Conductor AI Workflow Examples

This folder contains ready-to-use workflow examples demonstrating the AI capabilities of Conductor.

Prerequisites

1. Start Conductor Server

Ensure Conductor is running with AI integrations enabled:

# From the conductor root directory
./gradlew bootRun

2. Configure AI Providers

Set environment variables before starting the server:

# OpenAI (required for most examples)
export OPENAI_API_KEY=sk-your-openai-api-key

# Anthropic (optional, for RAG examples)
export ANTHROPIC_API_KEY=sk-ant-your-anthropic-key

# Google Gemini (optional, for Gemini/Veo examples)
# Option 1: API key (simplest)
export GEMINI_API_KEY=your-gemini-api-key
# Option 2: Vertex AI — set project and location in application.properties

For vector database examples, add to application.properties:

# PostgreSQL Vector DB (for RAG/embedding examples)
conductor.vectordb.instances[0].name=postgres-prod
conductor.vectordb.instances[0].type=postgres
conductor.vectordb.instances[0].postgres.datasourceURL=jdbc:postgresql://localhost:5432/vectors
conductor.vectordb.instances[0].postgres.user=conductor
conductor.vectordb.instances[0].postgres.password=secret
conductor.vectordb.instances[0].postgres.dimensions=1536

3. MCP Test Server (for MCP examples)

Install and start the MCP test server:

# Install mcp-testkit — a test MCP server with 65 deterministic tools
pip install mcp-testkit

# Start the server in HTTP mode
mcp-testkit --transport http

The server will be available at http://localhost:3001/mcp.

A2A (Agent2Agent) examples

Conductor as an A2A client (calling remote agents) and server (exposing a workflow as an agent). The client tasks (AGENT, GET_AGENT_CARD, CANCEL_AGENT) need a reachable A2A agent — see ai/src/test/resources/a2a/ for a runnable test agent. The server examples are exposed by registering them with metadata.a2a.enabled=true and conductor.a2a.server.enabled=true.

Quick Start

Step 1: Register a Workflow

# Register the chat completion workflow
curl -X POST 'http://localhost:8080/api/metadata/workflow' \
  -H 'Content-Type: application/json' \
  -d @01-chat-completion.json

Step 2: Execute the Workflow

# Run the workflow (no input needed for hardcoded examples)
curl -X POST 'http://localhost:8080/api/workflow/chat_workflow' \
  -H 'Content-Type: application/json' \
  -d '{}'

Step 3: Check the Result

# Get workflow execution status (replace {workflowId} with the returned ID)
curl -X GET 'http://localhost:8080/api/workflow/{workflowId}'

30. RAG on SQLite (sqlite-vec, zero infrastructure)

Runs the full index → search → answer RAG loop against the embedded SQLite + sqlite-vec vector store — no PostgreSQL, MongoDB or Pinecone required. When the server runs with conductor.db.type=sqlite and conductor.integrations.ai.enabled=true, Conductor bundles the native vec0 extension and auto-registers a vector DB instance named default, which this workflow targets. Embeddings are requested at 256 dimensions to match that default instance.

Troubleshooting

"VectorDB not found: postgres-prod"

Ensure you have configured the PostgreSQL vector database in your application.properties:

conductor.vectordb.instances[0].name=postgres-prod
conductor.vectordb.instances[0].type=postgres
conductor.vectordb.instances[0].postgres.datasourceURL=jdbc:postgresql://localhost:5432/vectors
conductor.vectordb.instances[0].postgres.user=conductor
conductor.vectordb.instances[0].postgres.password=secret
conductor.vectordb.instances[0].postgres.dimensions=1536

"No configuration found for: openai"

Ensure you have set the OpenAI API key environment variable:

export OPENAI_API_KEY=sk-your-openai-api-key

MCP Server Connection Refused

1. Verify the MCP server is running:

   curl http://localhost:3001/mcp
   

2. Check the server logs for errors

3. Ensure you're using the correct port in the workflow (default: 3001)

PostgreSQL Vector Extension Not Found

Ensure the pgvector extension is installed in your PostgreSQL database:

CREATE EXTENSION IF NOT EXISTS vector;
