Claude Code:

claude mcp add --transport http arc-library https://uiarc.dev/api/mcp --header "Authorization: <YOUR_VALUE>"

Or add to your MCP client config:

{
  "mcpServers": {
    "arc-library": {
      "url": "https://uiarc.dev/api/mcp",
      "headers": {
        "Authorization": "<YOUR_VALUE>"
      }
    }
  }
}

• Authorization secret — Optional. "Bearer arc_pro_..." from uiarc.dev/account unlocks Arc Pro source. Free items work without it.
