• src/talk_to_figma_mcp/server.ts:320-354 (handler)

  The handler function registers the 'get_nodes_info' tool and implements its core logic: it accepts an array of nodeIds, fetches individual node information by calling sendCommandToFigma('get_node_info') for each ID in parallel using Promise.all, processes each result with filterFigmaNode, and returns a JSON string of the filtered node data or an error message.
  server.tool( "get_nodes_info", "Get detailed information about multiple nodes in Figma", { nodeIds: z.array(z.string()).describe("Array of node IDs to get information about") }, async ({ nodeIds }) => { try { const results = await Promise.all( nodeIds.map(async (nodeId) => { const result = await sendCommandToFigma('get_node_info', { nodeId }); return { nodeId, info: result }; }) ); return { content: [ { type: "text", text: JSON.stringify(results.map((result) => filterFigmaNode(result.info))) } ] }; } catch (error) { return { content: [ { type: "text", text: `Error getting nodes info: ${error instanceof Error ? error.message : String(error) }`, }, ], }; } } );
• src/talk_to_figma_mcp/server.ts:323-325 (schema)

  Zod input schema defining the required 'nodeIds' parameter as an array of strings.

• src/talk_to_figma_mcp/server.ts:230-317 (helper)

  Helper function filterFigmaNode recursively processes Figma node data: skips VECTOR nodes, converts RGBA colors to hex using rgbaToHex, removes boundVariables and imageRef, extracts relevant properties like fills, strokes, bounding box, style, characters, and children (filtered recursively). Used by both get_node_info and get_nodes_info tools to clean and standardize node information.
  function filterFigmaNode(node: any) { // Skip VECTOR type nodes if (node.type === "VECTOR") { return null; } const filtered: any = { id: node.id, name: node.name, type: node.type, }; if (node.fills && node.fills.length > 0) { filtered.fills = node.fills.map((fill: any) => { const processedFill = { ...fill }; // Remove boundVariables and imageRef delete processedFill.boundVariables; delete processedFill.imageRef; // Process gradientStops if present if (processedFill.gradientStops) { processedFill.gradientStops = processedFill.gradientStops.map((stop: any) => { const processedStop = { ...stop }; // Convert color to hex if present if (processedStop.color) { processedStop.color = rgbaToHex(processedStop.color); } // Remove boundVariables delete processedStop.boundVariables; return processedStop; }); } // Convert solid fill colors to hex if (processedFill.color) { processedFill.color = rgbaToHex(processedFill.color); } return processedFill; }); } if (node.strokes && node.strokes.length > 0) { filtered.strokes = node.strokes.map((stroke: any) => { const processedStroke = { ...stroke }; // Remove boundVariables delete processedStroke.boundVariables; // Convert color to hex if present if (processedStroke.color) { processedStroke.color = rgbaToHex(processedStroke.color); } return processedStroke; }); } if (node.cornerRadius !== undefined) { filtered.cornerRadius = node.cornerRadius; } if (node.absoluteBoundingBox) { filtered.absoluteBoundingBox = node.absoluteBoundingBox; } if (node.characters) { filtered.characters = node.characters; } if (node.style) { filtered.style = { fontFamily: node.style.fontFamily, fontStyle: node.style.fontStyle, fontWeight: node.style.fontWeight, fontSize: node.style.fontSize, textAlignHorizontal: node.style.textAlignHorizontal, letterSpacing: node.style.letterSpacing, lineHeightPx: node.style.lineHeightPx }; } if (node.children) { filtered.children = node.children .map((child: any) => filterFigmaNode(child)) .filter((child: any) => child !== null); // Remove null children (VECTOR nodes) } return filtered; }

  Utility function rgbaToHex converts Figma RGBA color objects to hexadecimal strings, omitting alpha if fully opaque. Used within filterFigmaNode for color normalization.
  function rgbaToHex(color: any): string { // skip if color is already hex if (color.startsWith('#')) { return color; } const r = Math.round(color.r * 255); const g = Math.round(color.g * 255); const b = Math.round(color.b * 255); const a = Math.round(color.a * 255); return `#${r.toString(16).padStart(2, '0')}${g.toString(16).padStart(2, '0')}${b.toString(16).padStart(2, '0')}${a === 255 ? '' : a.toString(16).padStart(2, '0')}`; }
