Talk to Figma MCP

Implementation Reference

• src/talk_to_figma_mcp/server.ts:1324-1366 (handler)

  The complete MCP tool registration, schema definition, and handler implementation for the 'set_corner_radius' tool. The handler forwards the nodeId, radius, and optional corners array to the Figma plugin via sendCommandToFigma, handles the response, and returns formatted content or error.

  server.tool(
    "set_corner_radius",
    "Set the corner radius of a node in Figma",
    {
      nodeId: z.string().describe("The ID of the node to modify"),
      radius: z.number().min(0).describe("Corner radius value"),
      corners: z
        .array(z.boolean())
        .length(4)
        .optional()
        .describe(
          "Optional array of 4 booleans to specify which corners to round [topLeft, topRight, bottomRight, bottomLeft]"
        ),
    },
    async ({ nodeId, radius, corners }: any) => {
      try {
        const result = await sendCommandToFigma("set_corner_radius", {
          nodeId,
          radius,
          corners: corners || [true, true, true, true],
        });
        const typedResult = result as { name: string };
        return {
          content: [
            {
              type: "text",
              text: `Set corner radius of node "${typedResult.name}" to ${radius}px`,
            },
          ],
        };
      } catch (error) {
        return {
          content: [
            {
              type: "text",
              text: `Error setting corner radius: ${error instanceof Error ? error.message : String(error)
                }`,
            },
          ],
        };
      }
    }
