MongoDB MCP Server

A Model Context Protocol server to connect to MongoDB databases and MongoDB Atlas Clusters.

Install

npx -y mongodb-mcp-server@latest --readOnly

Example config (Cursor / Claude Desktop)

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server@latest",
        "--readOnly"
      ],
      "env": {
        "MDB_MCP_API_CLIENT_SECRET": "<your-value>",
        "MDB_MCP_VOYAGE_API_KEY": "<your-value>"
      }
    }
  }
}

VS Code uses "servers" instead of "mcpServers" (why). On Windows, wrap npx with cmd /c (fix).
