  Conductor OSS is the Netflix-founded, Orkes-stewarded open source workflow
  and agentic AI orchestration platform. It provides a durable, event-driven
  workflow engine for coordinating microservices, long-running tasks, human
  approvals, and LLM-powered agents across any language or cloud, with first
  class support for HTTP, gRPC, Kafka, AMQP, SQS, and MCP-based tool calling.

  name: Conductor OSS REST API
  description: >-
    The Conductor OSS REST API is the canonical control plane for the workflow
    engine — registering and versioning workflow and task definitions,
    starting and querying workflow executions, polling and updating tasks
    from workers, and wiring external event sources into workflows. It is
    served by the Conductor Server (Java / Spring Boot) and is the same
    surface used by every official Conductor SDK and the Orkes-hosted
    Conductor Cloud.

  name: Conductor MCP Server
  description: >-
    Conductor MCP is an official Model Context Protocol server for Orkes
    Conductor that exposes workflow execution, task management, and metadata
    operations as MCP tools so that LLMs and AI agents can orchestrate
    Conductor workflows directly.

  data:
  - name: Durable Workflow Execution
    description: >-
      Workflow state is persisted at every step so executions survive worker
      restarts, server failover, and long human-in-the-loop waits.
  - name: Polyglot Workers
    description: >-
      Tasks are executed by language-agnostic workers that poll the server,
      with official SDKs in Java, Python, Go, JavaScript / TypeScript, C#,
      Clojure, Ruby, and Rust.
  - name: System Tasks and Operators
    description: >-
      Built-in HTTP, Kafka, JQ, wait, human approval, sub-workflow, fork,
      join, switch, do-while, and dynamic-fork operators compose workflows
      without writing code.
  - name: Agentic AI and LLM Orchestration
    description: >-
      Native LLM tasks for 14+ providers, vector database integrations for
      RAG, MCP tool calling, and human-in-the-loop checkpoints make
      Conductor a runtime for agentic AI applications.
  - name: Event-Driven Triggers
    description: >-
      Event handlers consume from Kafka, AMQP, SQS, NATS, and webhook
      sources to start workflows or complete tasks from external systems.
  - name: Horizontal Scalability
    description: >-
      Stateless API servers and worker pools scale horizontally, with
      pluggable persistence (PostgreSQL, MySQL, Cassandra, Redis) and
      indexing (OpenSearch / Elasticsearch).
  - name: Operational Observability
    description: >-
      Built-in metrics, structured logs, distributed tracing, and a Swagger
      UI on every server expose the workflow surface for operators.
