Implementation Reference

• src/cursor_mcp_plugin/code.js:521-549 (handler)

  Core handler function that implements the resize_node tool logic by fetching the Figma node and calling its resize method.

  async function resizeNode(params) {
    const { nodeId, width, height } = params || {};
  
    if (!nodeId) {
      throw new Error("Missing nodeId parameter");
    }
  
    if (width === undefined || height === undefined) {
      throw new Error("Missing width or height parameters");
    }
  
    const node = await figma.getNodeByIdAsync(nodeId);
    if (!node) {
      throw new Error(`Node not found with ID: ${nodeId}`);
    }
  
    if (!("resize" in node)) {
      throw new Error(`Node does not support resizing: ${nodeId}`);
    }
  
    node.resize(width, height);
  
    return {
      id: node.id,
      name: node.name,
      width: node.width,
      height: node.height,
    };
  }

• src/cursor_mcp_plugin/code.js:85-86 (registration)

  Dispatcher case in the command handler switch that routes 'resize_node' calls to the resizeNode function.

  case "resize_node":
    return await resizeNode(params);

• src/talk_to_figma_mcp/server.ts:379-410 (registration)

  MCP server tool registration for 'resize_node', including schema validation and proxy handler that forwards to Figma plugin.

  server.tool(
    "resize_node",
    "Resize a node in Figma",
    {
      nodeId: z.string().describe("The ID of the node to resize"),
      width: z.number().positive().describe("New width"),
      height: z.number().positive().describe("New height")
    },
    async ({ nodeId, width, height }) => {
      try {
        const result = await sendCommandToFigma('resize_node', { nodeId, width, height });
        const typedResult = result as { name: string };
        return {
          content: [
            {
              type: "text",
              text: `Resized node "${typedResult.name}" to width ${width} and height ${height}`
            }
          ]
        };
      } catch (error) {
        return {
          content: [
            {
              type: "text",
              text: `Error resizing node: ${error instanceof Error ? error.message : String(error)}`
            }
          ]
        };
      }
    }
  );

• src/talk_to_figma_mcp/server.ts:383-386 (schema)

  Input schema definition using Zod for the resize_node tool parameters.

    nodeId: z.string().describe("The ID of the node to resize"),
    width: z.number().positive().describe("New width"),
    height: z.number().positive().describe("New height")
  },

• src/talk_to_figma_mcp/server.ts:769-770 (helper)

  Type union including 'resize_node' command for Figma communication.
