WebMCP, the standard that lets AI agents use your site
Browser AI agents do not crawl a page the way a search bot does. They call the tools your site registers. We load your site in a real Chrome, intercept the modelContext API before the first page script runs, and show you exactly which tools end up available. Deferred, bundled and base64 encoded scripts included.
Runs in a real browser
A text search through HTML cannot see a registerTool() call inside a deferred or base64 encoded bundle. Our Chrome opens the page, scrolls it, simulates interaction and records every tool that genuinely registers.
Checks that follow the spec
We test only what the official Chrome documentation defines: toolname, tooldescription, toolparamdescription, the modelContext API and the origin trial token. No invented attributes.
Scoring we can defend
Community conventions such as the /.well-known/webmcp manifest are labelled unofficial and scored separately, as a bonus. Anything that cannot be checked remotely is stated as such rather than failed.
Why the other WebMCP checkers get it wrong
- WebMCP tools only exist inside a real browser tab. A scanner that does not execute JavaScript reports zero tools for sites that work perfectly.
- Performance plugins defer and base64 encode scripts, so searching the page source for registerTool finds nothing even when the tools work.
- There is no manifest, data-toolname or toolaction in the official spec. A checker that fails you on invented attributes is not checking anything real.
- While WebMCP is in origin trial, a valid token is exactly what makes tools work in stable Chrome. Almost nobody checks it. We decode it and confirm its origin and expiry.
