set_corner_radius
Modify corner radius values on Figma design elements to adjust visual styling and create rounded edges for selected nodes.
Instructions
Set the corner radius of a node in Figma
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| nodeId | Yes | The ID of the node to modify | |
| radius | Yes | Corner radius value | |
| corners | No | Optional array of 4 booleans to specify which corners to round [topLeft, topRight, bottomRight, bottomLeft] |
Implementation Reference
- Handler function for the set_corner_radius tool. Destructures nodeId, radius, and optional corners parameters, calls sendCommandToFigma to delegate to the Figma plugin, and returns success/error messages.
async ({ nodeId, radius, corners }) => { try { const result = await sendCommandToFigma("set_corner_radius", { nodeId, radius, corners: corners || [true, true, true, true], }); const typedResult = result as { name: string }; return { content: [ { type: "text", text: `Set corner radius of node "${typedResult.name}" to ${radius}px`, }, ], }; } catch (error) { return { content: [ { type: "text", text: `Error setting corner radius: ${error instanceof Error ? error.message : String(error) }`, }, ], }; } } - Input schema using Zod validation for the set_corner_radius tool: nodeId (string), radius (number, min 0), corners (optional array of exactly 4 booleans).
