MongoDB MCP Server

MCPOpen Source35.5

by 1RB • Data & Databases

An MCP server that lets LLM-based agents query, inspect, and manage MongoDB databases via the Model Context Protocol.

Example Use Cases

1
List and inspect collection schemas to understand database structure before issuing queries.
2
Query, filter, and project documents from MongoDB using natural language prompts and return structured results.
3
Perform data administration tasks like creating/dropping indexes and inserting/updating/deleting documents programmatically.

Description

This server exposes MongoDB operations (list collections, query documents, insert/update/delete, and index management) as MCP tools so LLM clients like Claude Desktop and Cursor.ai can interact with databases using natural language. It includes schema inspection, Zod-based validation, and comprehensive error handling to reduce injection and misuse risks. The project supports local and containerized deployment and provides examples and a test sandbox to get started quickly. Security guidance and recommended least-privilege practices are documented for safe usage.
