When to use it
When you are writing your own MCP server to expose an internal system or third-party API to agents.
Caution
What it produces is an MCP server (a protocol endpoint), which is a different artifact from a skill; this site's glossary distinguishes the two. MCP SDK versions move fast — verify against current API after generation.
