AI Agents in Activepieces

Activepieces is AI-first, providing native AI capabilities that let you build intelligent workflows capable of reasoning, decision-making, and multi-step task execution. With support for multiple AI providers and a powerful agent framework, you can create automations that go far beyond simple if-then logic.

What are AI Agents?

AI agents in Activepieces are intelligent automation components that can:

Reason through problems: Analyze situations and determine the best course of action
Use tools: Call other Activepieces actions, APIs, and MCP servers to accomplish tasks
Iterate until complete: Keep working on a task until it’s successfully done
Extract structured data: Parse unstructured text into organized information
Make decisions: Choose different workflow paths based on AI analysis
Generate content: Create text, images, and other media

AI agents can handle complex, multi-step tasks that would traditionally require extensive programming and conditional logic.

Agent Actions

Run Agent

The most powerful AI action - agents that can use tools and reason through complex tasks:

{
  actionName: 'run_agent',
  input: {
    prompt: 'Find all customers who haven\'t been contacted in 30 days and send them a personalized re-engagement email',
    aiProviderModel: {
      provider: AIProviderName.ANTHROPIC,
      model: 'claude-3-5-sonnet-20241022',
      apiKey: '{{connections.anthropic}}'
    },
    agentTools: [
      {
        type: 'PIECE',
        toolName: 'search_database',
        pieceMetadata: {
          pieceName: '@activepieces/piece-postgres',
          actionName: 'execute_query'
        }
      },
      {
        type: 'PIECE',
        toolName: 'send_email',
        pieceMetadata: {
          pieceName: '@activepieces/piece-sendgrid',
          actionName: 'send_email'
        }
      },
      {
        type: 'FLOW',
        toolName: 'generate_email_content',
        externalFlowId: 'email-generator-flow'
      },
      {
        type: 'MCP',
        toolName: 'analyze_customer',
        serverUrl: 'https://mcp.example.com',
        protocol: 'sse'
      }
    ],
    structuredOutput: [
      {
        displayName: 'Customers Contacted',
        type: 'number'
      },
      {
        displayName: 'Emails Sent',
        type: 'number'
      },
      {
        displayName: 'Errors',

Example 1: Intelligent Customer Support

// Flow: "AI Customer Support Agent"
{
  trigger: {
    type: 'WEBHOOK',
    settings: { /* webhook config */ }
  },
  actions: [
    // Step 1: Classify the support request
    {
      name: 'classify_request',
      actionName: 'classify_text',
      input: {
        text: '{{trigger.body.message}}',
        categories: ['bug_report', 'feature_request', 'billing', 'technical_support', 'general_inquiry']
      }
    },
    // Step 2: Extract structured information
    {
      name: 'extract_info',
      actionName: 'extract_structured_data',
      input: {
        text: '{{trigger.body.message}}',
        schema: {
          customerName: 'string',
          issueDescription: 'string',
          affectedFeature: 'string',
          urgency: 'string'
        }
      }
    },
    // Step 3: Run agent to handle the request
    {
      name: 'handle_request',
      actionName: 'run_agent',
      input: {
        prompt: `Handle this {{steps.classify_request.output.category}} request:
                Customer: {{steps.extract_info.output.customerName}}
                Issue: {{steps.extract_info.output.issueDescription}}
                
                Search our knowledge base, create a ticket if needed, and draft a response.`,
        agentTools: [
          // Tool to search knowledge base
          {
            type: 'FLOW',
            toolName: 'search_knowledge_base',
            externalFlowId: 'kb-search-flow'
          },
          // Tool to create ticket
          {
            type: 'PIECE',
            toolName: 'create_ticket',
            pieceMetadata: {
              pieceName: '@activepieces/piece-zendesk',
              actionName: 'create_ticket'
            }
          }
        ]
      }
    },
    // Step 4: Send response
    {
      name: 'send_response',
      actionName: 'send_email',
      input: {
        to: '{{trigger.body.email}}',
        subject: 'Re: Your Support Request',
        body: '{{steps.handle_request.output.response}}'
      }
    }
  ]
}

Example 2: Content Generation Pipeline

// Flow: "AI Content Generator"
{
  trigger: {
    type: 'SCHEDULE',
    settings: {
      cronExpression: '0 9 * * 1' // Every Monday at 9 AM
    }
  },
  actions: [
    // Step 1: Agent researches topic
    {
      name: 'research_topic',
      actionName: 'run_agent',
      input: {
        prompt: 'Research the latest trends in {{workflow.topic}} and identify 3 interesting angles for blog posts',
        agentTools: [
          {
            type: 'PIECE',
            toolName: 'web_search',
            pieceMetadata: {
              pieceName: '@activepieces/piece-google',
              actionName: 'search'
            }
          }
        ],
        structuredOutput: [
          {
            displayName: 'Topics',
            type: 'array'
          }
        ]
      }
    },
    // Step 2: Generate content for each topic
    {
      name: 'generate_posts',
      type: 'LOOP',
      settings: {
        items: '{{steps.research_topic.output.topics}}',
        loopActions: [
          {
            actionName: 'ask_ai',
            input: {
              prompt: 'Write a 500-word blog post about: {{loop.item}}',
              temperature: 0.8
            }
          },
          {
            actionName: 'generate_image',
            input: {
              prompt: 'Featured image for blog post: {{loop.item}}'
            }
          }
        ]
      }
    },
    // Step 3: Publish to CMS
    {
      name: 'publish',
      type: 'LOOP',
      settings: {
        items: '{{steps.generate_posts.output}}',
        loopActions: [
          {
            pieceName: '@activepieces/piece-wordpress',
            actionName: 'create_post',
            input: {
              title: '{{loop.item.title}}',
              content: '{{loop.item.content}}',
              featuredImage: '{{loop.item.image}}'
            }
          }
        ]
      }
    }
  ]
}

AI SDK Integration

Activepieces uses the Vercel AI SDK (ai package) for AI operations:

import { streamText, generateText } from 'ai';
import { createAIModel } from './common/ai-sdk';

// Create AI model from provider config
const model = createAIModel({
  provider: AIProviderName.ANTHROPIC,
  model: 'claude-3-5-sonnet-20241022',
  apiKey: apiKey
});

// Generate text
const result = await generateText({
  model,
  prompt: 'What is Activepieces?',
  temperature: 0.7,
  maxTokens: 500
});

// Stream text (for real-time responses)
const stream = await streamText({
  model,
  prompt: 'Write a story...',
  temperature: 0.9
});

Agent Execution Flow

When an agent runs:

Parse prompt: Understand the task and goals
Plan approach: Decide which tools to use
Execute steps: Call tools iteratively
Evaluate results: Check if task is complete
Iterate if needed: Continue until success or max steps
Return output: Provide structured results

From the source code:

interface AgentTask {
  status: AgentTaskStatus;        // RUNNING, COMPLETED, FAILED
  steps: AgentStep[];             // Individual tool calls
  output?: AgentOutput;           // Final structured output
  error?: string;                 // Error if failed
}

enum AgentTaskStatus {
  RUNNING = 'RUNNING',
  COMPLETED = 'COMPLETED',
  FAILED = 'FAILED'
}

Best Practices

Clear Prompts

Write detailed, specific prompts. Include context, constraints, and expected output format.

Structured Output

Define structured output schemas so you can reliably use agent results in subsequent steps.

Limit Tools

Give agents only the tools they need. Too many tools can confuse the AI.

Test Iterations

Test with different prompts and tool combinations to find what works best.

Monitor Costs

AI API calls cost money. Monitor usage and optimize prompts to reduce token consumption.

Fallback Logic

Add error handling and fallback paths for when AI responses don’t meet expectations.

AI + MCP: Powerful Combination

Combine AI agents with MCP servers for ultimate flexibility:

Build flows with AI actions
Expose flows as MCP tools
Use in Claude Desktop/Cursor
AI assistants can call your AI-powered workflows

This creates a powerful cycle where:

AI assistants use your workflows
Your workflows use AI to be intelligent
Everything is connected through MCP

This is the future of automation: AI-powered workflows that are themselves accessible to AI assistants.
