No check matched anything in these tool definitions.


## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `get_access_pattern`

- The name "get_access_pattern" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.

```

### `get_dataset_info`

- The name "get_dataset_info" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.

```

### `list_recent_runs`

- The name "list_recent_runs" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.

```

### `search_catalog`

- The name "search_catalog" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.

```
