Implement Design (Context MCP)

Overview

Use this skill to implement Figma designs with high fidelity by using Figma-Context-MCP (figma-developer-mcp) as the data source. Treat MCP output as design truth, then translate it into project conventions (components, tokens, styling, architecture).

Prerequisites

• Figma-Context-MCP server is configured and reachable in the current client
• User provides a Figma URL or explicit fileKey + nodeId
• A Figma personal access token is available (FIGMA_API_KEY)

Typical MCP server config (stdio)

{
  "mcpServers": {
    "Framelink MCP for Figma": {
      "command": "npx",
      "args": ["-y", "figma-developer-mcp", "--figma-api-key=YOUR-KEY", "--stdio"]
    }
  }
}

Required Workflow

Follow these steps in order.

Step 1: MCP Connectivity Probe (Required)

Before implementation, verify the MCP connection by calling get_figma_data directly.

Use the target node when available:

get_figma_data(fileKey="<fileKey>", nodeId="<nodeId>")

Success criteria:

• tool returns node data (metadata/layout/styles), even if partial/truncated
• no MCP transport/auth error

Failure handling:

• if call fails, stop implementation and report the exact error
• explicitly state that "enabled in config" may still mean "not connected in current session"
• ask user to fix MCP session/config/token, then retry probe

Step 2: Parse Figma Link

Extract from URL:

• fileKey: segment after /design/ or /file/
• nodeId: value of node-id query parameter

Convert nodeId to MCP-accepted format when needed:

• URL often gives 1-2
• tool accepts 1:2 and also supports -; both are generally valid

Step 3: Fetch Node Context with get_figma_data

Call:

get_figma_data(fileKey="<fileKey>", nodeId="<nodeId>")

Use output for:

• layout structure and auto layout rules
• typography and color styles
• component hierarchy and variants
• image/vector node references for asset extraction

If payload is too large:

• request target child node IDs from current result, then fetch child nodes individually with get_figma_data
• only use depth when the user explicitly asks for constrained traversal

Step 4: Download Assets with download_figma_images

When get_figma_data returns image/vector references, call:

download_figma_images(fileKey="<fileKey>", nodes=[...], localPath="<absolute-path>")

Rules:

• only use assets from Figma output
• do not replace with third-party icon packs
• use absolute paths for localPath
• preserve exported filenames and suffixes for traceability

Step 5: Translate to Project Conventions

• map Figma styles to existing design tokens
• replace generated/raw structures with project components
• keep framework idioms (state, routing, data flow, styling system)
• avoid hardcoded constants when token/component exists

Step 6: Achieve 1:1 Visual Fidelity

Validate against Figma node data and proportions:

• spacing and sizing
• typography (family, size, weight, line-height)
• colors, borders, radius, shadows
• interaction states
• responsive behavior

If exact parity conflicts with system constraints, keep system primitives and apply minimal targeted overrides.

Step 7: Final Validation Checklist

• layout and alignment match Figma
• text and typography match Figma
• colors/effects match Figma
• image/vector assets are complete and not substituted
• interactions and responsiveness are implemented
• accessibility baseline is preserved

Implementation Rules

• Reuse existing project components before creating new ones
• Keep components composable and typed
• Prefer tokenized values over literals
• Document intentional deviations briefly in code comments

Quick Example

User request:

Implement this page: https://figma.com/design/AbC12345XYZ/MyPage?node-id=10-22

Execution outline:

1. extract fileKey=AbC12345XYZ, nodeId=10-22
2. run MCP connectivity probe: get_figma_data(fileKey="AbC12345XYZ", nodeId="10-22")
3. if probe succeeds, fetch/expand node context with additional get_figma_data calls as needed
4. collect image/vector nodes from response
5. call download_figma_images(...) to project assets directory
6. implement with existing component system and tokens
7. verify fidelity and interaction behavior
