Implementation Reference

• src/talk_to_figma_mcp/tools/document-tools.ts:141-168 (handler)

  The handler function that registers and implements the 'get_styles' tool. It calls sendCommandToFigma('get_styles') and returns the result as JSON.

  // Get Styles Tool
  server.tool(
    "get_styles",
    "Get all styles from the current Figma document",
    {},
    async () => {
      try {
        const result = await sendCommandToFigma("get_styles");
        return {
          content: [
            {
              type: "text",
              text: JSON.stringify(result)
            }
          ]
        };
      } catch (error) {
        return {
          content: [
            {
              type: "text",
              text: `Error getting styles: ${error instanceof Error ? error.message : String(error)}`,
            },
          ],
        };
      }
    }
  );

• src/talk_to_figma_mcp/tools/document-tools.ts:141-168 (registration)

  The tool is registered using `server.tool('get_styles', ...)` within the registerDocumentTools function. No additional schema is needed since it takes no parameters.

  // Get Styles Tool
  server.tool(
    "get_styles",
    "Get all styles from the current Figma document",
    {},
    async () => {
      try {
        const result = await sendCommandToFigma("get_styles");
        return {
          content: [
            {
              type: "text",
              text: JSON.stringify(result)
            }
          ]
        };
      } catch (error) {
        return {
          content: [
            {
              type: "text",
              text: `Error getting styles: ${error instanceof Error ? error.message : String(error)}`,
            },
          ],
        };
      }
    }
  );

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

  The sendCommandToFigma helper function sends the 'get_styles' command over WebSocket to the Figma plugin server and returns a promise that resolves with the response.

  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));
    });
  }
