Flows are built from nodes connected together. Each node type serves a specific purpose.

​
Core Nodes

​
START Node

Defines the flow’s input schema and trigger configuration.
  • Input Schema: JSON Schema defining accepted parameters
  • Trigger: Webhook, schedule, manual, or MCP tool

​
END Node

Defines the flow’s output schema.
  • Output Schema: JSON Schema defining return structure
  • Return Value: What the flow returns to callers

​
Action Nodes

​
HTTP Action

Make HTTP requests to external APIs.
  • Method: GET, POST, PUT, PATCH, DELETE
  • URL: Request URL (can use variables)
  • Headers: Custom headers
  • Body: Request body (for POST/PUT/PATCH)
  • Response: Access response data in subsequent nodes

​
Tool Action

Call other tools (including other flows).
  • Tool Selection: Choose from available tools
  • Parameters: Map flow variables to tool parameters
  • Response: Access tool response in subsequent nodes

​
Transform Node

Transform data between steps.
  • Input: Data from previous nodes
  • Transformations: JSONPath expressions, calculations
  • Output: Transformed data for next nodes

​
Condition Node

Branch logic based on conditions.
  • Condition: Expression to evaluate
  • True Path: Execute if condition is true
  • False Path: Execute if condition is false

​
Variable References

Reference data from previous nodes: 
{{node_name.field_name}}
{{START.input_param}}
{{http_action.response.data}}
