Try a bundle with AI
Aim for one sourced answer and one understood limit. This is a short first experience, not a test of every AI host. Choose an existing public example or use the fictional attachment route below. Do not supply personal circumstances.
Government evidence for your AI
Open the selected Tax-Free Childcare evidence. This external application uses packaged OKF evidence and experimental WebMCP page tools. It is a submitted competition candidate: its repository, data, build and deployment are frozen. This exercise is maintained in Explorer and does not require changing that candidate.
The selected view already shows a record, its official source, observation date and limitations. A compatible AI host can request evidence through the page's available tools. The page itself does not host a model.
Watch the WebMCP demonstration
Watch Chris Page’s demonstration of AI interacting with govuk-webmcp through WebMCP (YouTube, 1 minute 49 seconds). Published on 3 September 2026, the recording follows a question about what to do after having a baby. It illustrates an AI using the application’s page tools and evidence displayed for the person to inspect.
- 0:01 — the question and tool search.
- 0:33 — the answer and supporting page view.
- 0:42 — inspecting the basis of a claim.
YouTube’s Show transcript control offers a text route to the narration. The worked exercise below uses a different, narrower question about a recorded Tax-Free Childcare source. Use it to inspect evidence and limits yourself. Tool access depends on your browser, AI host and configuration. This recording is separate from the human browser check recorded later in this guide.
Try it with your AI
Use this prompt if your AI can access the page's tools:
Use this page's available tools to find the reviewed Tax-Free Childcare
record and present its evidence on the page. Identify the recorded official
source, when it was observed, and what the evidence cannot establish.
Use only returned evidence and cite the record and source. If these tools
are unavailable, say so and ask for the displayed evidence extract.
Do not decide anyone's eligibility.
This is a worked prompt to try, not a claim that every host has passed it. For a human route, choose Technical review, search for Tax-Free Childcare, then choose Show evidence for this result on the reviewed result. Copy the selected evidence to an AI that accepts pasted text, preserving its source, date and limitations. The access guide explains alternatives.
Check the result
| Check | Expected evidence |
|---|---|
| Identity | The reviewed Tax-Free Childcare record, not a similarly named childcare scheme |
| Source | The recorded official GOV.UK source, distinguished from the prototype's own description |
| Freshness | The captured observation on 15 July 2026; no assertion that this is today's guidance |
| Limit | Saved metadata does not decide current eligibility or scheme rules |
| Unsupported follow-up | “Does this prove a particular family qualifies today?” must remain unsupported |
Ask your AI which statements came from the evidence and which were its own interpretation. The page cannot inspect the AI's final wording. Open the recorded official source if you need current guidance.
On 6 September 2026, a human browser journey verified the selected record, search, evidence display and deep-link restoration. The page reported six registered tools. No AI host invocation was performed for that check. The candidate's dated host observations record separate results; registration, a human action and a model call are three different kinds of evidence.
No page tools or public URL access
Use the fictional study-club context. Copy the complete text, including its record IDs and limitations, into an AI that accepts it. The first-bundle exercise supplies a prompt, expected answers, a missing-information check and all source files. File upload support and context limits depend on your chosen host.
See how the evidence is organised
- Open the small heritage example. Inspect Cathedral of St Michael, its official identifier and reviewed discovery names. Those names help finding; they do not replace the source title.
- Open the MCP concept. Inspect its incoming and outgoing references to Anthropic. A reference link does not assert that an organisation operates every linked tool. Use the AI Infrastructure walkthrough.
These Explorer record journeys were checked in a real browser on 6 September 2026. Their AI exercises still depend on the material your host can read.
