SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps users who have a MongoDB MCP server installed but lack the required environment variables or credentials to connect agents and tools to MongoDB or Atlas, eliminating guesswork and preventing unsafe credential handling.

Core Features & Use Cases

  • Multiple authentication paths: Guides through Connection String (single cluster), Atlas Service Account (recommended for Atlas users), or Atlas Local (Docker) setups.
  • Safe credential handling guidance: Instructs users to store secrets in a dedicated ~/.mcp-env file, restrict permissions, and source the file from their shell profile without ever asking for credentials.
  • Operational checks and verification: Commands and checks to detect existing MDB_MCP variables, verify read-only mode, and confirm the agentic client picks up the environment.
  • Use Case: Onboarding an agentic client to production Atlas with service account credentials and IP-restricted API access, or enabling a local developer to run Atlas Local via Docker for testing.

Quick Start

Configure your shell to source a ~/.mcp-env file containing MDB_MCP_CONNECTION_STRING or MDB_MCP_API_CLIENT_ID and MDB_MCP_API_CLIENT_SECRET and then verify the variables are set.

FAQPage Schema
How do I configure environment variables for the MongoDB MCP server?▼

Configure MongoDB MCP server environment variables by adding MDB_MCP_CONNECTION_STRING or Atlas API credentials to a dedicated file, then source it from your shell profile. This guides authentication and connection setup for agentic clients.

What is the best way to set up MongoDB Atlas service accounts for an MCP server?▼

Setting up MongoDB Atlas service accounts for an MCP server involves defining MDB_MCP_API_CLIENT_ID and MDB_MCP_API_CLIENT_SECRET. Storing these in a restricted ~/.mcp-env file is recommended for safe credential handling.

Can I use a local MongoDB Atlas instance via Docker for MCP server testing?▼

Yes, you can use a local Atlas instance via Docker for MCP server testing. This provides a local development environment to verify agentic client connections before moving to production access.

How do I enable read-only mode for the MongoDB MCP server?▼

Enable read-only mode for the MongoDB MCP server by setting the MDB_MCP_READ_ONLY environment variable. You can then verify this setting using operational checks to confirm the configuration.

How do I verify that my agentic client picks up MongoDB MCP server environment variables?▼

Verify agentic client pickup of MongoDB MCP server variables by running operational checks to detect existing MDB_MCP variables. Ensure your shell profile correctly sources the ~/.mcp-env file before confirming.
