Claude Skills vs. MCP: A Developer's Practical Boundary Question

A developer on r/ClaudeAI raises a practical question about tool integration boundaries after Claude Skills was released. The post describes how Skills made reasoning about MCP (Model Context Protocol) harder, not easier.
The Confusion Point
Before Skills, the story felt relatively clean: MCP was the serious path for structured external tool use, offering consistency and reuse despite more setup. Skills introduced a different perspective—sometimes a well-structured instruction layer gets you surprisingly far, and not every problem needs another protocol boundary.
Core Question
The developer isn't doubting MCP's usefulness but wants to understand where its value becomes decisive rather than just "nice to have." From the model's perspective, several things can look similar: it gets instructions, gets access to tools, performs actions, and returns outputs. The question is what specifically makes MCP the better fit for external systems versus simpler methods of guiding tool use.
Practical MCP Examples
The post mentions paying more attention to examples where MCP is used in practical, broader ways. Specifically:
- Latenode exposes workflows through MCP
- Latenode lets models connect to 1,200+ apps via MCP
This standardization argument feels more concrete than tiny one-off toy servers.
The Boundary Question
The developer's real question for people building around Claude is: "Where do you personally draw the line between 'this should just be handled with instructions/Skills' and 'this clearly benefits from MCP'?" The boundary still feels blurrier than people make it sound.
