MongoDB Mongoose MCP is an MCP server that lets Claude interact with MongoDB databases using either the native MongoDB driver for direct operations or Mongoose schemas for validation and hooks when available. It supports core data operations: querying (including filtering and projection), aggregation, inserting, updating, and soft deleting documents, with a clear separation between schema-based (Mongoose) and schemaless workflows. When a SCHEMA_PATH is provided, the MCP loads Mongoose models from that directory so operations benefit from defined schemas, validation, and lifecycle hooks; if no schemas are supplied, operations run directly against collections. The server exposes MCP commands such as find, listCollections, insertOne, updateOne, deleteOne (soft delete), count, and aggregate, along with index tools like createIndex, dropIndex, and indexes. Prerequisites include Node.js v18+ and MongoDB. To use with Claude Desktop, configure claude_desktop_config.json under mcpServers.mongodb-mongoose, setting MONGODB_URI and SCHEMA_PATH accordingly. A sample schema in the repo shows common fields such as isDeleted and deletedAt for soft delete, and the SCHEMA_PATH should reflect the folder containing your models (filenames matching collection names).
