## For AI Agents — MCP Server & Product Feeds

LMK.today exposes an agentic commerce surface so AI assistants and crawlers can search, compare, and recommend products. It is differentiated from a raw affiliate feed by real price history, demand signals (most-wishlisted), curated cross-merchant search, and editorial collections. LMK is not the merchant of record — every product link resolves to an LMK product page, and outbound clicks are attributed/monetized via the /c/ handler.

- [AI Tools & MCP docs](https://lmk.today/mcp): Human- and machine-readable documentation of the full agentic surface
- [UCP discovery manifest](https://lmk.today/.well-known/ucp): Machine-readable manifest of the MCP endpoint, tools, and feeds
- **MCP endpoint**: `https://lmk.today/api/ucp/mcp` (Model Context Protocol over streamable HTTP)
