Install MongoDB

Runs on your machine. Your client starts it with this command:

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

Needs Node.js on your computer. The setup steps below show where the command goes in each client.

  • MDB_MCP_ALLOW_REQUEST_OVERRIDES optional When set to true, allows configuration values to be overridden via request headers and query parameters.
  • MDB_MCP_API_CLIENT_ID secret optional Atlas API client ID for authentication. Required for running Atlas tools.
  • MDB_MCP_API_CLIENT_SECRET secret optional Atlas API client secret for authentication. Required for running Atlas tools.
  • MDB_MCP_ASSISTANT_BASE_URL optional Base URL for the MongoDB Assistant API.
  • MDB_MCP_ATLAS_TEMPORARY_DATABASE_USER_LIFETIME_MS optional Time in milliseconds that temporary database users created when connecting to MongoDB Atlas clusters will remain active before being…
  • MDB_MCP_CONFIRMATION_REQUIRED_TOOLS optional Comma separated values of tool names that require user confirmation before execution. Requires the client to support elicitation.

About

Conecta un asistente de IA a bases de datos MongoDB y a MongoDB Atlas. Puede trabajar con datos en despliegues autogestionados o de Atlas mediante una cadena de conexión, y gestionar recursos de Atlas a través de la API de Atlas. El README agrupa sus herramientas en las categorías Atlas, base de datos y MongoDB Assistant.

Se ejecuta localmente por stdio como el paquete npm mongodb-mcp-server (también publicado como imagen de Docker) y requiere Node.js 22.13 o posterior. La autenticación usa una cadena de conexión de MongoDB o credenciales de API de una cuenta de servicio de Atlas, pasadas como variables de entorno. El flag --readOnly lo limita a operaciones de lectura. MongoDB también ofrece un servidor MCP de Atlas alojado con OAuth mediante sus plugins para agentes.

What you can do

  • Conectarse a despliegues de MongoDB con una cadena de conexión
  • Trabajar con datos de MongoDB mediante herramientas de base de datos
  • Gestionar recursos de MongoDB Atlas con credenciales de la API de Atlas
  • Ejecutar en modo de solo lectura con el flag --readOnly
  • Desactivar herramientas o exigir confirmación en las seleccionadas
  • Desactivar los operadores JavaScript del lado del servidor en las consultas

Tools

MongoDB lists its tools only to clients with a key, so we can’t show them here.

Example prompts

  • Lista las colecciones de mi base de datos MongoDB

  • Encuentra los 10 pedidos más recientes en la colección orders

  • Muestra mis clústeres de Atlas

  • Describe los índices de la colección users

Set up

Every client starts MongoDB on your machine with the same command. Pick yours; the page remembers your choice.

Claude Code

  1. Run this in a terminal, in your project folder:
claude mcp add --transport stdio mongodb --env "MDB_MCP_API_CLIENT_ID=<YOUR_MDB_MCP_API_CLIENT_ID>" --env "MDB_MCP_API_CLIENT_SECRET=<YOUR_MDB_MCP_API_CLIENT_SECRET>" --env "MDB_MCP_CONNECTION_STRING=<YOUR_MDB_MCP_CONNECTION_STRING>" -- npx -y mongodb-mcp-server@latest --readOnly
  1. Start Claude Code and type /mcp. mongodb should show as connected.

Add --scope user to make it available in every project. Replace the placeholders with your own values.

Claude Desktop

  1. Open Settings → Developer → Edit Config. It opens claude_desktop_config.json. Add:
claude_desktop_config.json
{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server@latest",
        "--readOnly"
      ],
      "env": {
        "MDB_MCP_API_CLIENT_ID": "<YOUR_MDB_MCP_API_CLIENT_ID>",
        "MDB_MCP_API_CLIENT_SECRET": "<YOUR_MDB_MCP_API_CLIENT_SECRET>",
        "MDB_MCP_CONNECTION_STRING": "<YOUR_MDB_MCP_CONNECTION_STRING>"
      }
    }
  }
}
  1. Save the file and restart Claude Desktop. Replace the placeholders with your own values.

Needs Node.js on your computer. The file lives in ~/Library/Application Support/Claude/ on macOS and %APPDATA%\Claude\ on Windows.

Cursor

Add to Cursor (opens in a new tab)

Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):

mcp.json
{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server@latest",
        "--readOnly"
      ],
      "env": {
        "MDB_MCP_API_CLIENT_ID": "<YOUR_MDB_MCP_API_CLIENT_ID>",
        "MDB_MCP_API_CLIENT_SECRET": "<YOUR_MDB_MCP_API_CLIENT_SECRET>",
        "MDB_MCP_CONNECTION_STRING": "<YOUR_MDB_MCP_CONNECTION_STRING>"
      }
    }
  }
}

Needs Node.js on your computer. Replace the placeholders with your own values.

VS Code

Add it to .vscode/mcp.json. VS Code asks for the secret the first time and stores it securely:

.vscode/mcp.json
{
  "servers": {
    "mongodb": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server@latest",
        "--readOnly"
      ],
      "env": {
        "MDB_MCP_API_CLIENT_ID": "${input:mdb-mcp-api-client-id}",
        "MDB_MCP_API_CLIENT_SECRET": "${input:mdb-mcp-api-client-secret}",
        "MDB_MCP_CONNECTION_STRING": "${input:mdb-mcp-connection-string}"
      }
    }
  },
  "inputs": [
    {
      "type": "promptString",
      "id": "mdb-mcp-api-client-id",
      "description": "MDB_MCP_API_CLIENT_ID",
      "password": true
    },
    {
      "type": "promptString",
      "id": "mdb-mcp-api-client-secret",
      "description": "MDB_MCP_API_CLIENT_SECRET",
      "password": true
    },
    {
      "type": "promptString",
      "id": "mdb-mcp-connection-string",
      "description": "MDB_MCP_CONNECTION_STRING",
      "password": true
    }
  ]
}

Needs Node.js on your computer.

Devin Desktop

  1. Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):
mcp_config.json
{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server@latest",
        "--readOnly"
      ],
      "env": {
        "MDB_MCP_API_CLIENT_ID": "<YOUR_MDB_MCP_API_CLIENT_ID>",
        "MDB_MCP_API_CLIENT_SECRET": "<YOUR_MDB_MCP_API_CLIENT_SECRET>",
        "MDB_MCP_CONNECTION_STRING": "<YOUR_MDB_MCP_CONNECTION_STRING>"
      }
    }
  }
}
  1. Refresh the MCP server list in Cascade. Replace the placeholders with your own values.

Devin Desktop is the new name for Windsurf.

Codex

codex mcp add mongodb --env "MDB_MCP_API_CLIENT_ID=<YOUR_MDB_MCP_API_CLIENT_ID>" --env "MDB_MCP_API_CLIENT_SECRET=<YOUR_MDB_MCP_API_CLIENT_SECRET>" --env "MDB_MCP_CONNECTION_STRING=<YOUR_MDB_MCP_CONNECTION_STRING>" -- npx -y mongodb-mcp-server@latest --readOnly

Or edit ~/.codex/config.toml directly:

config.toml
[mcp_servers.mongodb]
command = "npx"
args = ["-y", "mongodb-mcp-server@latest", "--readOnly"]
env = { MDB_MCP_API_CLIENT_ID = "<YOUR_MDB_MCP_API_CLIENT_ID>", MDB_MCP_API_CLIENT_SECRET = "<YOUR_MDB_MCP_API_CLIENT_SECRET>", MDB_MCP_CONNECTION_STRING = "<YOUR_MDB_MCP_CONNECTION_STRING>" }

Needs Node.js on your computer. Replace the placeholders with your own values.

Gemini CLI

gemini mcp add -e "MDB_MCP_API_CLIENT_ID=<YOUR_MDB_MCP_API_CLIENT_ID>" -e "MDB_MCP_API_CLIENT_SECRET=<YOUR_MDB_MCP_API_CLIENT_SECRET>" -e "MDB_MCP_CONNECTION_STRING=<YOUR_MDB_MCP_CONNECTION_STRING>" mongodb npx -- -y mongodb-mcp-server@latest --readOnly

This adds it to the current project. Add -s user to use it everywhere.

Any client

Most clients that start local servers accept this shape:

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server@latest",
        "--readOnly"
      ],
      "env": {
        "MDB_MCP_API_CLIENT_ID": "<YOUR_MDB_MCP_API_CLIENT_ID>",
        "MDB_MCP_API_CLIENT_SECRET": "<YOUR_MDB_MCP_API_CLIENT_SECRET>",
        "MDB_MCP_CONNECTION_STRING": "<YOUR_MDB_MCP_CONNECTION_STRING>"
      }
    }
  }
}

Zed puts servers under context_servers in its settings, with the same command, args and env fields.

Needs Node.js on your computer. Replace the placeholders with your own values.

FAQ

Can I paste mcp.tc/i/mongodb into my MCP client?

No. MongoDB runs on your own computer, started by your client, so it has no web address to connect to. The quick link is the page to share; the install command is npx -y mongodb-mcp-server@latest --readOnly.

Does MongoDB need an API key?

Yes. It reads MDB_MCP_API_CLIENT_ID, MDB_MCP_API_CLIENT_SECRET and MDB_MCP_CONNECTION_STRING from its environment, and MDB_MCP_API_CLIENT_ID, MDB_MCP_API_CLIENT_SECRET and MDB_MCP_CONNECTION_STRING are secrets. Put the values in your client’s config on your own machine, never in a shared file.

Is MongoDB a remote or a local server?

Local. Your client starts it as a process on your computer with npx -y mongodb-mcp-server@latest --readOnly, which needs Node.js.

What can MongoDB do?

You can conectarse a despliegues de MongoDB con una cadena de conexión, trabajar con datos de MongoDB mediante herramientas de base de datos and gestionar recursos de MongoDB Atlas con credenciales de la API de Atlas.

Which clients can use it?

Any client that starts local servers: Claude Code, Claude Desktop, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others. claude.ai and ChatGPT only connect to remote servers.
