create_expression
Creates a math expression node that computes a value from input variables.
Tool Overview & Agent Execution
create_expression is an official Exode MCP tool that allows AI coding assistants like Claude Code, Cursor, and Windsurf to creates a math expression node that computes a value from input variables.. It directly inspects and modifies local .exode JSON files with precision without manual UI tweaking.
Example Prompt for Claude Code & Cursor
Give this instruction to your AI coding agent to execute this tool on your active .exode workspace:
prompt
"Use create_expression to configure the motion properties in my active .exode workspace"Tool Parameters & Input Schema
| Parameter | Type | Required | Description |
|---|---|---|---|
| expression | string | Yes | JS expression using input variable names (e.g. 'scrollX * 0.5 + offset)' |
| name | string | Optional | The name parameter for create_expression. |
| outputType | string | Optional | Output type (default: number) |
| path | string | Yes | The path parameter for create_expression. |
| variables | array | Yes | Variable IDs to use as inputs |
| x | number | Optional | The x parameter for create_expression. |
| y | number | Optional | The y parameter for create_expression. |

add_behavior
Adds a behavioral sensor (Proximity, Magnetic, Fluid, Sticky, etc) to an object for interactive motion.
add_flow_rule
RECOMMENDED SEQUENCING PRIMITIVE: Adds an animation flow/sequencer rule to orchestrate multi-step transitions and state-driven animations without raster effects.
add_input
RECOMMENDED STATE MACHINE PRIMITIVE: Adds a reactive input variable (Boolean, Number, Trigger, Text) to the state machine to model component states without heavy raster effects.
add_input_variable
RECOMMENDED STATE MACHINE PRIMITIVE (Alias for add_input): Adds a reactive state machine variable to cleanly drive interactive states.
Build & Review Motion Visually
Let Claude or Cursor run create_expression, then fine-tune timing, spring physics, and export ready-to-ship code in ExodeUI.
