Implementation Reference
- src/talk_to_figma_mcp/server.ts:646-686 (registration)MCP tool registration for 'set_stroke_color', including inline Zod schema for input parameters (nodeId, r, g, b, a, weight) and handler function that forwards the parameters to the Figma plugin via sendCommandToFigma and returns a success/error message.server.tool( "set_stroke_color", "Set the stroke color of a node in Figma", { 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)"), weight: z.number().positive().optional().describe("Stroke weight"), }, async ({ nodeId, r, g, b, a, weight }) => { 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: ${error instanceof Error ? error.message : String(error) }`, }, ], }; } } );
- src/talk_to_figma_mcp/server.ts:657-685 (handler)Handler function executes the tool logic by calling sendCommandToFigma with the stroke color parameters, processes the result from Figma plugin, and returns formatted text content indicating success or error.async ({ nodeId, r, g, b, a, weight }) => { try { const result = await sendCommandToFigma("set_stroke_color", { nodeId, color: { r, g, b, a: a || 1 }, weight: weight || 1, }); const typedResult = result as { name: string }; return { content: [ { type: "text", text: `Set stroke color of node "${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) }`, }, ], }; } }
- Zod schema defining input parameters for the set_stroke_color tool: nodeId (required string), r/g/b (required numbers 0-1), a (optional number 0-1), weight (optional positive number).{ 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)"), weight: z.number().positive().optional().describe("Stroke weight"), },
