4.8 / 8

4 of 5 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.

get_portfolio_data, get_project_details, get_candidate_profile, get_agent_guide

Findings

WebMCP use

80 / 100 · weight 50

passTools registered

4 / 4

4 imperative tools and 1 declarative form 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. The 1 declarative form tool on the page stay usable regardless.

passRegistration timing

4 / 4

Every measured tool registered within 68.79999999888241ms of navigation. 1 further tool carried no measurable registration time.

toolget_project_details

passCanonical entry point

4 / 4

All 4 tools register on the canonical document.modelContext entry point.

passSchema validity

5 / 5

All 4 tools declare a structurally valid object input schema.

passSchema quality

4 / 4

All 5 tool schemas describe their parameters and stay within Chrome's size guidance.

passStub detection

5 / 5

All 4 tools declare an execute handler.

passAnnotations present

4 / 4

All 4 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 (4 declared hints checked).

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

4 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

99 / 100 · weight 30

warningNaming quality

1.8 / 2

Tool naming makes selection harder than it needs to be: 1 name does not start with a verb (copy_mcp_endpoint).

toolcopy_mcp_endpoint

fix

{ name: "copy_mcp_endpoint" /* short, unique, verb-based */ }

passDescription quality

6 / 6

All 5 rated tool descriptions say what the tool does, when to use it, and what it returns.

passTool selection

14 / 14

An agent picked the right tool and built a valid call for all 3 canonical intents.

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.
