Dagster enables AI agents to inspect and operate data orchestration pipelines by exploring assets, jobs, schedules, sensors, and runs. Launch and monitor pipeline executions, inspect logs and failures, review asset dependencies, and troubleshoot data workflows across Dagster deployments.
DeepSeek Harness (DSH) is DeepSeek's agent harness. Each MCP server is one plugin entry in your project config.
This guide connects Dagster MCP to DeepSeek Harness through MewCP, so DeepSeek Harness can use Dagster MCP's 36 tools, like list_asset_checks, list_runs and get_run, without your Dagster MCP credentials ever reaching the app.
Dagster MCP signs in through managed OAuth. MewCP stores the token encrypted, refreshes it before it expires and injects it only at call time. Your agent never holds it, so it can never leak it.

Other clients
Dagster MCP works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact Dagster MCP tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
In your DSH project, or the patch file you mount plugins from.
One plugin instance is one MCP server. Add this to your plugin list.
Tools register as mcp__mewcp__<tool_name>. Sign in when the browser window opens.
