# MCP quickstart with AI coding agents

Use AI coding agents like Claude Code, GitHub Copilot CLI, Cursor, and OpenCode to add Scalekit's OAuth 2.1 authentication to your MCP servers. This guide shows you how to configure these agents so they analyze your codebase, apply consistent authentication patterns, and generate production-ready code that integrates OAuth 2.1 end-to-end, reduces implementation time from hours to minutes, and follows security best practices.

**Prerequisites**

- A [Scalekit account](https://app.scalekit.com) with MCP server management access
- Basic familiarity with OAuth 2.1 and MCP server architecture
- Terminal access for installing coding agent tools

  ## Next steps

Your MCP server now has OAuth 2.1 authentication integrated. Test the implementation with your MCP host to verify the authentication flow works correctly.

### Test with MCP hosts

Connect your authenticated MCP server to any MCP-compatible host:

- **Claude Desktop or Claude Code**: Configure the MCP server connection in settings
- **Cursor**: Add the MCP server to your workspace configuration
- **Windsurf**: Register the server in your MCP settings
- **Other MCP hosts**: Follow your host's documentation for connecting authenticated MCP servers

When you connect, the host authenticates using the OAuth 2.1 flow you configured. Verify that protected MCP resources require valid access tokens and that the discovery endpoint provides correct OAuth metadata.
