Latch

Latch is a static JavaScript tool that exposes website elements as actions for AI agents.

Latch is a static JavaScript script that makes websites usable by AI agents and AI browsers. By pasting a single line of code before the body closing tag, site owners expose search, cart, forms, and navigation links as WebMCP tools. The script operates entirely on the frontend with zero dependencies and no backend server required. It reads the page in read-only mode and degrades silently where WebMCP is not present. The tool is designed for developers who want to support AI agent interactions without rewriting their backend or hosting an MCP server. Pricing includes a free open-source script tier and a paid Pro plan for hosted analytics dashboards.
