Implementation Reference

• src/talk_to_figma_mcp/tools/component-tools.ts:20-46 (handler)

  The async handler function that sends the 'create_component_instance' command to Figma using sendCommandToFigma and processes the response or error.

  async ({ componentKey, x, y }) => {
    try {
      const result = await sendCommandToFigma("create_component_instance", {
        componentKey,
        x,
        y,
      });
      const typedResult = result as any;
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(typedResult),
          }
        ]
      }
    } catch (error) {
      return {
        content: [
          {
            type: "text",
            text: `Error creating component instance: ${error instanceof Error ? error.message : String(error)}`,
          },
        ],
      };
    }
  }

• src/talk_to_figma_mcp/tools/component-tools.ts:15-19 (schema)

  Input schema defined with Zod for validating the tool parameters: componentKey (string), x (number), y (number).

  {
    componentKey: z.string().describe("Key of the component to instantiate"),
    x: z.number().describe("X position"),
    y: z.number().describe("Y position"),
  },

• src/talk_to_figma_mcp/tools/component-tools.ts:12-47 (registration)

  Registration of the 'create_component_instance' tool on the MCP server using server.tool(), including name, description, schema, and handler.

  server.tool(
    "create_component_instance",
    "Create an instance of a component in Figma",
    {
      componentKey: z.string().describe("Key of the component to instantiate"),
      x: z.number().describe("X position"),
      y: z.number().describe("Y position"),
    },
    async ({ componentKey, x, y }) => {
      try {
        const result = await sendCommandToFigma("create_component_instance", {
          componentKey,
          x,
          y,
        });
        const typedResult = result as any;
        return {
          content: [
            {
              type: "text",
              text: JSON.stringify(typedResult),
            }
          ]
        }
      } catch (error) {
        return {
          content: [
            {
              type: "text",
              text: `Error creating component instance: ${error instanceof Error ? error.message : String(error)}`,
            },
          ],
