Start a Dagster project
When creating a pipeline, ask the agent for help scaffolding the project and defining assets. The skill supplies guidance on project structure, asset dependencies and the Dagster CLI.
Overview
The Dagster plugin combines guidance for developing data pipelines with tools for accessing a Dagster+ deployment. Its dagster-expert skill guides the agent through project structure, asset patterns, CLI operations and automation. Agents that support automatic skill selection can load it when relevant; you can also invoke dagster-expert directly. The bundled Dagster+ MCP server lets the agent inspect deployment information and take actions such as launching runs. Deployment access requires authentication, and OAuth uses your Dagster+ user permissions; the server is available only in Dagster+ and is in beta.
Use Cases
Choose how a pipeline runs
When a pipeline needs timed or event-driven execution, use the skill's guidance to choose between schedules, sensors and declarative automation.
Investigate a failed deployed run
With the Dagster+ MCP server authenticated, ask the agent to fetch run logs and investigate a failure. The server also exposes actions such as launching runs, so its access extends beyond reading deployment data.

Install
Claude Code
Use a signed-in Claude Code session.
Install dagster only from this marketplace. The dagster-expert plugin is a deprecated migration stub; if both plugins are installed, the stub may be selected instead of the current skill. If you previously installed dagster-expert, uninstall it before installing dagster.
- 01
Add the Dagster marketplace inside your Claude Code session.
/plugin marketplace add dagster-io/skills - 02
Open the dagster plugin's installation panel, choose its installation scope and install it.
/plugin install dagster@dagster - 03
Check the installation summary. If it requests a reload, close the panel to apply it. If activation remains pending, start a new Claude Code session.
- 04
Open the plugin list and switch to Installed. Confirm that dagster is listed and enabled.
/plugin
Connect a Dagster+ account
Authenticate the bundled server if you want to use deployment tools. OAuth grants access using your Dagster+ user permissions; it is not limited to reading data.
Your Dagster+ organization's region
Use the bundled US connection.
- 01
In your terminal, set the EU connection address before launching Claude Code.
export DAGSTER_CLOUD_MCP_URL=https://mcp.agent.eu.dagster.cloud/mcp - 02
Launch a new Claude Code session from that terminal so it inherits the EU setting.
- 01
Inside Claude Code, open the MCP connection manager.
/mcp - 02
Select dagster-plus, then Authenticate. In the browser window, sign in to Dagster+ and allow access to your account.
- 03
Return to the MCP connection manager and check the dagster-plus connection status.
/mcp
Install the dagster plugin directly from its repository folder. This route tracks master rather than release-stable.
If you previously installed the deprecated dagster-expert plugin, uninstall it so its migration stub cannot be selected instead of the current skill.
- 04
Run this command in your terminal to install the dagster plugin.
copilot plugin install dagster-io/skills:plugins/dagster - 05
In your terminal, list installed plugins and confirm that dagster appears, using GitHub's documented plugin-list command.
copilot plugin list - 06
Start a Copilot CLI session. List available skills and look for dagster-expert, using GitHub's documented skill-list command.
/skills list - 07
To inspect the skill's details, use the skill-info command in that session, replacing
NAMEwithdagster-expert./skills info NAME - 08
Open the MCP dashboard and check whether dagster-plus is listed.
/mcp
Deployment access requires Dagster+ authentication. The bundled MCP configuration uses an environment-variable expression with a US default, but Copilot passes remote-server configuration values literally without expanding environment variables. Setting the region variable used by Claude Code will not switch this connection to the EU.
For authenticated deployment access, including EU organizations, consult Dagster's Other Agent Harnesses instructions for regional addresses and authentication options. Dagster does not provide Copilot-specific login or regional setup steps for the bundled server.
Use a signed-in Cursor session. This method adds the Dagster plugin from Cursor's official marketplace.
If you previously installed the dagster-expert plugin, uninstall it before adding dagster; the old plugin contains only migration guidance.
- 04
Open the Customize page in Cursor.
- 05
Search for Dagster, then click Add to add the plugin.
- 06
In Agent chat, type
/and search for dagster-expert to check that the skill is available.
Use Codex CLI for this route. Plugins are not available in the Codex IDE extension.
If you previously installed the deprecated dagster-expert plugin, uninstall it so its migration stub cannot be selected instead of the current skill.
- 04
In your terminal, add the Dagster marketplace from release-stable.
codex plugin marketplace add dagster-io/skills --ref release-stable - 05
In the same terminal, install the dagster plugin from that marketplace.
codex plugin add dagster@dagster - 06
Start a new Codex session so its bundled skills and tools can load.
- 07
Type
$in the prompt to open the skill picker and look for dagster-expert.
Connect a Dagster+ account
Authenticate the server if you want to use deployment tools. OAuth uses your Dagster+ user permissions, including permission to take supported actions.
Your Dagster+ organization's region
Use the plugin's bundled US connection.
- 04
In your terminal, configure dagster-plus with the EU address. Codex needs this explicit setting because it does not support dynamic MCP URLs in plugins.
codex mcp add dagster-plus --url https://mcp.agent.eu.dagster.cloud/mcp
- 04
In your terminal, start authentication for dagster-plus. Complete the browser sign-in and allow access to your Dagster+ account.
codex mcp login dagster-plus - 05
Start a new Codex session, then open the MCP server list. Confirm that dagster-plus is listed as connected.
