failAnnotations present

0 / 4

3 of 3 tools declare no readOnlyHint, so an agent cannot tell a read from a write without guessing from the name.

  annotations: { readOnlyHint: true, destructiveHint: false, idempotentHint: true }
}

warningHuman parity

0 / 8

3 of 3 tools run through the JavaScript API with no visible counterpart, so the person co-browsing cannot see what the agent is offered. Declarative forms (or at least a title annotation) close the gap.

Findings

WebMCP use

69 / 100 · weight 50

passTools registered

4 / 4

3 tools registered across 1 page.

failReal-browser eligible

0 / 8

The page's code registers these tools, but a real visitor's browser does not get them yet: WebMCP needs a native modelContext or a current origin trial token, and this page has neither.

passRegistration timing

4 / 4

Every measured tool registered within 327.5ms of navigation.

toolget_clueso_pricing

passCanonical entry point

4 / 4

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

passSchema validity

5 / 5

All 3 tools declare a structurally valid object input schema.

passSchema quality

4 / 4

All 3 tool schemas describe their parameters and stay within Chrome's size guidance.

passStub detection

5 / 5

All 3 tools declare an execute handler.

failAnnotations present

0 / 4

3 of 3 tools declare no readOnlyHint, so an agent cannot tell a read from a write without guessing from the name.

fix

{
  name: "search_clueso_site",
  annotations: { readOnlyHint: true, destructiveHint: false, idempotentHint: true }
}

not applicableAnnotation mismatch

0 / 3

No tool declares a readOnlyHint, so there is no safety claim to contradict.

not applicableUntrusted content hint

0 / 2

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

passRegistration errors

2 / 2

No tool registration threw during the capture.

warningToolchange coherence

1 / 2

3 tools were registered but the page never dispatched a toolchange event, so an agent subscribed to registry updates never learns they exist.

fix

document.modelContext.dispatchEvent(new Event("toolchange"));

not applicableInjection surface

0 / 3

No tool contract showed an obvious prompt-injection or unsafe-argument surface. This check only ever flags; it never credits a site.

Usefulness

79 / 100 · weight 30

passNaming quality

2 / 2

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

passDescription quality

6 / 6

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

warningTool selection

9.3 / 14

An agent completed 2 of 3 canonical intents against this tool set; on "Do the main action this site exists for." no tool on the page served it.

not applicableCoverage vs. site type

0 / 8

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.

passPage experience

12 / 12

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