Summary

A free tool called Skill Retrieval MCP acts as a search engine for AI skills, pulling from over 80,000 options sourced from Anthropic's guides and the community. Instead of cramming every skill into an AI's context window, the agent searches for what it needs and pulls just that skill's full context on demand.

Core ideas

One context card plus 6 ideas

The core problem: You can't fit 89,000 skills into an AI's context window at once. It's a hard technical limit, not a design choice.
Search over storage: Skill Retrieval MCP solves this by letting the agent search for relevant skills first, then load only the full context of what matches the request.
Source of skills: The 80,000 plus skills come from Anthropic's own guides combined with community contributions, not a single closed library.
No more building from scratch: The pitch is that you skip manually teaching an AI new skills since the retrieval system already has a massive pre built pool to pull from.
On demand context loading: The agent only pulls what it needs, when it needs it, which keeps the interaction efficient instead of bloated.
Free access: The tool itself costs nothing to use, based on how it's presented.
