Findings

Shared experience

100 / 100 · weight 30

passPage experience

weight 20

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 10

The person co-browsing can see and use this page - the same page the agent's tools act on.

Task completion

100 / 100 · weight 25

passTool selection

weight 15

An agent chose an existing, callable tool and built a schema-valid call for all 3 canonical intents, each matching the kind of tool its intent needs. Nothing was executed, so this verifies selection, not outcomes.

passCoverage vs. site type

weight 10

The tool set covers the whole core docs flow: search or browse the catalog, read a page or article, navigate the documentation tree.

Tool quality

92 / 100 · weight 25

passRegistration timing

weight 1

Every measured tool registered within 263ms of navigation.

toolcheck_freightbox_capability

passCanonical entry point

weight 3

All 9 tools register on the canonical document.modelContext entry point.

passSchema validity

weight 4

All 9 declared input schemas are structurally valid object schemas.

warningSchema quality

weight 4

4 of 9 tool schemas are harder for an agent to use than they need to be: read_freightbox_page declares no required list, so an agent cannot tell which parameters are mandatory.

toolread_freightbox_page

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

fix

{
  name: "read_freightbox_page",
  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 does not start with a verb (navigate_freightbox_site).

toolnavigate_freightbox_site

fix

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

passStub detection

weight 4

All 9 tools declare an execute handler.

passRegistration errors

weight 2

No tool registration threw during the capture.

passDescription quality

weight 5

All 9 rated tool descriptions say what the tool does, when to use it, and what it returns.

Trust

100 / 100 · weight 20

passAnnotations present

weight 6

All 8 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 6

No tool claims to be read-only while its own name or description says it writes (9 declared hints checked).

not applicableUntrusted content hint

weight 4

No tool's contract suggests it returns text written by somebody other than the site, so there is nothing to flag as untrusted.

not applicableInjection surface

weight 4

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.
