scan_images_c2pa

Scan every <img> on the current page for C2PA Content Credentials (content provenance metadata) and return a per-image summary: whether a manifest is present, the claim generator (the tool that produced or edited the image), the title, and the signer name. Use this to find which images on a page carry provenance data. Note: provenance is decoded but NOT cryptographically verified.Takes an action on the site.

3 findings

warningNaming quality

1.8 / 2

Tool naming makes selection harder than it needs to be: 2 names do not start with a verb (scan_images_c2pa).

fix

{ name: "scan_images_c2pa" /* short, unique, verb-based */ }

failAnnotations present

0 / 4

10 of 10 tools declare no readOnlyHint, so an agent cannot tell a read from a write without guessing from the name.

scan_images_c2pa, inspect_image_c2pa, list_models, estimate_credit_cost, search_articles

fix

{
  name: "scan_images_c2pa",
  annotations: { readOnlyHint: true, destructiveHint: false, idempotentHint: true }
}

warningHuman parity

0 / 8

10 of 10 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.

Findings

WebMCP use

63 / 100 · weight 50

passTools registered

4 / 4

10 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 352.60000000009313ms of navigation.

toolget_account

passCanonical entry point

4 / 4

All 10 tools register on the canonical document.modelContext entry point.

passSchema validity

5 / 5

All 10 tools declare a structurally valid object input schema.

warningSchema quality

3.2 / 4

2 of 10 tool schemas are harder for an agent to use than they need to be: list_models declares no required list, so an agent cannot tell which parameters are mandatory.

toollist_models

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

fix

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

passStub detection

5 / 5

All 10 tools declare an execute handler.

failAnnotations present

0 / 4

10 of 10 tools declare no readOnlyHint, so an agent cannot tell a read from a write without guessing from the name.

toolscan_images_c2pa

scan_images_c2pa, inspect_image_c2pa, list_models, estimate_credit_cost, search_articles

fix

{
  name: "scan_images_c2pa",
  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

10 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"));

warningInjection surface

0 / 3

3 of 10 tool contracts expose an injection or unsafe-argument surface: inspect_image_c2pa CSS selector or URL fetches third-party content.

toolinspect_image_c2pa

inspect_image_c2pa: CSS selector or URL fetches third-party content; get_article: Fetches third-party content by slug; generate_video: image_url fetches third-party content

fix

{
  name: "inspect_image_c2pa",
  execute: async (args) => {
    // Validate/sanitize args before acting on them.
    if (!isValid(args)) throw new Error("invalid arguments");
    /* ... */
  }
}

warningNaming quality

1.8 / 2

Tool naming makes selection harder than it needs to be: 2 names do not start with a verb (scan_images_c2pa).

toolscan_images_c2pa

fix

{ name: "scan_images_c2pa" /* short, unique, verb-based */ }

passDescription quality

6 / 6

All 10 rated tool descriptions say what the tool does, when to use it, and what it returns.

failTool selection

4.7 / 14

An agent completed 1 of 3 canonical intents against this tool set; on "List the transactions from the last month." no tool on the page served it.

failCoverage vs. site type

2.7 / 8

The tool set covers 1 of the 3 things an agent needs on a finance site; it cannot list transactions or activity or move money or place an order.

12 / 12

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