Better Code, Fewer Tokens: The Benefits of Code Connect in MCP | Figma Blog
Code Connect improves how coding agents translate Figma designs into production code by supplying real design-system components, imports, and prop values. Figma’s evaluations found that Code Connect reduced median task duration by 19.6%, lowered token usage by 29.5%, and increased code quality by one point on a 1–4 scale. The central conclusion is that better design-to-code context helps agents work faster while producing code that fits existing codebases. ## The Problem: Visually Correct but Technically Wrong Code - Without production context, agents often: - Rebuild interfaces from basic primitives. - Invent components that already exist. - Choose the wrong design-system component. - Spend extra tokens searching, debugging, and rewriting. - Figma’s MCP server normally provides a React representation of the design through `get_design_context`. - This output may match the visual design but does not explain how the design maps to a company’s actual component library. ## How Code Connect Enriches MCP Responses - Code Connect links Figma components to their real implementations in a codebase. - With Code Connect templates configured, MCP responses replace generic React markup with production-relevant snippets. - Agents receive: - Correct component imports. - Accurate component names. - Appropriate property values. - Code that reflects the company’s design system. - For example, generic markup for a tab control can be replaced with an existing component such as: ```tsx <SegmentedControl value="design" options={["Design", "Code"]} /> ``` ## Coinbase Case Study - Coinbase’s Design Systems team adopted Code Connect as engineers increasingly used coding agents. - Without Code Connect, agents sometimes fabricated alternatives, such as constructing a stepper from progress bars. - With Code Connect, agents received literal imports and accurate code representations for Coinbase Design System components. - Coinbase reported improved output quality and reduced token usage. ## Evaluation Results - Figma created an evaluation harness that ran identical design-to-code tasks: - Once without Code Connect. - Once with Code Connect templates. - The evaluation covered 27 test cases. - It measured: - Code quality. - Token consumption. - Task duration. - The tests used two React-based design systems: - Simple Design System (SDS), Figma’s example system. - Figma Pattern Library (FPL), a larger internal system. - Across the tests, Code Connect produced: - **19.6% lower median task duration** - **29.5% lower median token usage** - **A one-point increase in code quality on a 1–4 Likert scale** Teams using coding agents for design-to-code work should connect their Figma components to production implementations through Code Connect. Providing exact component context reduces guesswork and tokens while helping agents produce maintainable, design-system-compliant code.
