Education Agent Skills Library An open source library of 165 evidence based pedagogical skills across 20 domains — works in Claude Code, Claude.ai (via MCP), OpenAI Codex, and Hermes Agent, and is engineered for AI agent orchestration. Domains 1–19 are teacher and designer facing. Domain 20 is the first student facing domain: live AI interaction patterns that shape how AI responds to learners during study sessions. [!IMPORTANT] Hosted MCP access now requires an auth token. The library is still free and open source, and local/plugin/manual use remains the recommended free path. The hosted MCP server is still available for people who specifically need a remote MCP endpoint, but anonymous access is now blocked so the service stays sustainable. Need hosted MCP? Request an access token or jump to hosted MCP setup. Get Started Works with Claude, Codex, Hermes Agent, and any tool that supports the Agent Skills standard. For sustainable free use, install or copy the skills locally from GitHub where possible. The hosted MCP server is a convenience endpoint for remote clients, not a requirement for using the library.
