Queries and aggregations over MCP

Official MongoDB MCP server — connect Claude or Cursor to a local instance or Atlas cluster to explore collections, run queries and aggregations, and inspect schema. Pass the connection string via the MDB_MCP_CONNECTION_STRING env var and start in --readOnly mode so the AI can analyse but not mutate data. Atlas needs your IP allow-listed.

Install MongoDB MCP Server

Paste into claude_desktop_config.json

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server@latest",
        "--readOnly"
      ]
    }
  }
}

Run in your terminal

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

Paste into .cursor/mcp.json

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server@latest",
        "--readOnly"
      ]
    }
  }
}

After adding the server, fully restart your MCP client. Replace <placeholders> (tokens, paths) with your own values.

Known limitations

Keep --readOnly on unless you explicitly need writes, and never run write-enabled against production. The connection string grants database access — pass it via env, never inline in shared config.
