Show HN: Latch – Make any website usable by AI agents in one line (WebMCP)

Maps your contact / booking / signup fields into a tool an agent can fill and send.

Surfaces your main nav links so an agent can move around the site reliably.

Read-only discovery. If WebMCP isn't there, Latch does nothing and never breaks your page.

One static script. No MCP server to host, no API keys, no build step.

This page runs Latch on itself. Below is exactly what an AI agent now sees. Try the demo search and contact form — they're real, and Latch turned them into tools.

The script is free and open source forever. Pay only if you want the hosted dashboard that shows what agents actually do on your site.

Install free first — Pro shows your agent traffic, so upgrade from your dashboard once agents start visiting.

Analytics is opt-in and metadata-only: add data-key to your script tag and Latch reports tool name, outcome, and page path — never form contents, query strings, or PII. No key, and Latch makes zero network calls.
