Chapter 8: Production Security and Operations

Welcome to Chapter 8: Production Security and Operations. In this part of Figma Context MCP Tutorial: Design-to-Code Workflows for Coding Agents, you will build an intuitive mental model first, then move into concrete implementation details and practical production tradeoffs.

This chapter covers secure deployment and operational policies for Figma context pipelines.

Security Checklist

• store Figma tokens in secret manager, not plain files
• scope token usage to required access only
• rotate credentials on schedule
• audit MCP requests and response metadata

Operational Metrics

Metric	Why It Matters
design-to-code success rate	outcome quality
average retries per screen	prompt/context quality signal
mean implementation latency	productivity and cost

Summary

You now have the security and operations baseline for running Figma Context MCP in production teams.

src/extractors/types.ts

The TraversalOptions interface in src/extractors/types.ts handles a key part of this chapter's functionality:

}

export interface TraversalOptions {
  maxDepth?: number;
  nodeFilter?: (node: FigmaDocumentNode) => boolean;
  /**
   * Called after children are processed, allowing modification of the parent node
   * and control over which children to include in the output.
   *
   * @param node - Original Figma node
   * @param result - SimplifiedNode being built (can be mutated)
   * @param children - Processed children
   * @returns Children to include (return empty array to omit children)
   */
  afterChildren?: (
    node: FigmaDocumentNode,
    result: SimplifiedNode,
    children: SimplifiedNode[],
  ) => SimplifiedNode[];
}

/**
 * An extractor function that can modify a SimplifiedNode during traversal.
 *
 * @param node - The current Figma node being processed
 * @param result - SimplifiedNode object being built—this can be mutated inside the extractor
 * @param context - Traversal context including globalVars and parent info. This can also be mutated inside the extractor.
 */
export type ExtractorFn = (
  node: FigmaDocumentNode,
  result: SimplifiedNode,
  context: TraversalContext,

This interface is important because it defines how Figma Context MCP Tutorial: Design-to-Code Workflows for Coding Agents implements the patterns covered in this chapter.

The SimplifiedDesign interface in src/extractors/types.ts handles a key part of this chapter's functionality:

) => void;

export interface SimplifiedDesign {

  componentSets: Record<string, SimplifiedComponentSetDefinition>;
  globalVars: GlobalVars;
}

export interface SimplifiedNode {
  id: string;
  name: string;
  type: string; // e.g. FRAME, TEXT, INSTANCE, RECTANGLE, etc.
  // text
  text?: string;
  textStyle?: string;
  // appearance
  fills?: string;
  styles?: string;
  strokes?: string;
  // Non-stylable stroke properties are kept on the node when stroke uses a named color style
  strokeWeight?: string;
  strokeDashes?: number[];
  strokeWeights?: string;
  effects?: string;
  opacity?: number;
  borderRadius?: string;
  // layout & alignment
  layout?: string;
  // for rect-specific strokes, etc.
  componentId?: string;
