The Model Context Protocol added a Skills extension (modelcontextprotocol/ext-skills). Servers declare io.modelcontextprotocol/skills; clients discover with skills/list, fetch metadata with skills/get, then load SKILL.md and supporting files via resources/read only when needed, instead of stuffing every skill into context. Spec: modelcontextprotocol.io/extensions/skills/overview.

Key Takeaways

  • ✓Official repo modelcontextprotocol/ext-skills, maintained by the Skills Over MCP Working Group.
  • ✓Flow: skills/list then skills/get then resources/read so SKILL.md loads on demand and saves context.
  • ✓Servers must declare resources plus io.modelcontextprotocol/skills; optional directoryRead for directory listing.
