Implementation Reference

• src/talk_to_figma_mcp/tools/document-tools.ts:45-66 (handler)

  The core handler function for the 'get_selection' tool. It sends the 'get_selection' command to the Figma plugin using sendCommandToFigma and returns the result as JSON-formatted text content. Includes try-catch for error handling.

  async () => {
    try {
      const result = await sendCommandToFigma("get_selection");
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(result)
          }
        ]
      };
    } catch (error) {
      return {
        content: [
          {
            type: "text",
            text: `Error getting selection: ${error instanceof Error ? error.message : String(error)}`,
          },
        ],
      };
    }
  }

• src/talk_to_figma_mcp/tools/document-tools.ts:41-67 (registration)

  The registration of the 'get_selection' tool using server.tool(), specifying name, description, empty input schema ({}), and the handler function. This is called within registerDocumentTools.

  server.tool(
    "get_selection",
    "Get information about the current selection in Figma",
    {},
    async () => {
      try {
        const result = await sendCommandToFigma("get_selection");
        return {
          content: [
            {
              type: "text",
              text: JSON.stringify(result)
            }
          ]
        };
      } catch (error) {
        return {
          content: [
            {
              type: "text",
              text: `Error getting selection: ${error instanceof Error ? error.message : String(error)}`,
            },
          ],
        };
      }
    }
  );

• src/talk_to_figma_mcp/tools/index.ts:14-14 (registration)

  Call to registerDocumentTools from the main registerTools function, which performs the tool registrations including get_selection.

  registerDocumentTools(server);

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

  Invocation of registerTools(server) in the main server setup, which chains to the registration of get_selection.

  The 'get_selection' command is included in the FigmaCommand type union, used for type safety in command handling.
