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

20 / 100 · weight 25
failTool selection
weight 15
An agent chose an existing tool and built a schema-valid call that held up on 0 of 3 canonical intents; on "Find a hotel in Lisbon for two nights in June." no tool on the page served it. Nothing was executed, so this verifies selection, not outcomes.
warningCoverage vs. site type
weight 10
The tool set covers 2 of the 4 things an agent needs on a travel site; it cannot book or hold a reservation or look up or change an existing booking.

passRegistration timing
weight 1
Every measured tool registered within 622ms of navigation.
toolreplace_charging_stop
passCanonical entry point
weight 3
All 7 tools register on the canonical document.modelContext entry point.
passSchema validity
weight 4
All 7 declared input schemas are structurally valid object schemas.
warningSchema quality
weight 4
4 of 7 tool schemas are harder for an agent to use than they need to be: find_chargers declares no required list, so an agent cannot tell which parameters are mandatory.
toolfind_chargers
find_chargers: declares no required list, so an agent cannot tell which parameters are mandatory; create_trip_plan: 1 parameter has no description (startingChargePercent); set_trip_preferences: 3 para
fix
{
  name: "find_chargers",
  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 (replace_charging_stop).
toolreplace_charging_stop
fix
{ name: "replace_charging_stop" /* short, unique, verb-based */ }
passStub detection
weight 4
All 7 tools declare an execute handler.
passRegistration errors
weight 2
No tool registration threw during the capture.
passDescription quality
weight 5
1 of 7 tool descriptions leave an agent guessing: list_vehicle_profiles Omits what comes back from the tool..
toollist_vehicle_profiles
list_vehicle_profiles: weak

Trust

100 / 100 · weight 20
passAnnotations present
weight 6
All 4 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 (7 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.

Our scanner reads your website and suggests the right WebMCP tools for it.
Reads the site's public pages; takes a few seconds.
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.
