Add OAuth 2.1 authorization to MCP servers (Scalekit)

Goal

Secure an MCP server so only authenticated + authorized users (and approved MCP clients) can call your tools, using Scalekit as the OAuth 2.1 authorization server and your MCP server as the resource server.

When to activate this skill

Activate when the user asks to:

• "Add OAuth/OAuth 2.1/auth to my MCP server"
• "Implement .well-known/oauth-protected-resource"
• "Validate Bearer tokens / add middleware"
• "Enforce scopes per tool" / "least privilege for MCP tools"
• "Make my MCP server work with Claude Desktop / Cursor / VS Code auth"
