Dagster+ MCP server

Dagster+ feature

This feature is only available in Dagster+.

Beta feature

This feature is considered in a beta stage. It is still being tested and may change. For more information, see the API lifecycle stages documentation.

The Dagster+ MCP server allows you to access information and take actions in your Dagster+ deployment within an AI session.

The server URL depends on the region your organization is in:

Region	URL
US	https://mcp.agent.dagster.cloud/mcp
EU	https://mcp.agent.eu.dagster.cloud/mcp

The examples below use the US URL. If your organization is in the EU region, substitute the EU URL.

Connecting to the MCP server

You can connect to the Dagster+ MCP server using OAuth or by manually specifying a few headers. Using OAuth will use your user permissions when determining the MCP server permissions. If you would like to create a different set of permissions for the MCP server, we recommend creating a service user and providing authentication headers when adding the MCP server. See the Other Agent Harnesses section below for instructions for using headers for authentication.

Claude Code

1. Install and sign in to Claude Code using the setup guide.

2. Within your terminal, run the following command:

   claude mcp add --transport http dagster-plus https://mcp.agent.dagster.cloud/mcp

   EU users should specify the URL https://mcp.agent.eu.dagster.cloud/mcp

3. Start a claude session and type /mcp. Select the dagster-plus MCP server and select Authenticate. This will open a browser window where you can log into Dagster+ and allow the MCP server access to your account.

Codex

1. Install Codex from the official setup guide and sign in.

2. Within your terminal, run the following command:

   codex mcp add dagster-plus --url https://mcp.agent.dagster.cloud/mcp

   EU users should specify the URL https://mcp.agent.eu.dagster.cloud/mcp

3. An authentication flow should immediately open and prompt you to allow the MCP server to access your Dagster+ account.

4. Start a codex session and type /mcp. You should see dagster-plus listed as connected.

   

Other Agent Harnesses

If your agent harness supports OAuth, add the Dagster+ MCP server at https://mcp.agent.dagster.cloud/mcp (or https://mcp.agent.eu.dagster.cloud/mcp for EU users). Start the OAuth flow for the MCP server according to your provider's instructions.

You can also connect to the Dagster+ MCP server by specifying a URL and a few headers. This bypasses authentication through OAuth.

• URL: https://mcp.agent.dagster.cloud/mcp (EU: https://mcp.agent.eu.dagster.cloud/mcp)

• Headers:

  • Authorization: Bearer [your user token]
  • Dagster-Cloud-Organization: [your dagster organization]

For information on accessing your user token, see Managing user tokens in Dagster+.

Example: Adding the Dagster+ MCP server to Claude Code with custom headers

Within your terminal, run the following command:

claude mcp add --transport http dagster-plus https://mcp.agent.dagster.cloud/mcp --header "Dagster-Cloud-Organization: [organization]" --header "Authorization: Bearer [token]"
