Claude Skills vs MCP

Different jobs

MCP is about reach: reading your files, searching a database, or sending a message through another service. A Skill is about method: the steps, format and standards for a task.

Using them together

Say you want a weekly sales report. An MCP server can fetch the numbers from your database. A Skill can say how to lay out the report and what to highlight.

Which should I make?

If Claude needs access it does not have, you need MCP. If Claude has access but does the task differently every time, write a Skill. A plain prompt is enough for a one-off request.

Key takeaways

  • MCP is access; Skills are know-how.
  • They combine well in one workflow.
  • Use a plain prompt for one-off tasks.

Quick questions

Can a Skill replace MCP?

Only if no outside access is needed. A skill alone cannot reach services Claude is not connected to.

Is a Skill the same as a custom prompt?

It is similar, but it can include files and scripts, and Claude loads it only when relevant.

Do I need both?

Not always. Start with whichever matches your gap: access or method.
