last good check
of 30 tools
The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
get_portal_metrics open 16m ago
Return a GDEX portal-wide metric. Args: metric: One of: volume_downloaded, unique_users, total_datasets, total_citations, gdex_volume, total_requests, top_datasets, ai_datasets
{ "type": "object", "title": "get_portal_metricsArguments", "properties": { "metric": { "type": "string", "title": "Metric", "default": "top_datasets" } } }arguments 11 linesget_staff open 16m ago
Return GDEX staff contacts, optionally filtered to a specific dataset. Args: dsid: Optional dataset ID. If omitted, returns all staff.
{ "type": "object", "title": "get_staffArguments", "properties": { "dsid": { "type": "string", "title": "Dsid", "default": "" } } }arguments 11 lineslist_request_statuses open 16m ago
List all subsetting request statuses for the authenticated user. Requires GDEX_TOKEN.
{ "type": "object", "title": "list_request_statusesArguments", "properties": {} }arguments 5 lineslist_datasets unknown never probed
List datasets available on GDEX, with their IDs and titles. The full catalog has ~1700 datasets — far too many to return at once. Always pass `query` to filter by keyword unless the user specifically wants to browse the whole catalog page by page. Args: query: Keyword(s) to filter by, matched case-insensitively as a substring against dataset id and title. Leave empty to browse unfiltered. limit: Max number of datasets to return (default 50, capped at 500) offset: Number of matching datasets to skip, for paging through results
{ "type": "object", "title": "list_datasetsArguments", "properties": { "limit": { "type": "integer", "title": "Limit", "default": 50 }, "query": { "type": "string", "title": "Query", "default": "" }, "offset": { "type": "integer", "title": "Offset", "default": 0 } } }arguments 21 linesget_dataset_field unknown never probed
Return one metadata field for a dataset. Prefer describe_dataset when the user wants a general summary covering several of these at once (abstract, temporal, spatial_coverage, variables, data_formats, volume) — this tool is for pulling a single field, including the fields describe_dataset doesn't cover (publications, contributors, related_datasets, documentation). Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 field: One of: abstract, variables, temporal, spatial_coverage, publications, contributors, data_formats, volume, related_datasets, documentation
{ "type": "object", "title": "get_dataset_fieldArguments", "required": [ "dsid", "field" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "field": { "type": "string", "title": "Field" } } }arguments 18 linesdescribe_dataset unknown never probed
Return a combined overview of a dataset — abstract, temporal coverage, spatial coverage, variables, data formats, and volume — in a single call. Prefer this over calling get_dataset_field repeatedly when the user wants a general summary of a dataset. If one of the underlying fields fails to load, it's returned as {"error": ...} rather than failing the whole call. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002
{ "type": "object", "title": "describe_datasetArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" } } }arguments 13 linesget_file_groups unknown never probed
Return file groups for a dataset. Pass gindex to get child groups under a parent. Groups nest (dataset -> format -> year -> month, or similar, varying by dataset) and there's no way to predict a child's gindex in advance — each group's gindex/url is dataset-specific and only knowable from the parent response. To drill down, read the gindex (or url) off a row in this response and pass that as the next call's gindex. This never returns file rows, only groups — every response stays small regardless of how many files the dataset holds, unlike get_dataset_files. Descend until a call returns empty ({} or []): that means the gindex you just called with is a leaf with no further subgroups, so it's safe to call get_dataset_files there for the actual files. find_dataset_files automates exactly this walk if you'd rather not do it by hand. At the top level, watch for a "Kerchunk Reference Files" (or similar ARCO-related) group alongside the raw-format groups. For an analysis task, prefer pulling from there (see also has_arco/get_arco_variables) over a raw data file when one's available — it avoids downloading a whole file just to read a subset of it. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 gindex: Optional group index to fetch child groups
{ "type": "object", "title": "get_file_groupsArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "gindex": { "type": "string", "title": "Gindex", "default": "" } } }arguments 18 linesget_dataset_files unknown never probed
Return a paginated file listing for a dataset or a specific group. Depending on how deep gindex is in the group hierarchy, this returns either actual file rows or another layer of subgroup summaries — there's no way to tell in advance which you'll get. If you get subgroups, read the gindex (or url) off a row and call again with that gindex to go one level deeper; gindex values are dataset-specific and can't be guessed. A shallow gindex on a large dataset can return a very large response (thousands of files) — the file-row portion of the response is capped at 500 rows (look for "_truncated": true). Two ways to avoid hitting that cap instead of drilling down group by group: pass filter_wfile with a filename pattern (e.g. a date like "20220808") to filter down to matching files, or page through a known group's results with `page`. filter_wfile only filters actual file rows, so it has no effect at a gindex that's still returning a subgroup summary rather than files — if a first attempt comes back unfiltered, descend one level (see get_file_groups) and retry there. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 gindex: Optional group index to filter files page: Page number to fetch (for a group with more files than fit on one page) filter_wfile: Filter files by name pattern, e.g. "20220808" to match a date fl: File list source (defaults to "web" server-side)
{ "type": "object", "title": "get_dataset_filesArguments", "required": [ "dsid" ], "properties": { "fl": { "type": "string", "title": "Fl", "default": "" }, "dsid": { "type": "string", "title": "Dsid" }, "page": { "type": "integer", "title": "Page", "default": 0 }, "gindex": { "type": "string", "title": "Gindex", "default": "" }, "filter_wfile": { "type": "string", "title": "Filter Wfile", "default": "" } } }arguments 33 linesfind_dataset_files unknown never probed
Search a dataset's file-group hierarchy for files matching a name pattern (e.g. a date like "20220808"), without ever pulling a large, context-blowing file listing. Automates the pattern described in get_file_groups: recursively calls get_file_groups, descending into every child gindex, until a gindex returns no further children (a leaf group) — then calls get_dataset_files there with filter_wfile=name_pattern and keeps only the matches. Prefer this over manually drilling with get_file_groups/get_dataset_files when you don't already know roughly where in the hierarchy to look. A dataset's hierarchy can be large (hundreds of leaf groups), and this tool has no way to know in advance which branches might contain a match, so it may need to visit many groups to be thorough. Pass start_gindex if you already know a good starting point (e.g. from a prior get_file_groups call, or a related dataset's structure) to narrow and speed up the search. If the number of groups visited hits max_groups_visited, the search stops early and `stopped_early` comes back true — narrow with start_gindex and retry, or raise the cap. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 name_pattern: Filename substring/pattern to match, e.g. "20220808" for a date start_gindex: Optional group index to start the search from, instead of the dataset root max_groups_visited: Safety cap on groups traversed before giving up (default 300)
{ "type": "object", "title": "find_dataset_filesArguments", "required": [ "dsid", "name_pattern" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "name_pattern": { "type": "string", "title": "Name Pattern" }, "start_gindex": { "type": "string", "title": "Start Gindex", "default": "" }, "max_groups_visited": { "type": "integer", "title": "Max Groups Visited", "default": 300 } } }arguments 28 linesget_filesearch_datatypes unknown never probed
Return the file-search datatypes available for a dataset (a subset of "grid", "cyclone_fix", "sensor"). Call this before the other filesearch_* tools to know which one(s) apply — a dataset only supports search for the datatypes it actually contains. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002
{ "type": "object", "title": "get_filesearch_datatypesArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" } } }arguments 13 linesget_filesearch_grid_filters unknown never probed
Return the valid parameter/product/grid/level codes and date range for "grid" datatype file search on a dataset. Use this to discover the codes to pass to get_filesearch_grid_files, optionally narrowed by any filters you already know you want. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 valid_datetime_min: Restrict to data valid on/after "YYYY-MM-DD HH:MM" valid_datetime_max: Restrict to data valid on/before "YYYY-MM-DD HH:MM" parameters: Restrict to specified parameter code(s) products: Restrict to specified product code(s) grids: Restrict to specified grid code(s) levels: Restrict to specified vertical level code(s)
{ "type": "object", "title": "get_filesearch_grid_filtersArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "grids": { "type": "array", "items": { "type": "string" }, "title": "Grids", "default": [] }, "levels": { "type": "array", "items": { "type": "string" }, "title": "Levels", "default": [] }, "products": { "type": "array", "items": { "type": "string" }, "title": "Products", "default": [] }, "parameters": { "type": "array", "items": { "type": "string" }, "title": "Parameters", "default": [] }, "valid_datetime_max": { "type": "string", "title": "Valid Datetime Max", "default": "" }, "valid_datetime_min": { "type": "string", "title": "Valid Datetime Min", "default": "" } } }arguments 55 linesget_filesearch_cyclone_fix_filters unknown never probed
Return the valid date range and other filters for "cyclone_fix" datatype file search on a dataset. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 valid_datetime_min: Restrict to data valid on/after "YYYY-MM-DD HH:MM" valid_datetime_max: Restrict to data valid on/before "YYYY-MM-DD HH:MM"
{ "type": "object", "title": "get_filesearch_cyclone_fix_filtersArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "valid_datetime_max": { "type": "string", "title": "Valid Datetime Max", "default": "" }, "valid_datetime_min": { "type": "string", "title": "Valid Datetime Min", "default": "" } } }arguments 23 linesget_filesearch_sensor_filters unknown never probed
Return the valid date range and other filters for "sensor" datatype file search on a dataset. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 valid_date_min: Restrict to data valid on/after "YYYY-MM-DD" valid_date_max: Restrict to data valid on/before "YYYY-MM-DD"
{ "type": "object", "title": "get_filesearch_sensor_filtersArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "valid_date_max": { "type": "string", "title": "Valid Date Max", "default": "" }, "valid_date_min": { "type": "string", "title": "Valid Date Min", "default": "" } } }arguments 23 linesget_filesearch_cyclone_fix_files unknown never probed
Search for data files containing "cyclone_fix" datatype data, optionally filtered by time range. Results are paginated; use get_filesearch_result_page with the returned result_id to fetch additional pages. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 valid_datetime_min: Restrict to data valid on/after "YYYY-MM-DD HH:MM" valid_datetime_max: Restrict to data valid on/before "YYYY-MM-DD HH:MM"
{ "type": "object", "title": "get_filesearch_cyclone_fix_filesArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "valid_datetime_max": { "type": "string", "title": "Valid Datetime Max", "default": "" }, "valid_datetime_min": { "type": "string", "title": "Valid Datetime Min", "default": "" } } }arguments 23 linesget_filesearch_sensor_files unknown never probed
Search for data files containing "sensor" datatype data, optionally filtered by date range. Results are paginated; use get_filesearch_result_page with the returned result_id to fetch additional pages. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 valid_date_min: Restrict to data valid on/after "YYYY-MM-DD" valid_date_max: Restrict to data valid on/before "YYYY-MM-DD"
{ "type": "object", "title": "get_filesearch_sensor_filesArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "valid_date_max": { "type": "string", "title": "Valid Date Max", "default": "" }, "valid_date_min": { "type": "string", "title": "Valid Date Min", "default": "" } } }arguments 23 linesget_filesearch_result_page unknown never probed
Return a page of results from a previous get_filesearch_*_files call, by its result_id. Use this to page through file-search results beyond the first page (see the "pagination" block of a files/results response for num_pages and next_page). Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 result_id: The result_id from a previous filesearch files/results response page_num: Page number to retrieve
{ "type": "object", "title": "get_filesearch_result_pageArguments", "required": [ "dsid", "result_id", "page_num" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "page_num": { "type": "integer", "title": "Page Num" }, "result_id": { "type": "string", "title": "Result Id" } } }arguments 23 linesget_data_access unknown never probed
Return data access options for a dataset — download links, Globus URLs, access methods. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002
{ "type": "object", "title": "get_data_accessArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" } } }arguments 13 lineshas_arco unknown never probed
Check whether Analysis-Ready Cloud-Optimized (ARCO) data is available for a dataset. For analysis tasks, call this (and check for a "Kerchunk Reference Files" group via get_file_groups) before reaching for raw data files — reading through ARCO/kerchunk references avoids downloading whole files just to subset them. When picking among kerchunk reference variants, always use the one with "-osdf" in its name (see get_arco_variables) — other variants' chunk targets can be internal paths that only resolve on NCAR's network. Open it with xr.open_dataset(url, engine="kerchunk", storage_options={"remote_protocol": "https", "lazy": True}) rather than hand-building an fsspec reference filesystem. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002
{ "type": "object", "title": "has_arcoArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" } } }arguments 13 linesget_arco_variables unknown never probed
Return the list of ARCO variables available for a dataset. Each row's type (index 2) is either "zarr" or "reference" (kerchunk). A "reference" variable is often listed multiple times, once per kerchunk reference variant (plain, "-remote-https", "-remote-osdf", etc.) — always pick the "-osdf" variant's URL; the others' chunk targets can be internal paths that only resolve on NCAR's network. Open it with xr.open_dataset(url, engine="kerchunk", storage_options={"remote_protocol": "https", "lazy": True}) — that's better behaved than hand-building an fsspec reference filesystem. A "zarr" row needs no variant picking — its URL already routes through the OSDF director (rewritten automatically); open it directly with xr.open_dataset(url, engine="zarr"). Results are capped at 300 rows (look for "truncated": true); narrow with search_arco_variables if you hit the cap. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002
{ "type": "object", "title": "get_arco_variablesArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" } } }arguments 13 linessearch_arco_variables unknown never probed
Search ARCO variables by name for a dataset. As with get_arco_variables, a "reference" (kerchunk) match is often listed once per variant — always pick the "-osdf" variant's URL (reachable from anywhere), and open it with xr.open_dataset(url, engine="kerchunk", storage_options={"remote_protocol": "https", "lazy": True}). A "zarr" match needs no variant picking — its URL already routes through the OSDF director (rewritten automatically); open it directly with xr.open_dataset(url, engine="zarr"). Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 query: Search text to match against variable names
{ "type": "object", "title": "search_arco_variablesArguments", "required": [ "dsid", "query" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "query": { "type": "string", "title": "Query" } } }arguments 18 linesget_dataset_metrics unknown never probed
Return a per-dataset metric. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 metric: One of: users_month, users_year, volume_month, volume_year
{ "type": "object", "title": "get_dataset_metricsArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "metric": { "type": "string", "title": "Metric", "default": "volume_year" } } }arguments 18 linescheck_request_status unknown never probed
Check the status of a specific subsetting request. Requires GDEX_TOKEN. Args: rindex: Request index/ID
{ "type": "object", "title": "check_request_statusArguments", "required": [ "rindex" ], "properties": { "rindex": { "type": "string", "title": "Rindex" } } }arguments 13 linesget_request_files unknown never probed
Return the output files for a completed subsetting request. Requires GDEX_TOKEN. Args: rindex: Request index/ID
{ "type": "object", "title": "get_request_filesArguments", "required": [ "rindex" ], "properties": { "rindex": { "type": "string", "title": "Rindex" } } }arguments 13 linesget_control_file_template unknown never probed
Return the control file template for building a subsetting request for a dataset. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002
{ "type": "object", "title": "get_control_file_templateArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" } } }arguments 13 linesvalidate_subset_request unknown never probed
Check a subset request body against the dataset's control file template, without submitting anything. Use this before submit_subset_request to catch missing or unrecognized fields fast, instead of finding out from a failed API call. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 request_json: JSON string of the subsetting request body to validate
{ "type": "object", "title": "validate_subset_requestArguments", "required": [ "dsid", "request_json" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "request_json": { "type": "string", "title": "Request Json" } } }arguments 18 linessubmit_subset_request unknown never probed
Submit a data subset request to GDEX. Requires GDEX_TOKEN. Args: request_json: JSON string of the subsetting request body. Use get_control_file_template to get the expected structure for a dataset, or validate_subset_request to check it before submitting.
{ "type": "object", "title": "submit_subset_requestArguments", "required": [ "request_json" ], "properties": { "request_json": { "type": "string", "title": "Request Json" } } }arguments 13 linessubmit_and_wait_for_request unknown never probed
Submit a subset request and poll its status until it finishes, fails, or timeout_s elapses — instead of calling submit_subset_request and then manually looping on check_request_status. Requires GDEX_TOKEN. GDEX's API schema doesn't document the exact status vocabulary, so "finished" is a best-effort match on the status text (words like "complete" vs. "error"/"fail"). If the outcome comes back "timeout", that means the request is still pending by our reading, not that it failed — keep polling with check_request_status(rindex), or re-run this tool with a longer timeout_s. If it comes back "unknown", the status payload didn't contain a field we recognize; inspect the raw "status" value yourself. Args: request_json: JSON string of the subsetting request body (see get_control_file_template). poll_interval_s: Seconds between status checks (default 15, minimum 5). timeout_s: Give up and return the last-seen status after this many seconds (default 600).
{ "type": "object", "title": "submit_and_wait_for_requestArguments", "required": [ "request_json" ], "properties": { "timeout_s": { "type": "integer", "title": "Timeout S", "default": 600 }, "request_json": { "type": "string", "title": "Request Json" }, "poll_interval_s": { "type": "integer", "title": "Poll Interval S", "default": 15 } } }arguments 23 linespurge_request unknown never probed
Delete a subsetting request and its output files. Requires GDEX_TOKEN. Args: rindex: Request index/ID to purge
{ "type": "object", "title": "purge_requestArguments", "required": [ "rindex" ], "properties": { "rindex": { "type": "string", "title": "Rindex" } } }arguments 13 linesget_dataset_metadata unknown never probed
Return full metadata for a GDEX dataset (parameters, temporal range, spatial coverage, etc.). Args: dsid: Dataset ID (dNNNNNN), e.g. d083002
{ "type": "object", "title": "get_dataset_metadataArguments", "required": [ "dsid" ], "properties": { "dsid": { "type": "string", "title": "Dsid" } } }arguments 13 linesget_filesearch_grid_files unknown never probed
Search for data files containing "grid" datatype data, filtered by parameter code(s) and optionally by time range, product, grid, or level. Results are paginated; use get_filesearch_result_page with the returned result_id to fetch additional pages. Use get_filesearch_grid_filters first to find valid parameter/product/grid/level codes for this dataset. Args: dsid: Dataset ID (dNNNNNN), e.g. d083002 parameters: Parameter code(s) to search for (required, at least one) valid_datetime_min: Restrict to data valid on/after "YYYY-MM-DD HH:MM" valid_datetime_max: Restrict to data valid on/before "YYYY-MM-DD HH:MM" products: Restrict to specified product code(s) grids: Restrict to specified grid code(s) levels: Restrict to specified vertical level code(s)
{ "type": "object", "title": "get_filesearch_grid_filesArguments", "required": [ "dsid", "parameters" ], "properties": { "dsid": { "type": "string", "title": "Dsid" }, "grids": { "type": "array", "items": { "type": "string" }, "title": "Grids", "default": [] }, "levels": { "type": "array", "items": { "type": "string" }, "title": "Levels", "default": [] }, "products": { "type": "array", "items": { "type": "string" }, "title": "Products", "default": [] }, "parameters": { "type": "array", "items": { "type": "string" }, "title": "Parameters" }, "valid_datetime_max": { "type": "string", "title": "Valid Datetime Max", "default": "" }, "valid_datetime_min": { "type": "string", "title": "Valid Datetime Min", "default": "" } } }arguments 55 lines
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
