Turn standard web forms into structured WebMCP tools that compatible browser agents can discover and fill. Auto WebMCP upgrades ordinary web forms into structured WebMCP tools for compatible browser agents. When you visit a page with a standard HTML form, the extension reads its labels, fields, choices, and validation rules, then exposes a structured tool through document.modelContext. An agent can discover that tool and fill many fields in one call instead of clicking through each control. It supports text fields, text areas, select menus, multi-selects, radio groups, checkboxes, dates, times, numbers, ranges, and forms added or updated by client-side apps. Auto WebMCP preserves forms that already provide their own WebMCP metadata. It ignores hidden, disabled, read-only, and file-upload controls. Everything runs locally in Chrome. There are no accounts, analytics, advertising, telemetry, or remote services. Auto WebMCP is open source: https://github.com/pauloportella/auto-webmcp-chrome Requires Chrome 149 or later and a compatible browser agent or client.
