warningHuman parity

0 / 8

11 of 11 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

63 / 100 · weight 50

passTools registered

4 / 4

11 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.

warningRegistration timing

2 / 4

The slowest tool took 1261ms to register, past the 1000ms an agent reading the registry at first paint would wait for.

toolaction_job_get

action_job_get: registered at 1261ms

fix

// Register tools as soon as they're ready, not behind a deferred/async chunk.
document.modelContext.provideContext({ tools: [/* ... */] });

passCanonical entry point

4 / 4

All 11 tools register on the canonical document.modelContext entry point.

passSchema validity

5 / 5

All 11 tools declare a structurally valid object input schema.

warningSchema quality

1.1 / 4

8 of 11 tool schemas are harder for an agent to use than they need to be: search_marketing_jobs declares no required list, so an agent cannot tell which parameters are mandatory.

toolsearch_marketing_jobs

search_marketing_jobs: declares no required list, so an agent cannot tell which parameters are mandatory; get_research_trackers: declares no required list, so an agent cannot tell which parameters are

fix

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

passStub detection

5 / 5

All 11 tools declare an execute handler.

warningAnnotations present

1.3 / 4

8 of 11 tools declare no readOnlyHint, so an agent cannot tell a read from a write without guessing from the name.

toolsubscribe_to_newsletter

subscribe_to_newsletter, action_company_get, action_digest_subscribe, action_job_get, action_jobs_search

fix

{
  name: "subscribe_to_newsletter",
  annotations: { readOnlyHint: true, destructiveHint: false, idempotentHint: true }
}

passAnnotation mismatch

3 / 3

No tool claims to be read-only while its name says it writes (3 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

11 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

68 / 100 · weight 30

warningNaming quality

1.4 / 2

Tool naming makes selection harder than it needs to be: 7 names do not start with a verb (action_company_get).

toolaction_company_get

fix

{ name: "action_company_get" /* 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.
