Best Practices and Patterns

When to Use

When setting up a sustainable design-to-code workflow. These practices apply across all clients and server types.

Decision

Scenario Recommended approach
First session in a project Generate rules file first, validate on a simple component, then tackle complex frames
Complex multi-section page Generate each section individually, then assemble
Existing component library Set up Code Connect before generating any code
Design system with tokens Run get_variable_defs before first get_design_context call
Unfamiliar Figma file Run get_metadata to map structure before generating code

Pattern

Optimal session sequence: 

Session setup (once per project):
1. whoami → verify account and seat type
2. create_design_system_rules → save to rules/figma-rules.md
3. get_code_connect_suggestions → establish component mappings

Per-frame workflow:
1. get_screenshot → visual reference
2. get_variable_defs → token names
3. get_design_context → structured layout data
4. Generate code referencing tokens and mapped components
5. Validate output against screenshot

Large frame workflow:
1. get_metadata → identify node hierarchy and sub-node IDs
2. get_screenshot → visual reference for the full frame
3. get_design_context on specific sub-nodes → targeted extraction
4. Assemble generated sections

Performance Considerations

  • Each tool call counts against your rate limit — batch decisions before starting (know your framework, component paths, and output location before prompting)
  • get_design_context on deeply nested frames is the most expensive call — use get_metadata to scope before calling
  • Avoid calling get_screenshot + get_design_context + get_variable_defs separately when a single well-structured prompt triggers all three in sequence

Security Considerations

  • The MCP server accesses only Figma files your account has permission to view or edit — the server enforces Figma's own access controls
  • Personal access tokens (if used in older setups) should be stored as environment variables, never hardcoded in config files
  • OAuth authentication (current standard) is scoped to your Figma account — shared workstations should use separate authentication per user
  • Rules files committed to version control should not contain account-specific paths or credentials

Development Standards

  • Treat generated code as a starting draft — review for accessibility (ARIA roles, focus management, semantic HTML) before committing
  • Generated code rarely handles edge cases (empty states, error states, loading states) — add these manually
  • Do not generate code from low-fidelity wireframes — MCP output quality scales directly with design completeness
  • Run your linter/formatter on generated code before reviewing — auto-fix style issues before evaluating logic
