MongoDB MCP Connector

Example Use Cases

• 1

  Read-only access to a MongoDB database to fetch collection documents and database state via ReadResource requests.

• 3

  Run multi-collection aggregation queries (e.g., $lookup joins) to enrich documents from related collections.

Description

This repository provides an MCP configuration and examples for running a MongoDB-backed MCP server tool. It includes sample configuration (command, args, env), sample ReadResource and CallTool request schemas, and examples for multi-collection aggregation queries using $lookup. The setup is geared toward enabling agents to read resources (read-only access) and execute operations (calls) against a MongoDB database.
