MongoDB MCP Server Setup

This skill guides users through configuring the MongoDB MCP server for use with an agentic client.

Overview

The MongoDB MCP server requires authentication. Users have three options:

1. Connection String (Option A): Direct connection to a specific cluster

   • Quick setup for single cluster
   • Requires MDB_MCP_CONNECTION_STRING environment variable

2. Service Account Credentials (Option B): MongoDB Atlas Admin API access

   • Recommended for Atlas users - simplifies authentication and data access
   • Access to Atlas Admin API and dynamic cluster connection via atlas-connect-cluster
   • No manual DB user credential management
   • Requires MDB_MCP_API_CLIENT_ID and MDB_MCP_API_CLIENT_SECRET environment variables

3. Atlas Local (Option C): Local development with Docker
