set_paragraph_spacing

Instructions

Implementation Reference

• src/talk_to_figma_mcp/tools/text-tools.ts:342-376 (handler)

  The tool handler that registers the 'set_paragraph_spacing' MCP tool. It defines the Zod schema for nodeId (string) and paragraphSpacing (number) inputs, sends the command to Figma via sendCommandToFigma, and returns a success/error message.

  // Set Paragraph Spacing Tool
  server.tool(
    "set_paragraph_spacing",
    "Set the paragraph spacing of a text node in Figma",
    {
      nodeId: z.string().describe("The ID of the text node to modify"),
      paragraphSpacing: z.coerce.number().describe("Paragraph spacing value in pixels"),
    },
    async ({ nodeId, paragraphSpacing }) => {
      try {
        const result = await sendCommandToFigma("set_paragraph_spacing", {
          nodeId,
          paragraphSpacing
        });
        const typedResult = result as { name: string, paragraphSpacing: number };
        return {
          content: [
            {
              type: "text",
              text: `Updated paragraph spacing of node "${typedResult.name}" to ${typedResult.paragraphSpacing}px`
            }
          ]
        };
      } catch (error) {
        return {
          content: [
            {
              type: "text",
              text: `Error setting paragraph spacing: ${error instanceof Error ? error.message : String(error)}`
            }
          ]
        };
      }
    }
  );

• src/talk_to_figma_mcp/types/index.ts:77-77 (schema)

  The FigmaCommand type union member '"set_paragraph_spacing"' used for type-safe command dispatching.

  | "set_paragraph_spacing"

• src/talk_to_figma_mcp/tools/text-tools.ts:342-376 (registration)

  The tool is registered via server.tool('set_paragraph_spacing', ...) inside the registerTextTools function.

  // Set Paragraph Spacing Tool
  server.tool(
    "set_paragraph_spacing",
    "Set the paragraph spacing of a text node in Figma",
    {
      nodeId: z.string().describe("The ID of the text node to modify"),
      paragraphSpacing: z.coerce.number().describe("Paragraph spacing value in pixels"),
    },
    async ({ nodeId, paragraphSpacing }) => {
      try {
        const result = await sendCommandToFigma("set_paragraph_spacing", {
          nodeId,
          paragraphSpacing
        });
        const typedResult = result as { name: string, paragraphSpacing: number };
        return {
          content: [
            {
              type: "text",
              text: `Updated paragraph spacing of node "${typedResult.name}" to ${typedResult.paragraphSpacing}px`
            }
          ]
        };
      } catch (error) {
        return {
          content: [
            {
              type: "text",
              text: `Error setting paragraph spacing: ${error instanceof Error ? error.message : String(error)}`
            }
          ]
        };
      }
    }
  );

• src/talk_to_figma_mcp/utils/websocket.ts:238-297 (helper)

  The sendCommandToFigma utility function that sends the 'set_paragraph_spacing' command (and any command) over WebSocket to the Figma plugin server.

  export function sendCommandToFigma(
    command: FigmaCommand,
    params: unknown = {},
    timeoutMs: number = 300000
  ): Promise<unknown> {
    return new Promise((resolve, reject) => {
      // If not connected, try to connect first
      if (!ws || ws.readyState !== WebSocket.OPEN) {
        connectToFigma();
        reject(new Error("Not connected to Figma. Attempting to connect..."));
        return;
      }
  
      // Check if we need a channel for this command
      const requiresChannel = command !== "join";
      if (requiresChannel && !currentChannel) {
        reject(new Error("Must join a channel before sending commands"));
        return;
      }
  
      const id = uuidv4();
      const request = {
        id,
        type: command === "join" ? "join" : "message",
        ...(command === "join"
          ? { channel: (params as any).channel, sessionId: SESSION_ID }
          : { channel: currentChannel }),
        message: {
          id,
          command,
          params: {
            ...(params as any),
            commandId: id, // Include the command ID in params
          },
        },
      };
  
      // Set timeout for request
      const timeout = setTimeout(() => {
        if (pendingRequests.has(id)) {
          pendingRequests.delete(id);
          logger.error(`Request ${id} to Figma timed out after ${timeoutMs / 1000} seconds`);
          reject(new Error('Request to Figma timed out'));
        }
      }, timeoutMs);
  
      // Store the promise callbacks to resolve/reject later
      pendingRequests.set(id, {
        resolve,
        reject,
        timeout,
        lastActivity: Date.now()
      });
  
      // Send the request
      logger.info(`Sending command to Figma: ${command}`);
      logger.debug(`Request details: ${JSON.stringify(request)}`);
      ws.send(JSON.stringify(request));
    });
