2 of 2 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

77 / 100 · weight 50
passTools registered
4 / 4
2 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 171.79999995231628ms of navigation.
toolfilter_listings_by_price
passCanonical entry point
4 / 4
All 2 tools register on the canonical document.modelContext entry point.
passSchema validity
5 / 5
All 2 tools declare a structurally valid object input schema.
passSchema quality
4 / 4
All 2 tool schemas describe their parameters and stay within Chrome's size guidance.
passStub detection
5 / 5
All 2 tools declare an execute handler.
passAnnotations present
4 / 4
All 2 tools declare a readOnlyHint, so an agent knows which calls change state.
passAnnotation mismatch
3 / 3
No tool claims to be read-only while its name says it writes (2 declared hints checked).
warningUntrusted content hint
0 / 2
1 of 1 tools look like they return text written by other people but declare no untrustedContentHint, so an agent will treat the response as the site speaking.
toolfilter_listings_by_price
filter_listings_by_price: listing, user
fix
{ name: "filter_listings_by_price", annotations: { untrustedContentHint: true } }
passRegistration errors
2 / 2
No tool registration threw during the capture.
warningToolchange coherence
1 / 2
2 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
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.
