Conductor OSS
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.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Conductor OSS the way a machine reads it — 38 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Conductor OSS scores 34.6/100 (thin), with a separate agent-readiness read of 17/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Conductor OSS
Each block below is one kind of artifact we hold for Conductor OSS. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 5
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Conductor MCP Server
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 LLM...

Conductor OSS Workflow API
The Workflow API from Conductor OSS — 9 operation(s) for workflow.
Open Collections 6
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

OPEN COLLECTIONFeatures 7

Notable capabilities this provider offers.
Durable Workflow Execution
Workflow state is persisted at every step so executions survive worker restarts, server failover, and long human-in-the-loop waits.
Polyglot Workers
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.
System Tasks and Operators
Built-in HTTP, Kafka, JQ, wait, human approval, sub-workflow, fork, join, switch, do-while, and dynamic-fork operators compose workflows without writing code.
Agentic AI and LLM Orchestration
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.
Event-Driven Triggers
Event handlers consume from Kafka, AMQP, SQS, NATS, and webhook sources to start workflows or complete tasks from external systems.
Horizontal Scalability
Stateless API servers and worker pools scale horizontally, with pluggable persistence (PostgreSQL, MySQL, Cassandra, Redis) and indexing (OpenSearch / Elasticsearch).
Operational Observability
Built-in metrics, structured logs, distributed tracing, and a Swagger UI on every server expose the workflow surface for operators.

Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.
Use Cases 6

This is an independent, third-party profile of Conductor OSS, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
