Operate Harness pipelines, projects, and delivery resources from MCP-enabled agents
Use the Harness MCP Server when an agent needs governed access to Harness pipelines, services, environments, feature flags, cost data, and related platform resources from an MCP workflow instead of sending a human through the Harness UI.
Operate DingTalk messages, docs, approvals, and workspace tasks from agents with DingTalk Workspace CLI
Handle DingTalk workspace actions from one CLI surface instead of building a fresh integration for each message, approval, or document task.
Operate Airflow and warehouse workflows through agent-safe data engineering skills with Astronomer Agents
Give agents structured Airflow, lineage, dbt, and warehouse workflows through installable skills and an Airflow MCP surface instead of loose shell access.
