OpenCode MCP Figma Authentication

Skill by ara.so — Design Skills collection.

This skill enables authentication with Figma's MCP (Model Context Protocol) server for OpenCode and other AI agents. Figma MCP rejects non-whitelisted agents by default; this tool generates the required authentication file to bypass that restriction.

What It Does

OpenCode MCP Figma is a minimal authentication tool that:

• Connects to Figma's MCP server at https://mcp.figma.com/mcp
• Handles the OAuth-style authentication flow
• Generates an mcp-auth.json file with valid credentials
• Enables OpenCode and other AI agents to access Figma design data via MCP

This is specifically needed because Figma's MCP server has agent whitelisting that blocks OpenCode by default.
