Talk to Figma MCP

Instructions

Implementation Reference

• src/talk_to_figma_mcp/server.ts:185-214 (registration)

  Registration of the MCP 'get_node_info' tool, including inline schema, description, and handler function that proxies to Figma plugin command and filters/returns node info as JSON.
  server.tool( "get_node_info", "Get detailed information about a specific node in Figma", { nodeId: z.string().describe("The ID of the node to get information about"), }, async ({ nodeId }) => { try { const result = await sendCommandToFigma("get_node_info", { nodeId }); return { content: [ { type: "text", text: JSON.stringify(filterFigmaNode(result)) } ] }; } catch (error) { return { content: [ { type: "text", text: `Error getting node info: ${error instanceof Error ? error.message : String(error) }`, }, ], }; } } );
• src/talk_to_figma_mcp/server.ts:191-214 (handler)

  The handler function executes the tool: sends 'get_node_info' command to Figma with nodeId parameter, processes result through filterFigmaNode, returns as markdown text content.
  async ({ nodeId }) => { try { const result = await sendCommandToFigma("get_node_info", { nodeId }); return { content: [ { type: "text", text: JSON.stringify(filterFigmaNode(result)) } ] }; } catch (error) { return { content: [ { type: "text", text: `Error getting node info: ${error instanceof Error ? error.message : String(error) }`, }, ], }; } } );
• src/talk_to_figma_mcp/server.ts:188-190 (schema)

  Input schema validation using Zod: requires 'nodeId' as string.
  { nodeId: z.string().describe("The ID of the node to get information about"), },
• 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 sensitive fields like boundVariables/imageRef, extracts relevant style properties, and processes children.
  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; }
