Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 58 ms.

    protocolVersion 2025-11-25, serverInfo.name uk-source-intelligence-mcp.

  • Pass
    Lists tools

    tools/list returned 12 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 58 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 58 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    17 of 17 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-10-20T16:33:22.142235Z, within 180 days.

Capabilities

Tools 12

fixed_monitored_pages

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.

Discovered
get_govuk_change_brief

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.

Discovered
inspect_govuk_page

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.

Discovered
list_my_watches

TRIAL/PAID KEY: Show the GOV.UK pages you already monitor, quota and expiry. Counts towards daily requests.

Discovered
my_watch_changes

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.

Discovered
page_changes

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.

Discovered
page_history

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.

Discovered
preview_source_evidence

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.

Discovered
remove_govuk_watch

TRIAL/PAID KEY: Stop monitoring a page under your key; removing it does not necessarily remove previously stored snapshots.

Discovered
service_status

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.

Discovered
start_free_trial

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.

Discovered
watch_govuk_page

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.
