Implementation Reference

• src/talk_to_figma_mcp/tools/modification-tools.ts:155-181 (handler)

  The handler function that implements the core logic of the 'resize_node' tool. It invokes sendCommandToFigma to resize the specified node in Figma and returns a success or error message.

  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/tools/modification-tools.ts:150-154 (schema)

  Zod schema defining the input parameters for the 'resize_node' tool: nodeId (string), width (positive number), height (positive number).

  {
    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/tools/modification-tools.ts:147-182 (registration)

  The server.tool() call that registers the 'resize_node' tool on the MCP server, including its name, description, schema, and handler.

  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/tools/index.ts:16-16 (registration)

  registerModificationTools(server);

• src/talk_to_figma_mcp/server.ts:34-34 (registration)

  Top-level registration of all tools (including resize_node via chained calls) in the main server setup.

  registerTools(server);
