## 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 2026-08-20.

- **Endpoint Security**: 63/100
  - 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 (delete_monitor).
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 73/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1298 tokens (~118/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**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 89/100
  - 91% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 85% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

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.

### 2026-08-19 (score 67, +1)

No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-17 (score 66, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (11)

### `list_sources` (~48 tokens)

List data sources

List the official statistical sources served by this data layer (e.g. Statistics Canada, FRED), with dataset/series counts, cadence notes, and terms links. Start here to see what exists.

### `search_catalog` (~198 tokens)

Search the series catalog

Find series across ALL sources in one call: case-insensitive search over series ids, indicator names, geographies, and dataset titles (e.g. "unemployment canada", "10-year treasury", "CPI"). Returns candidate series with units, coverage, verification status, and license, plus datasetMatches from the wider dataset index — datasets whose series can be requested by source-native id and are fetched from the official source on first call. The fastest path from a question to the exact series id to fetch or pin in the answer tool.

Input parameters:

- `limit` (integer): Max results (default 20)
- `offset` (integer): Skip the first N ranked hits (default 0). When hasMore is true, call again with offset = offset + limit.
- `query` (string, required): Search terms, e.g. "unemployment rate canada"
- `source` (string): Optional source slug to restrict to, e.g. 'fred'

### `list_datasets` (~54 tokens)

List datasets in a source

List the datasets (official releases/tables) available in one source, with coverage dates and links to the official table pages.

Input parameters:

- `source` (string, required): Source slug, e.g. 'fred' or 'statcan'

### `get_series` (~100 tokens)

Get series metadata + verification

Full metadata for one series: indicator, unit, frequency, geography, coverage, its VERIFICATION STATUS (passing/stale/failing/unverified from golden-value + freshness checks against the live source), recent check records, and the citation to the official table.

Input parameters:

- `seriesId` (string, required): Source-native series id, e.g. 'UNRATE' or 'v41690973'
- `source` (string, required): Source slug, e.g. 'fred'

### `get_observations` (~132 tokens)

Get observations (with provenance)

Observation values for one series. Every value carries provenance (the exact source URL it came from, retrieval time, connector version) and the envelope carries the series verification status + citation. Defaults to the latest 60 points; use start/end (YYYY-MM-DD) or latest to control the window.

Input parameters:

- `end` (string): YYYY-MM-DD inclusive upper bound
- `latest` (integer): Return only the latest N points (default 60 when no start/end given)
- `seriesId` (string, required)
- `source` (string, required)
- `start` (string): YYYY-MM-DD inclusive lower bound

### `get_series_stats` (~99 tokens)

Summary statistics for a series

Latest value, previous, all-time min/max, mean, and change vs the previous period and vs a year ago — computed over the verified store, with the citation attached. The cheap way to answer "what is it now and how has it moved" without a full analysis run.

Input parameters:

- `seriesId` (string, required): Series id, e.g. 'DGS10'
- `source` (string, required): Source slug, e.g. 'fred'

### `create_monitor` (~123 tokens)

Watch a series (webhook on movement)

Create a monitor: when the store's refresh lands a new period or a revised value for the series, a series.updated webhook fires to your URL with the new value, verification status, and citation. Requires an API key (free with an account at /account); webhook must be https. Manage with list_monitors / delete_monitor.

Input parameters:

- `seriesId` (string, required): Series id, e.g. 'DGS10'
- `source` (string, required): Source slug, e.g. 'fred'
- `webhookUrl` (string, required): https URL to receive series.updated events

### `list_monitors` (~27 tokens)

List your monitors

Monitors on your API key, with delivery health (last fired, failures, active).

### `delete_monitor` (~18 tokens)

Delete one of your monitors

Input parameters:

- `id` (string, required): Monitor id from list_monitors

### `answer` (~252 tokens)

Answer a question from verified data

The flagship: ask a natural-language question about the served official statistics. Returns a COMPUTED answer (real Python runs in a sandbox over the verified store, nothing is estimated by a model), the Plotly chart, the Python code, citations to the official tables, and a verification badge per series. CROSS-SOURCE: one question may join series from DIFFERENT agencies, e.g. unemployment from the US BLS, Statistics Canada and the UK ONS in a single call, for correlations, ratios, and like-for-like comparison. How many series one question may join is set by the caller's plan; asking for more returns a series_limit error naming that cap. Returns a refusal when no served series can answer. Takes 10-40 seconds. Requires a free API key (create at /account on the Starwell host; pass Authorization: Bearer dlk_... or set STARWELL_API_KEY on the starwell-mcp bridge). Keyless calls return key_required.

Input parameters:

- `end` (string): YYYY-MM-DD
- `question` (string, required)
- `series` (array): Optional: pin exact series, across sources, and skip AI resolution
- `start` (string): YYYY-MM-DD

### `deep_analysis` (~247 tokens)

Deep multi-angle analysis from verified data

The moat: a PLANNED multi-section report on a question. The engine designs 3-4 orthogonal analyses (trend, statistics, outliers, cross-series relationships), runs real Python for each in the sandbox over the verified store, and synthesizes one decision-ready report. Every number computed, every series cited and verification-badged. Sections can join series from DIFFERENT agencies in one report, up to the caller's plan width; over it, the call returns a series_limit error naming that cap. Slower than answer (60-180 seconds), so use it for "analyze", "break down", "give me a full picture" asks; use the answer tool for a single direct question. Requires a free API key (create at /account on the Starwell host; pass Authorization: Bearer dlk_... or set STARWELL_API_KEY on the starwell-mcp bridge). Keyless calls return key_required.

Input parameters:

- `end` (string): YYYY-MM-DD
- `question` (string, required)
- `series` (array): Optional: pin exact series, across sources, and skip AI resolution
- `start` (string): YYYY-MM-DD
