28 of 42 tools declare no readOnlyHint, so an agent cannot tell a read from a write without guessing from the name.

warningHuman parity
0 / 8
42 of 42 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

63 / 100 · weight 50
passTools registered
4 / 4
42 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. The page does carry an origin-trial token, but it does not grant WebMCP on this origin.
passRegistration timing
4 / 4
Every measured tool registered within 362.5ms of navigation.
toolkarsilastirma_listesi
passCanonical entry point
4 / 4
All 42 tools register on the canonical document.modelContext entry point.
passSchema validity
5 / 5
All 42 tools declare a structurally valid object input schema.
warningSchema quality
1.1 / 4
30 of 42 tool schemas are harder for an agent to use than they need to be: ilan_ara 9 parameters have no description (q, kategori, fiyat_min, fiyat_max).
toolilan_ara
ilan_ara: 9 parameters have no description (q, kategori, fiyat_min, fiyat_max); ilan_detay: 1 parameter has no description (slug); marka_listele: declares no required list, so an agent cannot tell whi

}
passStub detection
5 / 5
All 42 tools declare an execute handler.
warningAnnotations present

}
passAnnotation mismatch
3 / 3
No tool claims to be read-only while its name says it writes (14 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.
failRegistration errors
0 / 2
16 tool registrations threw during the capture, so the registry an agent reads is incomplete.
duplicate tool name registered: ilan_ara
fix
try {
  document.modelContext.provideContext({ tools: [/* ... */] });
} catch (err) {
  console.error("WebMCP registration failed", err);
}
warningToolchange coherence
1 / 2
42 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

51 / 100 · weight 30
warningNaming quality
1 / 2
Tool naming makes selection harder than it needs to be: 41 names do not start with a verb (scan_images_c2pa).
toolscan_images_c2pa
fix
{ name: "scan_images_c2pa" /* short, unique, verb-based */ }
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.
