🚀 The Future of AI is Deterministic

Kubiya SDK is a serverless workflow platform that transforms unpredictable AI agents into reliable, production-grade automation. Every workflow step runs as an independent Docker container, giving you the power to run ANY software while maintaining deterministic execution.

Why We Built This

After watching teams struggle with free-wheeling agent frameworks that promise magic but deliver chaos, we took a different approach. Instead of hoping an AI will figure out the right sequence of actions, we provide the tools to define the right sequence – with AI filling in the intelligent parts. Read more about our architecture →

Core Principles

• 🐳 Serverless Containers: Every step runs in its own Docker container - use ANY language, tool, or software
• 🎯 Deterministic Execution: Same inputs → Same workflow → Same outputs, every time
• 🏗️ Stateless Architecture: Each execution starts fresh with zero state pollution
• 🚀 Infinite Scale: From 1 to 1,000,000 executions without infrastructure changes
• 🤖 MCP Compatible: Works with Claude Desktop, ChatGPT, and any MCP client
• 🏠 Your Infrastructure: Runs entirely on-premise with zero vendor lock-in

✨ Key Features

🎯 Stateless & Serverless Orchestration

🔌 Universal Integration

# Via Kubiya API
client.execute_workflow("deploy-app", params={"version": "2.0"})

# Via MCP Server (works with ANY agent system)
mcp_client.call_tool("execute_workflow", workflow_input="deploy-app")

# Via Agent Server (OpenAI-compatible)
response = openai.chat.completions.create(
    model="kubiya-workflow-agent",
    messages=[{"role": "user", "content": "Deploy version 2.0"}]
)

# Direct in your code
result = workflow.run(params={"env": "production"})

📦 Installation

# Basic installation
pip install kubiya-sdk

# With all features (includes MCP server and agent capabilities)
pip install kubiya-sdk[all]

# For development
pip install kubiya-sdk[dev]

🐳 Docker Installation

# Using Docker Compose (recommended)
docker-compose up -d

# Or run the MCP Agent Server directly
docker run -p 8000:8000 \
  -e KUBIYA_API_KEY=$KUBIYA_API_KEY \
  -e TOGETHER_API_KEY=$TOGETHER_API_KEY \
  kubiya/workflow-sdk:latest \
  mcp agent --provider together --port 8000

🤖 MCP (Model Context Protocol)

Kubiya SDK includes a powerful MCP implementation that enables ANY AI system to create and execute workflows.

Quick Start: MCP Agent Server

The fastest way to get started is with our Agent Server - an OpenAI-compatible API that any AI can use:

# Start the agent server
kubiya mcp agent --provider together --port 8000

# Or with a specific model
kubiya mcp agent --provider anthropic --model claude-3-5-sonnet-20241022 --port 8000

Now ANY OpenAI-compatible client can create workflows:

from openai import OpenAI

client = OpenAI(
    base_url="http://localhost:8000/v1",
    api_key="not-needed"  # Uses env vars for actual API keys
)

response = client.chat.completions.create(
    model="kubiya-workflow-agent",
    messages=[{
        "role": "user", 
        "content": "Create a workflow that backs up all databases to S3"
    }],
    stream=True
)

for chunk in response:
    print(chunk.choices[0].delta.content, end="")

MCP Tools Available

The MCP server provides these tools to AI agents:

1. compile_workflow - Convert DSL to workflow manifest

# AI agents can write simple DSL code
dsl_code = """
from kubiya.dsl import Workflow

wf = Workflow("backup-databases")
wf.description("Backup all databases to S3")
wf.step("backup-postgres", "pg_dump -h $DB_HOST > backup.sql")
wf.step("upload-to-s3", "aws s3 cp backup.sql s3://backups/")
"""

result = compile_workflow(dsl_code=dsl_code)
# Returns: {"success": true, "manifest": {...}}

2. execute_workflow - Run workflows with real-time streaming

# Execute with streaming events
result = execute_workflow(
    workflow_input={"name": "backup-databases", "steps": [...]},
    stream_format="vercel"  # or "raw" for standard events
)
# Streams: step_running, step_complete, workflow_complete events

3. get_workflow_runners - List available execution environments

runners = get_workflow_runners()
# Returns Docker-enabled runners, Kubernetes runners, etc.

4. get_integrations - Discover available integrations

integrations = get_integrations(category="cloud")
# Returns AWS, GCP, Azure integrations with configs

5. get_workflow_secrets - Manage secure credentials

secrets = get_workflow_secrets(pattern="AWS_*")
# Returns available secrets for workflows

Claude Desktop Integration

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "kubiya": {
      "command": "kubiya",
      "args": ["mcp", "server"],
      "env": {
        "KUBIYA_API_KEY": "your-api-key"
      }
    }
  }
}

Now Claude can create and execute workflows directly!

Vercel AI SDK Integration

import { openai } from '@ai-sdk/openai';
import { streamText } from 'ai';

const result = await streamText({
  model: openai('kubiya-workflow-agent', {
    baseURL: 'http://localhost:8000/v1',
  }),
  messages: [
    {
      role: 'user',
      content: 'Create a CI/CD pipeline for my Node.js app',
    },
  ],
});

// Handle streaming with proper event parsing
for await (const chunk of result.textStream) {
  // Vercel format: 0:"text" or 2:{"type":"step_running",...}
  console.log(chunk);
}

Direct MCP Server Usage

For lower-level control, use the MCP server directly:

# Start MCP server (stdio transport)
kubiya mcp server

# The server communicates via stdio, perfect for tool integration

🎯 Quick Start

1. Start the Agent Server

# Set your API keys
export KUBIYA_API_KEY="your-key"
export TOGETHER_API_KEY="your-key"  # Or OPENAI_API_KEY, ANTHROPIC_API_KEY

# Start the server
kubiya mcp agent --provider together --port 8000

2. Create a Workflow with AI

from openai import OpenAI

client = OpenAI(base_url="http://localhost:8000/v1", api_key="not-needed")

# Ask AI to create a workflow
response = client.chat.completions.create(
    model="kubiya-workflow-agent",
    messages=[{
        "role": "user",
        "content": """
        Create a workflow that:
        1. Checks disk space on all servers
        2. Alerts if any disk is over 80% full
        3. Automatically cleans up old logs if needed
        """
    }]
)

print(response.choices[0].message.content)

3. Execute the Workflow

The AI will automatically execute the workflow and stream results in real-time!
