Implementation Reference

• src/talk_to_figma_mcp/tools/text-tools.ts:378-411 (registration)

  MCP tool registration for 'set_text_case', including schema validation with Zod and handler that sends the command to Figma plugin and returns success/error message.

  server.tool(
    "set_text_case",
    "Set the text case of a text node in Figma",
    {
      nodeId: z.string().describe("The ID of the text node to modify"),
      textCase: z.enum(["ORIGINAL", "UPPER", "LOWER", "TITLE"]).describe("Text case type"),
    },
    async ({ nodeId, textCase }) => {
      try {
        const result = await sendCommandToFigma("set_text_case", {
          nodeId,
          textCase
        });
        const typedResult = result as { name: string, textCase: string };
        return {
          content: [
            {
              type: "text",
              text: `Updated text case of node "${typedResult.name}" to ${typedResult.textCase}`
            }
          ]
        };
      } catch (error) {
        return {
          content: [
            {
              type: "text",
              text: `Error setting text case: ${error instanceof Error ? error.message : String(error)}`
            }
          ]
        };
      }
    }
  );

• src/talk_to_figma_mcp/tools/text-tools.ts:385-410 (handler)

  Handler function for the 'set_text_case' tool that executes the logic by calling sendCommandToFigma and formats the response.

  async ({ nodeId, textCase }) => {
    try {
      const result = await sendCommandToFigma("set_text_case", {
        nodeId,
        textCase
      });
      const typedResult = result as { name: string, textCase: string };
      return {
        content: [
          {
            type: "text",
            text: `Updated text case of node "${typedResult.name}" to ${typedResult.textCase}`
          }
        ]
      };
    } catch (error) {
      return {
        content: [
          {
            type: "text",
            text: `Error setting text case: ${error instanceof Error ? error.message : String(error)}`
          }
        ]
      };
    }
  }

• src/talk_to_figma_mcp/tools/text-tools.ts:381-384 (schema)

  Input schema for 'set_text_case' tool using Zod: nodeId (string) and textCase (enum: ORIGINAL, UPPER, LOWER, TITLE).

  {
    nodeId: z.string().describe("The ID of the text node to modify"),
    textCase: z.enum(["ORIGINAL", "UPPER", "LOWER", "TITLE"]).describe("Text case type"),
  },

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

  'set_text_case' included in FigmaCommand type union for internal type safety when sending commands.
