Which AI hosts support this authentication flow?

Once implemented, your MCP server will support authenticated access from Claude Desktop, Cursor, VS Code, and other MCP-compliant hosts that support the OAuth flow.

What programming languages are supported?

The skill provides detailed implementation patterns and SDK examples for both Node.js (Express) and Python (FastAPI/FastMCP).

Can I restrict access to specific tools within my MCP server?

Yes, the skill includes guidance on implementing scope-based authorization, allowing you to define specific permissions (like read/write) for individual tools.

Does this work with standard stdio MCP servers?

No, OAuth 2.1 requires HTTP-based transport (Streamable HTTP). This skill provides specific instructions on how to migrate your server from stdio to HTTP.

Do I need a Scalekit account to use this skill?

Yes, this skill utilizes Scalekit to provide production-ready authentication infrastructure, including dynamic client registration and token validation.

Security & Testing

Secures Model Context Protocol (MCP) servers with production-ready OAuth 2.1 authorization using Scalekit.

The MCP OAuth Integration skill streamlines the process of adding robust authentication to MCP servers, enabling secure access for AI hosts like Claude Desktop, Cursor, and VS Code. It provides step-by-step guidance for migrating from stdio to HTTP-based transport, implementing mandatory discovery endpoints, and setting up token validation middleware using Scalekit's SDK. This skill is essential for developers moving from local MCP experimentation to production-grade, multi-tenant, or enterprise-ready AI tool deployments that require fine-grained, scope-based access control.
