Findings

Shared experience

88 / 100 · weight 30

passPage experience

weight 20

1 of 4 page-experience marks came back short: obstruction A small overlay is present at the bottom left of the screen..

obstruction: weak

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

30 / 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 the record for a company called Northwind." 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 3 of the 4 things an agent needs on a saas site; it cannot create a record or start a job.

passRegistration timing

weight 1

Every measured tool registered within 624ms of navigation.

toolupdate_task_progress

passCanonical entry point

weight 3

All 6 tools register on the canonical document.modelContext entry point.

passSchema validity

weight 4

All 6 declared input schemas are structurally valid object schemas.

warningSchema quality

weight 4

5 of 6 tool schemas are harder for an agent to use than they need to be: list_ready_tasks 1 parameter has no description (capabilities).

toollist_ready_tasks

list_ready_tasks: 1 parameter has no description (capabilities); claim_task: 2 parameters have no description (agentId, taskId); update_task_progress: 7 parameters have no description (agentId, taskId

fix

{
  name: "list_ready_tasks",
  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: 2 names do not start with a verb (claim_task).

toolclaim_task

fix

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

passStub detection

weight 4

All 6 tools declare an execute handler.

passRegistration errors

weight 2

No tool registration threw during the capture.

passDescription quality

weight 5

All 6 rated tool descriptions say what the tool does, when to use it, and what it returns.

Trust

75 / 100 · weight 20

passAnnotations present

weight 6

All 2 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 (6 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.

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.
