# 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 - **Best for local testing** - zero configuration required - Runs Atlas locally in Docker, requires Docker installed - No credentials or cloud cluster access This is an interactive step-by-step guide. The agent detects the user's environment and provides tailored instructions, but **never asks for or handles credentials** — users add those directly to their shell profile or agentic client config in Step 5. Make this clear to the user whenever credentials come up in Steps 3a and 3b. ## Step 0: Detect Client Before anything else, determine which agentic client the user is running. This controls how credentials are configured in Step 1 and St...
