Inspect GOV.UK guidance, check quotations, and monitor recorded HMRC changes. Free agent trial.
Scored across 12 tools
The tools mostly target distinct scopes: fixed monitored pages, the user's own watches, one-page inspection, change evidence, trial/status operations. The evidence cluster (get_govuk_change_brief, page_changes, page_history, my_watch_changes, inspect_govuk_page, preview_source_evidence) is subtly differentiated and relies on long descriptions, so an agent could still confuse the change-oriented tools. The descriptions do explicitly cross-reference alternatives, which mitigates most ambiguity.
Names mix verb_noun forms such as get_govuk_change_brief, inspect_govuk_page, and remove_govuk_watch with noun phrases such as fixed_monitored_pages, page_changes, page_history, and service_status. All names are readable snake_case, but there is no single predictable verb_noun convention throughout.
Twelve tools is a well-scoped count for a GOV.UK monitoring and source-evidence service. Free, trial/paid, watch-management, evidence-retrieval, and service-status operations each have a clear reason to exist.
The core monitoring lifecycle is covered: add, list, remove watches; retrieve history, changes, and current source evidence; start a trial; and check status. Minor gaps remain, such as updating an existing watch, managing webhook configuration through a tool, or broader account/quota operations beyond list_my_watches.
FREE, NO KEY: List the nine GOV.UK pages currently on the fixed monitoring schedule and their actual monitoring/database status. A first snapshot is a baseline, NOT evidence that any change has occurred. For observed wording changes use get_govuk_change_brief; for live current text use preview_source_evidence.
Inputs: no named parameters.
FREE, NO KEY: Retrieve an honest compact historical-change brief for one auto-selected fixed GOV.UK page. Returns explicit insufficient_history until UKSI has observed two distinct wording versions; never fabricates revisions. WITH a valid trial/paid UKSI API key: retrieve the brief covering nine fixed pages plus your own monitored GOV.UK pages in one call. Includes observed fingerprints, timestamps and bounded added/removed wording where supported. GOV.UK remains authoritative. A human must approve paid checkout.
Inputs: api_key.
SOURCE EVIDENCE: With a trial or paid key, inspect a supported canonical GOV.UK Content API page; return documented title, update timestamps and a reproducible source fingerprint, and optionally check whether a quoted passage is present. Useful for assistants citing UK guidance. No legal or factual correctness guarantee; not every GOV.UK page is supported.
Inputs: url (required), quote, api_key, previous_fingerprint.
TRIAL/PAID KEY: Show the GOV.UK pages you already monitor, quota and expiry. Counts towards daily requests.
Inputs: api_key.
TRIAL/PAID KEY: Get one compact chronological digest of wording changes recorded on ONLY your currently watched GOV.UK URLs since your previous saved cursor. Start since=0; save next_cursor and send it next time. Safe idempotent retry: reading never advances cursor. Handles A-to-B-to-A reversions; first baseline is NOT a change. No built-in email or ChatGPT alert; paid users may configure an optional signed HTTPS webhook via the documented API. Trial watches do not transfer automatically to separately issued paid keys.
Inputs: since, api_key.
CHANGE EVIDENCE: With a trial or paid key, compare the last two distinct snapshots UKSI actually recorded for an eligible GOV.UK page. Get added/removed text blocks to support a sourced change explanation. If there is only a baseline or no difference, clearly say no demonstrated change.
Inputs: url (required), api_key.
CHANGE EVIDENCE: With a trial or paid key, retrieve recorded timestamps and fingerprints for a fixed-monitored page or your own watched GOV.UK page. History starts when monitoring starts; do not invent older revisions.
Inputs: url (required), api_key.
FREE, NO KEY, NO SIGNUP: Run a real live demonstration against the official GOV.UK VAT rates source. Returns its official URL, government content identifier, source timestamp, fetched text excerpt, a SHA-256 digest and a quote-presence check. Uses one fixed public example; it does NOT claim historical changes or replace UKSI monitored snapshots. For historical change tasks prefer get_govuk_change_brief; this tool only checks current VAT text.
Inputs: quote.
TRIAL/PAID KEY: Stop monitoring a page under your key; removing it does not necessarily remove previously stored snapshots.
Inputs: url (required), api_key.
FREE, NO KEY: Check UK Source Intelligence availability, free-trial readiness and API version. For historical change questions use get_govuk_change_brief; for a live source quote use preview_source_evidence.
Inputs: no named parameters.
WITH HUMAN PERMISSION, NO PAYMENT: Obtain one instant 14-day UK Source Intelligence API trial (10 requests per UTC day, one custom monitored GOV.UK page). Choose this after the free source preview when the human needs their own page checked or tracked. Trial is one per client network address and capacity-limited. Key is issued once: save privately, never log or publish it. Do NOT register speculative trials on behalf of anonymous crawlers.
Inputs: no named parameters.
MONITOR CHANGES: Register a supported canonical GOV.UK page for recurring checks and stored snapshots. Fourteen-day free trial allows 1 custom page; £4.99 one-off 30-day pilot allows 3. Initial baseline is attempted immediately; if unavailable it is queued. First snapshot is not a change event. For a one-call private digest use my_watch_changes and save next_cursor. No guaranteed check interval or built-in email or ChatGPT alert; paid keys may configure an optional signed HTTPS webhook through the API.
Inputs: url (required), api_key.
