Rhys Sullivan proposes shipping agentic skills via MCP
Founder Rhys Sullivan questions the boundary between AI plugins, Model Context Protocol (MCP), and agentic skills, proposing that MCP servers should directly bundle and distribute skills to create a standard, client-agnostic capability model. This integration would simplify client-side setup by allowing servers to deliver both connection APIs and workflow instructions concurrently.
Bundling execution instructions directly into the data transport layer simplifies deployment but violates core modularity principles.
* **Separation of Concerns:** MCP acts as the transport layer for tool access, whereas skills represent subjective behavioral guidelines; tying them together limits customizability.
* **Context Window Efficiency:** Shipping extensive prompts within the protocol layer risks bloating context windows during tool discovery.
* **Security Control:** Keeping APIs separate from instructions preserves clear boundaries for access permissions and safety guardrails.
