Findings

Shared experience

100 / 100 · weight 30

passPage experience

weight 20

The page a person sees holds up next to the agent surface: a working interface, visible actions, readable content, nothing in the way.

passHuman parity

weight 10

The person co-browsing can see and use this page - the same page the agent's tools act on.

Task completion

100 / 100 · weight 25

passTool selection

weight 15

An agent chose an existing, callable tool and built a schema-valid call for all 3 canonical intents, each matching the kind of tool its intent needs. Nothing was executed, so this verifies selection, not outcomes.

not applicableCoverage vs. site type

weight 10

This tool set does not place the site in a category with a known expected tool shape, so there is no coverage baseline to score it against.

Tool quality

100 / 100 · weight 25

passRegistration timing

weight 1

Every measured tool registered within 419ms of navigation.

toolset_notebook

passCanonical entry point

weight 3

All 3 tools register on the canonical document.modelContext entry point.

passSchema validity

weight 4

All 3 declared input schemas are structurally valid object schemas.

passSchema quality

weight 4

All 2 of 3 tool schemas that declare parameters describe them (the other 1 declares no parameters), and every description stays within Chrome's size guidance.

passNaming quality

weight 2

All 3 tool names are consistent, verb-led, and within Chrome's size guidance.

passStub detection

weight 4

All 3 tools declare an execute handler.

passRegistration errors

weight 2

No tool registration threw during the capture.

passDescription quality

weight 5

All 3 rated tool descriptions say what the tool does, when to use it, and what it returns.

Trust

100 / 100 · weight 20

passAnnotations present

weight 6

All 1 read-shaped tool declares readOnlyHint: true - the one declared claim that lets an agent treat a call as safe to make without asking.

passAnnotation mismatch

weight 6

No tool claims to be read-only while its own name or description says it writes (1 declared hint checked).

not applicableUntrusted content hint

weight 4

No tool's contract suggests it returns text written by somebody other than the site, so there is nothing to flag as untrusted.

not applicableInjection surface

weight 4

No tool's metadata carries instruction-shaped text aimed at the agent reading it. This check only ever flags; it never credits a site.

Add the tools this site is missing

Our scanner reads your website and suggests the right WebMCP tools for it.

The open source webmcp plugin teaches your coding agent to audit a site, implement tools on document.modelContext, and verify them in a real browser. npx @ora-ai/webmcp-verify runs the verification on its own. No signup, no hosted service.
