Skills, Tools, and MCP are often discussed as if they were three competing ways to extend an AI agent. They are not. A Tool performs a concrete action. A Skill supplies a reusable method for completing a class of tasks. MCP is the protocol that lets an external server expose capabilities such as Tools to an agent application. An MCP Tool is therefore still a Tool; its distinguishing feature is where it comes from.

We tested those boundaries in a real xAgent session. The session loaded the deep-research Skill, connected to an MCP Server containing the official Model Context Protocol documentation, called two MCP Tools, wrote a report, and reopened the report for validation. The validation step also caught an inaccurate lifecycle description in the first draft and forced a correction.
