failAnnotations present

0 / 4

3 of 3 tools declare no readOnlyHint, so an agent cannot tell a read from a write without guessing from the name.

warningHuman parity

0 / 8

3 of 3 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.

<!-- Give the tool a visible counterpart: a declarative form is one the person can see and use too. -->

Findings

WebMCP use

66 / 100 · weight 50

passTools registered

4 / 4

3 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 616.4000000953674ms of navigation.

toolsearch_cfps

passCanonical entry point

4 / 4

All 3 tools register on the canonical document.modelContext entry point.

passSchema validity

5 / 5

All 3 tools declare a structurally valid object input schema.

warningSchema quality

2.7 / 4

1 of 3 tool schemas are harder for an agent to use than they need to be: generate_conference_names 1 parameter has no description (tone).

toolgenerate_conference_names

generate_conference_names: 1 parameter has no description (tone)

fix

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

passStub detection

5 / 5

All 3 tools declare an execute handler.

failAnnotations present

0 / 4

3 of 3 tools declare no readOnlyHint, so an agent cannot tell a read from a write without guessing from the name.

toolsearch_cfps

search_cfps, analyze_abstract, generate_conference_names

fix

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

not applicableAnnotation mismatch

0 / 3

No tool declares a readOnlyHint, so there is no safety claim to contradict.

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

3 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 3 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.
