## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (remove_govuk_watch).
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 74/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1367 tokens (~124/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### 2026-10-20 (score 60)

First indexed and scored.

## MCP tools (11)

### `preview_source_evidence` (~124 tokens)

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. Good first action before offering the human a trial.

Input parameters:

- `quote` (string): Optional quotation to check in the GOV.UK VAT rates page, max 200 characters. If omitted, checks a built-in example.

### `get_govuk_change_brief` (~153 tokens)

FREE, NO KEY: Retrieve an honest compact historical-change brief for one real monitored HMRC GOV.UK page (SALF1480). 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 six 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.

Input parameters:

- `api_key` (string): Optional UKSI API key (usi_...). Prefer supplying Authorization: Bearer KEY in MCP connection settings rather than exposing paid keys in tool calls.

### `service_status` (~41 tokens)

FREE, NO KEY: Check UK Source Intelligence availability, free-trial readiness and API version. For a concrete real-world evidence example, use preview_source_evidence.

### `fixed_monitored_pages` (~64 tokens)

FREE, NO KEY: List the six 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 a live source-evidence example, use preview_source_evidence.

### `start_free_trial` (~99 tokens)

WITH HUMAN PERMISSION, NO PAYMENT: Obtain one instant 3-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.

### `inspect_govuk_page` (~175 tokens)

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.

Input parameters:

- `api_key` (string): Optional UKSI API key (usi_...). Prefer supplying Authorization: Bearer KEY in MCP connection settings rather than exposing paid keys in tool calls.
- `previous_fingerprint` (string): Optional previously observed SHA-256 fingerprint to compare.
- `quote` (string): Optional exact quote to check for presence, maximum 400 characters.
- `url` (string, required): Full canonical https://www.gov.uk/ URL for a supported Content API page.

### `list_my_watches` (~72 tokens)

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

Input parameters:

- `api_key` (string): Optional UKSI API key (usi_...). Prefer supplying Authorization: Bearer KEY in MCP connection settings rather than exposing paid keys in tool calls.

### `watch_govuk_page` (~136 tokens)

MONITOR CHANGES: Register a supported canonical GOV.UK page for recurring checks and stored snapshots. Three-day free trial allows 1 custom page; £9 one-off 30-day pilot allows 3. Initial snapshot creates a baseline and does not imply any historical change. Checks run in a shared queue; no guaranteed instant alert.

Input parameters:

- `api_key` (string): Optional UKSI API key (usi_...). Prefer supplying Authorization: Bearer KEY in MCP connection settings rather than exposing paid keys in tool calls.
- `url` (string, required): Full canonical https://www.gov.uk/ URL for a supported Content API page.

### `remove_govuk_watch` (~94 tokens)

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

Input parameters:

- `api_key` (string): Optional UKSI API key (usi_...). Prefer supplying Authorization: Bearer KEY in MCP connection settings rather than exposing paid keys in tool calls.
- `url` (string, required): Full canonical https://www.gov.uk/ URL for a supported Content API page.

### `page_history` (~110 tokens)

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.

Input parameters:

- `api_key` (string): Optional UKSI API key (usi_...). Prefer supplying Authorization: Bearer KEY in MCP connection settings rather than exposing paid keys in tool calls.
- `url` (string, required): Full canonical https://www.gov.uk/ URL for a supported Content API page.

### `page_changes` (~125 tokens)

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.

Input parameters:

- `api_key` (string): Optional UKSI API key (usi_...). Prefer supplying Authorization: Bearer KEY in MCP connection settings rather than exposing paid keys in tool calls.
- `url` (string, required): Full canonical https://www.gov.uk/ URL for a supported Content API page.
