What is the Workflows MCP Server?

MCP server for DAG-based workflow execution with YAML definitions and LLM collaboration

What it actually does

Run YAML workflows as MCP tools so agents can automate real tasks with one server.

  • Define tasks once in YAML and run them from any MCP-compatible client
  • Orchestrate multi-step work with dependency-aware execution
  • Support interactive runs (Prompt blocks) with pause/resume
  • Keep secrets server-side via WORKFLOW_SECRET_* with redacted outputs
  • Run synchronous or async jobs with queue visibility and cancellation

Configuration

  • PostgreSQL 13 or later, network-accessible from the server process. - A database user with CREATE DATABASE rights on the admin database (typically postgres) if auto-create is enabled, or a pre-existing database that the user can connect to.
