description: >-
  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.

      - 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: >-
