Implementation Reference
- src/talk_to_figma_mcp/server.ts:604-643 (registration)MCP server.tool registration for 'set_fill_color' tool, including description, input schema, and handler function.// Set Fill Color Tool server.tool( "set_fill_color", "Set the fill color of a node in Figma can be TextNode or FrameNode", { nodeId: z.string().describe("The ID of the node to modify"), r: z.number().min(0).max(1).describe("Red component (0-1)"), g: z.number().min(0).max(1).describe("Green component (0-1)"), b: z.number().min(0).max(1).describe("Blue component (0-1)"), a: z.number().min(0).max(1).optional().describe("Alpha component (0-1)"), }, async ({ nodeId, r, g, b, a }) => { try { const result = await sendCommandToFigma("set_fill_color", { nodeId, color: { r, g, b, a: a || 1 }, }); const typedResult = result as { name: string }; return { content: [ { type: "text", text: `Set fill color of node "${typedResult.name }" to RGBA(${r}, ${g}, ${b}, ${a || 1})`, }, ], }; } catch (error) { return { content: [ { type: "text", text: `Error setting fill color: ${error instanceof Error ? error.message : String(error) }`, }, ], }; } } );
- src/talk_to_figma_mcp/server.ts:615-642 (handler)Handler function that proxies the set_fill_color command to the Figma plugin via WebSocket, formats success/error responses.async ({ nodeId, r, g, b, a }) => { try { const result = await sendCommandToFigma("set_fill_color", { nodeId, color: { r, g, b, a: a || 1 }, }); const typedResult = result as { name: string }; return { content: [ { type: "text", text: `Set fill color of node "${typedResult.name }" to RGBA(${r}, ${g}, ${b}, ${a || 1})`, }, ], }; } catch (error) { return { content: [ { type: "text", text: `Error setting fill color: ${error instanceof Error ? error.message : String(error) }`, }, ], }; } }
- Zod input schema validation for the set_fill_color tool parameters.{ nodeId: z.string().describe("The ID of the node to modify"), r: z.number().min(0).max(1).describe("Red component (0-1)"), g: z.number().min(0).max(1).describe("Green component (0-1)"), b: z.number().min(0).max(1).describe("Blue component (0-1)"), a: z.number().min(0).max(1).optional().describe("Alpha component (0-1)"), },
