4 findings

failCanonical entry point

0 / 4

Every tool registers through the deprecated navigator.modelContext alias; move them to document.modelContext before the alias is removed.

fix

// Use the canonical entry point - navigator.modelContext is deprecated.
document.modelContext.provideContext({ tools: [/* ... */] });

warningSchema quality

0 / 4

4 of 4 tool schemas are harder for an agent to use than they need to be: unifapi_get_agent_context declares no required list, so an agent cannot tell which parameters are mandatory.

unifapi_get_agent_context: declares no required list, so an agent cannot tell which parameters are mandatory; unifapi_find_skill: declares no required list, so an agent cannot tell which parameters ar

fix

{
  name: "unifapi_get_agent_context",
  inputSchema: {
    type: "object",
    properties: {
      query: { type: "string", description: "What to search for" }
    },
    required: ["query"]
  }
}

warningNaming quality

1 / 2

Tool naming makes selection harder than it needs to be: 4 names do not start with a verb (unifapi_get_agent_context).

fix

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

warningHuman parity

0 / 8

4 of 4 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.

unifapi_get_agent_context, unifapi_find_skill, unifapi_find_api, unifapi_fetch_machine_context

fix

<!-- Give the tool a visible counterpart: a declarative form is one the person can see and use too. -->
<form toolname="unifapi_get_agent_context" tooldescription="...">
  <!-- the same action, as UI -->
</form>

Findings

WebMCP use

62 / 100 · weight 50

passTools registered

4 / 4

4 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 532.5ms of navigation.

toolunifapi_find_api

failCanonical entry point

0 / 4

Every tool registers through the deprecated navigator.modelContext alias; move them to document.modelContext before the alias is removed.

toolunifapi_get_agent_context

fix

// Use the canonical entry point - navigator.modelContext is deprecated.
document.modelContext.provideContext({ tools: [/* ... */] });

passSchema validity

5 / 5

All 4 tools declare a structurally valid object input schema.

warningSchema quality

0 / 4

4 of 4 tool schemas are harder for an agent to use than they need to be: unifapi_get_agent_context declares no required list, so an agent cannot tell which parameters are mandatory.

  name: "unifapi_get_agent_context",

    type: "object",
    properties: {
      query: { type: "string", description: "What to search for" }
    },
    required: ["query"]
  }
}

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

The injection-surface model hop returned no usable result, so tool contracts were not reviewed for injection surface.

Usefulness

warningNaming quality

1 / 2

Tool naming makes selection harder than it needs to be: 4 names do not start with a verb (unifapi_get_agent_context).

fix

{ name: "unifapi_get_agent_context" /* 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.
