get_nodes_info

Instructions

Implementation Reference

• src/talk_to_figma_mcp/server.ts:292-325 (registration)

  Registration of the MCP tool 'get_nodes_info' with input schema (nodeIds: array of strings) and handler that fetches info for each node using underlying 'get_node_info' command and applies filtering.

  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:298-324 (handler)

  Handler function for get_nodes_info: iterates over nodeIds, calls sendCommandToFigma('get_node_info') for each, collects results, filters with filterFigmaNode, and returns as JSON text content.

  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:295-297 (schema)

  Input schema for get_nodes_info tool: requires nodeIds as array of strings.

  {
    nodeIds: z.array(z.string()).describe("Array of node IDs to get information about")
  },

• src/talk_to_figma_mcp/server.ts:202-289 (helper)

  Helper function filterFigmaNode used by the handler to process and clean Figma node data: skips VECTOR nodes, converts RGBA colors to hex, removes boundVariables and imageRef, recursively processes children.

  function filterFigmaNode(node: any) {
    // Skip VECTOR type nodes
    if (node.type === "VECTOR") {
      return null;
    }
  
    const filtered: any = {

      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;
          });
        }

        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,

      filtered.children = node.children
        .map((child: any) => filterFigmaNode(child))

    }
  
    return filtered;
  }

• src/talk_to_figma_mcp/server.ts:188-200 (helper)

  Helper function rgbaToHex to convert RGBA color objects to hex strings, used within filterFigmaNode.

  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')}`;
