Скачать или смотреть MCP OAuth Security: The One Thing Every Developer Gets Wrong

OAuth in Model Context Protocol (MCP) isn't what you think it is – and that confusion could break your agent's security.

In this snippet from our full deep dive on MCP OAuth security., we break down the critical distinction between MCP client-server authentication and downstream service authorization that's tripping up developers everywhere. When you add OAuth to MCP, you're NOT automatically getting Google Auth or Slack credentials built-in. You're solving a different (but equally important) problem.

Here's what we cover:

Why OAuth in MCP protects the server, not downstream APIs
The separation of concerns that keeps your agents secure
How token responsibility shifts between MCP clients and servers
Real examples of multi-service MCP servers and auth complexity
Why this architectural decision matters for production deployments

Whether you're building MCP servers or integrating them into your AI agents, understanding this distinction is crucial for secure, scalable implementations.
