables querying, aggregation, schema analysis, performance optimization, and data manipulation through MCP tools, resources, and prompts. The package is actively maintained with regular releases on npm and Docker. Key differentiators include a comprehensive set of tools (over 30), built-in data protection with confirmation for destructive operations, memory caching, and support for multiple connection aliases. It requires Node.js >=18 and the MongoDB driver.
