## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-uk-ons).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 6 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 78/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 567 tokens (~94/item across 6 items; 6 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 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.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-29 (score 81)

First indexed and scored.

## MCP tools (6)

### `list_datasets` (~64 tokens)

Paginated catalog of ONS datasets. Returns id, title, description, contacts, release frequency, last release, theme.

Input parameters:

- `limit` (number): 1-100 (default 20)
- `offset` (number): 0-based offset (default 0)

### `get_dataset` (~55 tokens)

Single dataset metadata: title, description, methodology, contacts, release frequency, latest version, related links.

Input parameters:

- `dataset_id` (string, required): ONS dataset ID (e.g., "cpih01", "ashe-table-1")

### `list_editions` (~67 tokens)

List all named editions of an ONS dataset (e.g., "time-series", "annual"). Returns each edition label, release date, state, and the latest version ID to use with get_version or get_observations.

Input parameters:

- `dataset_id` (string, required): ONS dataset ID

### `get_version` (~81 tokens)

Fetch metadata for a specific version of an ONS dataset edition, including dimension definitions with codelist links, CSV/XLS download URLs, release date, and publication state.

Input parameters:

- `dataset_id` (string, required): ONS dataset ID
- `edition` (string, required): Edition label
- `version` (string, required): Version (e.g., "1", "2")

### `get_observations` (~121 tokens)

Fetch observations from a dataset/edition/version. Pass dimension filters as `dimensions` map ({"geography": "K02000001", "time": "2023"}). Use `*` for "all values" within a dimension.

Input parameters:

- `dataset_id` (string, required): ONS dataset ID
- `dimensions` (object, required): Dimension code → value (or "*" for all). Example: {"geography":"K02000001","time":"2023"}.
- `edition` (string, required): Edition label
- `version` (string, required): Version

### `ons_timeseries` (~126 tokens)

Fetch a single UK ONS time series by its www.ons.gov.uk URI (the classic timeseries API, distinct from the filterable datasets above). Returns the full series JSON (description + observations). e.g. uri "/economy/grossdomesticproductgdp/timeseries/abmi/pn2". (Named ons_timeseries — get_series is used by many other economic-data packs.)

Input parameters:

- `uri` (string, required): ONS timeseries URI, e.g. "/economy/grossdomesticproductgdp/timeseries/abmi/pn2".
