## Quick Start for Agents

### Option A: MCP Protocol (recommended for Claude Desktop, Cursor, Windsurf)

The MCP server provides 8 typed tools, 3 resources, and 2 prompts. No authentication required.

- Server card: `GET /.well-known/mcp.json` — full tool/resource/prompt descriptions
- Endpoint: `POST /mcp/` — Streamable HTTP transport
- Key tools: `search`, `get_video`, `list_videos`, `get_knowledge`, `get_essay`, `get_digest`, `get_latest_digest`, `list_tags`
- Key prompts: `research_ai_topic(topic)`, `daily_briefing()`

### Option B: REST API (HTTP agents)

1. `GET /skill.md` — read the full API reference (26 endpoints)
2. `GET /api/search?q={query}&agent=true` — search across all content types
3. `GET /api/knowledge` — list all AI concepts
4. `GET /api/knowledge/{slug}?agent=true` — fetch a concept with followable API links

Use `?agent=true` on detail endpoints to get markdown links rewritten as API URLs you can follow directly.
