The distinction between AI agent "Skills" and "MCP" (a wire protocol) is crucial for developers, as they operate at different layers of an agent's architecture. Skills provide cognitive scaffolding within the agent's context window to improve reasoning and embed specialized knowledge, while MCP enables agents to call external systems like APIs and databases. Both systems, launched by Anthropic and adopted by OpenAI, can extend an agent's capabilities, leading to common confusion. AI
