## 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 2026-08-03.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - 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**: 63/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1001 tokens (~250/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **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.

### 2026-08-03 (score 62, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-01 (score 61, +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.

### 2026-07-31 (score 60, +2)

## MCP tools (4)

### `get_access_pattern` (~259 tokens)

Get data access snippet

Get the storage URI and working code for opening a dynamical.org
dataset's data.

dynamical.org publishes a Python package, `dynamical-catalog`, that
reads the STAC catalog itself to resolve and open a dataset -- it's the
recommended access pattern because it can't go stale even if the
underlying storage format or location changes. This tool also returns
the dataset's low-level storage details (from the STAC asset, fetched
live) and a lower-level xarray/fsspec snippet for callers who need
direct access instead of the wrapper package.

Args:
    collection_id: A STAC collection id, e.g. "noaa-gfs-forecast". Use
        search_catalog to discover ids.

Returns:
    A dict with the recommended `dynamical_catalog.open(...)` snippet,
    a `worked_example` pulled from the collection's own STAC metadata
    when one is published, the raw asset URI/type/storage options, and
    a generated low-level open snippet (icechunk/zarr/geoparquet,
    chosen from the asset's declared type). Raises ValueError (listing
    valid ids) if collection_id is unknown.

Input parameters:

- `collection_id` (string, required)

### `get_dataset_info` (~210 tokens)

Get dataset details

Get documentation, spatial/time resolution, domain, and update cadence
for one dynamical.org dataset.

dynamical.org/catalog is itself rendered from this same STAC catalog, so
this tool fetches the collection document live (short TTL cache) rather
than relying on anything baked into this server -- it's always as fresh
as the STAC catalog itself.

Args:
    collection_id: A STAC collection id, e.g. "noaa-gfs-forecast",
        "noaa-hrrr-analysis", or "ecmwf-aifs-ens-forecast". Use
        search_catalog to discover ids.

Returns:
    A dict with title/model name, prose descriptions, spatial and time
    domain/resolution, forecast range (for forecast datasets), license
    and attribution, the dataset's variables, and links to its docs
    page and example notebooks. Raises ValueError (listing valid ids)
    if collection_id is unknown.

Input parameters:

- `collection_id` (string, required)

### `list_recent_runs` (~227 tokens)

List recent forecast runs

Check run freshness and arrival status for a dynamical.org forecast
dataset, from the same public feed status.dynamical.org's dashboard polls.

Only forecast collections are pipeline-monitored today (analysis
collections like noaa-gfs-analysis or noaa-mrms-conus-analysis-hourly
aren't yet tracked by this feed).

Args:
    collection_id: A STAC collection id, e.g. "noaa-gfs-forecast".
    limit: Maximum number of recent runs to return, most recent first
        (default 10).

Returns:
    A dict with the overall pipeline `sla_status`, this product's
    cadence and next expected init/completion time, typical latency
    stats, and up to `limit` recent runs (`init_time`, `status`,
    `completion_pct`, `on_timedness`, arrival/latency timestamps). If
    collection_id isn't pipeline-monitored, returns `monitored`: False
    plus the list of collection ids that are.

Input parameters:

- `collection_id` (string, required)
- `limit` (integer)

### `search_catalog` (~239 tokens)

Search weather & climate catalog

Search dynamical.org's STAC catalog of cloud-optimized weather and
climate datasets.

Matches against each dataset's model name, description, spatial/time
domain and resolution, forecast range, and variable names -- so a query
can be a model ("GFS"), a variable ("precipitation", "temperature_2m"),
a region ("continental US", "global"), or a resolution ("3km", "0.25
degree"). Results are ranked by number of matching terms.

Args:
    query: Free-text search terms, e.g. "hourly precipitation CONUS"
        or "ECMWF ensemble forecast".
    limit: Maximum number of results to return (default 5).

Returns:
    {"query": ..., "results": [{"collection_id", "title", "model_name",
    "description_summary", "spatial_domain", "spatial_resolution",
    "matched_variables", "score"}, ...]}, most relevant first. Pass a
    result's collection_id to get_dataset_info, get_access_pattern, or
    list_recent_runs.

Input parameters:

- `limit` (integer)
- `query` (string, required)
