Implementation Reference
- src/talk_to_figma_mcp/server.ts:651-679 (handler)Handler function that proxies the set_stroke_color command to the Figma plugin via sendCommandToFigma, including success/error responses.async ({ nodeId, r, g, b, a, weight }: any) => { try { const result = await sendCommandToFigma("set_stroke_color", { nodeId, color: { r, g, b, a: a || 1 }, weight: weight || 1, }); const typedResult = result as { name: string }; return { content: [ { type: "text", text: `Set stroke color of node "${typedResult.name }" to RGBA(${r}, ${g}, ${b}, ${a || 1}) with weight ${weight || 1}`, }, ], }; } catch (error) { return { content: [ { type: "text", text: `Error setting stroke color: ${error instanceof Error ? error.message : String(error) }`, }, ], }; } }
