How do I authenticate?

Add the endpoint in your client, start Connect or Sign in, approve the requested scopes, and return to the client. OAuth discovery finds the authorization server; client registration requirements vary by provider. Follow the provider guidance and client setup below.

Agent prompt for Claude Code or Codex

Add the MongoDB Atlas MCP server to my MCP client configuration and verify that it works.

What it is: Managed MCP access to MongoDB Atlas deployments and data. Uses OAuth in supported clients or Atlas service-account credentials as a bearer token, and must be enabled per organization.
Server URL: https://mcp.mongodb.com/
Transport: Streamable HTTP (remote MCP server, no local install).
Authentication: OAuth 2.1. Registration requirements not verified: The OAuth authorization and app-registration requirements for this exact endpoint have not been verified. A compatible client will request authorization, but follow the publisher documentation and do not guess client credentials or callbacks.
Tools: not yet observed by mcptest; tools/list will show them.
Reference: https://mcptest.io/servers/mongodb-atlas/

Steps:
1. Work out which MCP client I use (Claude Code, Codex, Cursor, VS Code or another) and add the server under the name "mongodb-atlas" in that client's MCP configuration, user scope unless I ask otherwise.
Claude Code: claude mcp add --transport http --scope user 'mongodb-atlas' 'https://mcp.mongodb.com/'
Other clients: use the setup for that client on the reference page.
2. Never write a credential value into a file that could be committed; reference an environment variable or the client's secret store, and ask me for any value you need.
3. Verify: connect to the server and call tools/list. Confirm the tools above are listed, and report any sign-in step I still have to complete.

Claude Code setup

Run in a terminal. This user-scoped entry is available across projects.

claude mcp add --transport http --scope user 'mongodb-atlas' 'https://mcp.mongodb.com/'

After adding the server, open Claude Code, run /mcp, select the server, and follow the browser flow to authenticate.

Codex CLI setup

Run in a terminal; Codex stores the entry in ~/.codex/config.toml.

codex mcp add 'mongodb-atlas' --url 'https://mcp.mongodb.com/'
codex mcp login 'mongodb-atlas'

Cursor setup

Add to .cursor/mcp.json for this project, or ~/.cursor/mcp.json for all projects.

{
  "mcpServers": {
    "mongodb-atlas": {
      "url": "https://mcp.mongodb.com/"
    }
  }
}

VS Code setup

Add to .vscode/mcp.json, or run “MCP: Open User Configuration” for a private user-level entry.

{
  "servers": {
    "mongodb-atlas": {
      "type": "http",
      "url": "https://mcp.mongodb.com/"
    }
  }
}

~/.config/devin/mcp_config.json (%APPDATA%\devin\mcp_config.json on Windows), serverUrl or url
Cascade panel > ... > MCPs > Open MCP config file

Gemini CLI setup

Add the endpoint above in Gemini CLI:

gemini mcp add --transport http <name> <url>
~/.gemini/settings.json (user) or .gemini/settings.json (project), mcpServers

MCP SDK setup

Add the endpoint above in MCP SDK:

Programmatic: new Client(...).connect(new StreamableHTTPClientTransport(url))

Notes for every client

Publisher evidence (reviewed 2026-10-20): https://www.mongodb.com/docs/mcp-server/get-started/
Optional bearer token alternative: Store ATLAS_SERVICE_ACCOUNT_TOKEN in your operating system keychain, secret manager, or protected environment; never commit the value. The Authorization header syntax is Bearer <ATLAS_SERVICE_ACCOUNT_TOKEN>.

Tool inventory

Requires authorization; inventory not observed

The catalog validator lists tools only on servers that answer without credentials. MongoDB Atlas asks for OAuth 2.1 sign-in first, so its tools, resources and prompts were not observed. Connect in the Playground with your own credentials to list them.
