Skills vs MCP, a false dichotomy

In the ongoing debate between using skills or MCP servers for AI agent extensions, the text argues that both are essential components of a comprehensive AI tooling strategy. Skills represent static, curated patterns or instructions that guide agents in executing tasks, while MCP servers provide live, authenticated access to systems and real-time data. By employing a two-layer architecture, organizations can ensure that skills offer judgment and expertise, while MCP servers grant the ability to interact with live services securely. The text emphasizes that this dual-layered approach avoids the pitfalls of relying solely on either skills or MCP servers, highlighting the importance of both in managing security, observability, and organizational governance. The future may see a convergence of skills with well-written documentation as AI agents improve in processing large documents, but the need for MCP servers to handle authentication and access to live systems will remain critical.
