Developer-platform lead: Skills are files; MCP needs hosting and auth. Agent builder: Load the skill, then call the tools it names. Agent Skills are SKILL.md instructions loaded by progressive disclosure. ## The sourced difference Agent Skills are SKILL.md instructions loaded by progressive disclosure; MCP servers expose callable tools. Vendors such as Stripe ship both and configure them together.

Registry in preview with API v0.1 frozen since 24 Oct 2025. | | What it does not do | Does not execute anything by itself or expose remote tools; skills are instructions and files, often paired with an MCP server or CLI. | Does not grade servers, verify registry entries, or prescribe a .well-known discovery file in the 2026-07-28 core spec; server cards are still Working Group work. | Read the full entries: [Agent Skills](https://agentmcpdirectory.com/standards/agent-skills/) and [MCP](https://agentmcpdirectory.com/standards/mcp/). ## Seen in the shared crawl | Path | Top 10,000 found | Ora leaderboard found | | --- | --- | --- | | /.well-known/agent-skills/index.json | 53 of 7,435 (0.71%) | 144 of 3,364 (4.28%) | A path counts only when the answer is the right kind of document.
