Full Analysis
  • [EXTERNAL_DOWNLOADS]: The skill instructs users to download a plugin.zip from a personal GitHub repository (TranHoaiHung/figma-ui-mcp). This source is not associated with the stated author (ara.so) or the verified vendor, posing a significant supply chain risk.
  • [REMOTE_CODE_EXECUTION]: The installation process uses npx figma-ui-mcp, which fetches and executes code from the NPM registry at runtime without version pinning or integrity checks.
  • [COMMAND_EXECUTION]: The skill provides shell commands for users to add the MCP server to various IDE configurations (Claude, Cursor, VS Code, Windsurf), leading to the execution of external code.
  • [DYNAMIC_EXECUTION]: The figma_write tool enables the agent to execute JavaScript operations directly within the Figma Desktop environment.
  • [INDIRECT_PROMPT_INJECTION]: The skill ingests data from Figma documents via figma_read (structured data and screenshots). Malicious instructions embedded in a Figma file could influence the agent's behavior.
  • Ingestion points: figma_read tool operations (e.g., get_design_context, get_selection) in SKILL.md.
  • Boundary markers: Absent; the agent is instructed to read designs as structured data without explicit delimiters or safety warnings for the ingested content.
  • Capability inventory: figma_write (JavaScript execution), file system access via the hosting IDE, and network communication via the local MCP bridge.
  • Sanitization: None specified for the data retrieved from the Figma API.
