Findings

WebMCP use

100 / 100 · weight 50
passTools registered
4 / 4
2 tools registered across 1 page.
passReal-browser eligible
8 / 8
2 declarative form tools need no JavaScript API at all, so a real browser can use them as they are.
not applicableRegistration timing
0 / 4
No tool carried a measurable registration time, so how quickly this page's registry settles cannot be scored.
not applicableCanonical entry point
0 / 4
No tool is registered through the JavaScript API, so there is no entry point to score.
not applicableSchema validity
0 / 5
Declarative form tools carry their inputs as form fields rather than a JSON Schema, so there is no schema to validate.
passSchema quality
4 / 4
All 2 tool schemas describe their parameters and stay within Chrome's size guidance.
not applicableStub detection
0 / 5
Every tool on this page is a declarative form, which the browser submits itself, so there is no execute handler to check.
not applicableAnnotations present
0 / 4
Declarative form tools have nowhere to declare behaviour hints, so there are no annotations to score.
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.
not applicableToolchange coherence
0 / 2
Declarative form tools live in the markup and never announce a registry change, so there is no toolchange behaviour to score.
not applicableInjection surface
0 / 3
The injection-surface model hop returned no usable result, so tool contracts were not reviewed for injection surface.

Usefulness

100 / 100 · weight 30
passNaming quality
2 / 2
All 2 tool names are consistent, verb-led, and within Chrome's size guidance.
not applicableDescription quality
0 / 6
The description-quality model hop returned no usable result, so descriptions were not rated.
not applicableTool selection
0 / 14
The tool-selection model hop returned no usable result.
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.

Human experience

100 / 100 · weight 20
passHuman parity
8 / 8
All 2 tools are declarative forms, so the person co-browsing sees the same affordances the agent gets.
not applicablePage experience
0 / 12
The page-experience model hop returned no usable result, so the page was not graded.

Tool selection

The tool-selection model hop returned no usable result.
