Findings

Shared experience

100 / 100 · weight 30

not applicableVisible effect

weight 6

Not invoked on this run: this audit did not call any tool. Scheduled re-audits only read the registry; a live audit from the report page calls the tools that declare readOnlyHint: true.

passPage experience

weight 16

The page a person sees holds up next to the agent surface: a working interface, visible actions, readable content, nothing in the way.

passHuman parity

weight 8

The person co-browsing can see and use this page - the same page the agent's tools act on, and 1 declarative form doubles as visible counterparts.

not applicableInvoke success rate

weight 6

Not invoked on this run: this audit did not call any tool. Scheduled re-audits only read the registry; a live audit from the report page calls the tools that declare readOnlyHint: true.

failTool selection

weight 12

An agent chose an existing tool and built a schema-valid call that held up on 1 of 3 canonical intents; on "Show me everything on that record." no tool on the page served it. Nothing was executed, so this verifies selection, not outcomes.

warningCoverage vs. site type

weight 7

The tool set covers 2 of the 4 things an agent needs on a saas site; it cannot create a record or start a job or update or move an existing record.

passRegistration timing

weight 1

Every measured tool registered within 649ms of navigation. 1 further tool carried no measurable registration time.

toolvertodigital_get_contact

passCanonical entry point

weight 3

All 13 tools register on the canonical document.modelContext entry point.

passSchema validity

weight 4

All 13 declared input schemas are structurally valid object schemas.

warningSchema quality

weight 4

5 of 14 tool schemas are harder for an agent to use than they need to be: vertodigital_get_site_index 1 parameter description is over Chrome's 150-character guidance.

toolvertodigital_get_site_index

vertodigital_get_site_index: 1 parameter description is over Chrome's 150-character guidance; vertodigital_get_page: 1 parameter description is over Chrome's 150-character guidance; vertodigital_searc

fix

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

warningNaming quality

weight 2

Tool naming makes selection harder than it needs to be: 1 name is over Chrome's 30-character guidance; 8 names do not start with a verb (why_verto).

toolvertodigital_search_case_studies

fix

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

passStub detection

weight 4

All 13 tools declare an execute handler.

passRegistration errors

weight 2

No tool registration threw during the capture.

passDescription quality

weight 5

1 of 14 tool descriptions leave an agent guessing: contact_verto Does not specify what information is sent or what is returned..

toolcontact_verto

contact_verto: weak

Trust

76 / 100 · weight 20

passAnnotations present

weight 5

All 6 read-shaped tools declare readOnlyHint: true - the one declared claim that lets an agent treat a call as safe to make without asking.

passAnnotation mismatch

weight 5

No tool claims to be read-only while its own name or description says it writes (7 declared hints checked).

warningUntrusted content hint

weight 3

1 of 1 tools look like they return text written by other people but declare no untrustedContentHint, so an agent will treat the response as the site speaking.

toolcontact_verto

contact_verto: review, message, replie

fix

{ name: "contact_verto", annotations: { untrustedContentHint: true } }

not applicableHint vs. observed

weight 4

Not invoked on this run: this audit did not call any tool. Scheduled re-audits only read the registry; a live audit from the report page calls the tools that declare readOnlyHint: true.

not applicableInjection surface

weight 3

No tool's metadata carries instruction-shaped text aimed at the agent reading it. This check only ever flags; it never credits a site.

Add the tools this site is missing

Our scanner reads your website and suggests the right WebMCP tools for it.

The open source webmcp plugin teaches your coding agent to audit a site, implement tools on document.modelContext, and verify them in a real browser. npx @ora-ai/webmcp-verify runs the verification on its own. No signup, no hosted service.
