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.
ckan_package_search unknown never probed
Search for datasets (packages) on a CKAN server using Solr query syntax. Supports full Solr search capabilities including filters, facets, and sorting. Use this to discover datasets matching specific criteria. Note on parser behavior: Some CKAN portals use a restrictive default query parser that can break long OR queries. For those portals, this tool may force the query into 'text:(...)' based on per-portal config. You can override with 'query_parser' to force or disable this behavior per request. Important - Date field semantics: - issued: publisher's content publish date when available (best proxy for "created/published") - modified: publisher's content update date when available - metadata_created: CKAN record creation timestamp (publish time on source portals, harvest time on aggregators; fallback for "created" if issued missing) - metadata_modified: CKAN record update timestamp (publish time on source portals, harvest time on aggregators; use for "updated/modified in last X") Natural language mapping (important for tool callers): - "created"/"published" -> prefer issued; fallback to metadata_created - "updated"/"modified" -> prefer modified; fallback to metadata_modified - For "recent in last X", consider using content_recent (issued with metadata_created fallback) Content-recent helper: - content_recent: if true, rewrites the query to use issued with a fallback to metadata_created when issued is missing. - content_recent_days: window for content_recent (default 30 days). Args: - server_url (string): Base URL of CKAN server (e.g., "https://dati.gov.it/opendata") - q (string): Search query using Solr syntax (default: "*:*" for all) - fq (string): Filter query (e.g., "organization:comune-palermo") IMPORTANT — Solr fq syntax rules: 1. OR inside a single field: use field:(val1 OR val2), NOT field:val1 OR field:val2. Wrong: fq=type:"A" OR type:"B" → silently ignored, returns entire catalog. Right: fq=type:("A" OR "B") 2. CKAN extras fields are indexed as extras_fieldname, not fieldname. e.g. to filter on extra field "hvd_category" use fq=extras_hvd_category:"<value>" - rows (number): Number of results to return (default: 10, max: 1000) - start (number): Offset for pagination (default: 0) - page (number): Page number (1-based); alias for start. Overrides start if provided. - page_size (number): Results per page when using page (default: 10, max: 1000) - sort (string): Sort field and direction (e.g., "metadata_modified desc") - facet_field (array): Fields to facet on (e.g., ["organization", "tags"]) - facet_limit (number): Max facet values per field (default: 50) - include_drafts (boolean): Include draft datasets (default: false) - query_parser ('default' | 'text'): Override search parser behavior - response_format ('markdown' | 'json'): Output format Returns: Search results with: - count: Number of results found - results: Array of dataset objects - facets: Facet counts (if facet_field specified) - search_facets: Detailed facet information Query Syntax (parameter q): Boolean operators: - AND / &&: "water AND climate" - OR / ||: "health OR sanità" - NOT / !: "data NOT personal" - +required -excluded: "+title:water -title:sea" - Grouping: "(title:water OR title:climate) AND tags:environment" Wildcards: - *: "title:environment*" (matches environmental, environments, etc.) - Note: Left truncation (*water) not supported Fuzzy search (edit distance): - ~: "title:rest~" or "title:rest~1" (finds "test", "best", "rest") Proximity search (words within N positions): - "phrase"~N: "title:"climate change"~5" Range queries: - Inclusive [a TO b]: "num_resources:[5 TO 10]" - Exclusive {a TO b}: "num_resources:{0 TO 100}" - One side open: "metadata_modified:[2024-01-01T00:00:00Z TO *]" Date math: - NOW-1YEAR, NOW-6MONTHS, NOW-7DAYS, NOW-1HOUR - NOW/DAY, NOW/MONTH (round down) - Combined: "metadata_modified:[NOW-2MONTHS TO NOW]" - Example: "metadata_created:[NOW-1YEAR TO *]" - IMPORTANT: NOW syntax works on metadata_modified and metadata_created fields - For 'modified' and 'issued' fields, NOW syntax is auto-converted to ISO dates - Manual ISO dates always work: "modified:[2026-01-15T00:00:00Z TO *]" Field existence: - Exists: "field:*" or "field:[* TO *]" - Not exists: "NOT field:*" or "-field:*" Boosting (relevance scoring): - Boost term: "title:water^2 OR notes:water" (title matches score higher) - Constant score: "title:water^=1.5" Examples: - Search all: { q: "*:*" } - By tag: { q: "tags:sanità" } - Boolean: { q: "(title:water OR title:climate) AND NOT title:sea" } - Wildcard: { q: "title:environment*" } - Fuzzy: { q: "title:health~2" } - Proximity: { q: "notes:"open data"~3" } - Date range: { q: "metadata_modified:[2024-01-01T00:00:00Z TO 2024-12-31T23:59:59Z]" } - Date math: { q: "metadata_modified:[NOW-6MONTHS TO *]" } - Date math (auto-converted): { q: "modified:[NOW-30DAYS TO NOW]" } - Published in 2025 (content date): { fq: "issued:[2025-01-01T00:00:00Z TO 2025-12-31T23:59:59Z]" } - First appeared on portal in 2025: { fq: "metadata_created:[2025-01-01T00:00:00Z TO 2025-12-31T23:59:59Z]" } - Recent content (issued w/ fallback): { q: "*:*", content_recent: true, content_recent_days: 180 } - Field exists: { q: "organization:* AND num_resources:[1 TO *]" } - Boosting: { q: "title:climate^2 OR notes:climate" } - Filter org: { fq: "organization:regione-siciliana" } - Filter extras field (correct): { fq: "extras_hvd_category:"http://data.europa.eu/bna/c_ac64a52d"" } - Filter extras OR (correct): { fq: "extras_hvd_category:("http://data.europa.eu/bna/c_ac64a52d" OR "http://data.europa.eu/bna/c_dd313021")" } - Get facets: { facet_field: ["organization"], rows: 0 } Query language: Before searching a portal, check its locale via ckan_status_show (field: "Portal Locale" / locale_default). Translate query terms to the portal's language — searching in English on a non-English portal returns 0 results. Examples: locale "it" → Italian terms; "uk_UA" → Ukrainian (Cyrillic); "fr_FR" → French. Exception: multilingual portals (e.g. data.europa.eu, open.canada.ca) accept EN + native terms joined with OR. Typical workflow: ckan_status_show (check locale) → ckan_package_search (query in portal's language) → ckan_package_show (get full metadata + resource IDs) → ckan_datastore_search (query tabular data)

Find and rank datasets by relevance to a query using weighted fields. Use this instead of ckan_package_search when you want relevance-ranked results with explicit scoring across title, notes, tags, and organization fields. Use ckan_package_search instead when you need Solr filter syntax, facets, or pagination. Uses package_search for discovery and applies a local scoring model. Args: - server_url (string): Base URL of CKAN server (e.g., "https://dati.gov.it/opendata") - query (string): Natural language or keyword query (e.g., "mobilità urbana", "air quality") - limit (number): Number of datasets to return (default: 10) - weights (object): Field weights for scoring — higher weight = more influence on rank Default: title=4, tags=3, notes=2, organization=1, holder=4, publisher=2, coverage=4 coverage: bonus for datasets the portal returned with every query term required (Solr mm=100%); these are fetched first, the rest fills in when they are fewer than limit Note on holder vs organization: on federated catalogs (e.g. dati.gov.it), `organization` is the harvesting catalog (e.g. Regione Puglia), while `holder` (DCAT-AP_IT dct:rightsHolder) is the actual data owner (e.g. Comune di Lecce). Queries like "datasets from a specific Comune" match `holder` correctly; matching only `organization` misses datasets harvested via aggregators. `publisher` (dct:publisher) is scored separately at lower weight as it can contain technical roles ("Redazione OD") rather than the institutional owner. - query_parser ('default' | 'text'): Override search parser behavior - response_format ('markdown' | 'json'): Output format Returns: Ranked datasets with relevance scores and per-field score breakdowns Examples: - { server_url: "https://dati.gov.it/opendata", query: "mobilità" } - { server_url: "...", query: "trasporti", limit: 5, weights: { title: 5, notes: 2 } } - { server_url: "...", query: "defibrillatori Comune di Lecce", weights: { holder: 5 } } Typical workflow: ckan_find_relevant_datasets → ckan_package_show (inspect top results) → ckan_datastore_search (query data)

Get complete metadata for a specific dataset (package). Returns full details including resources, organization, tags, and all metadata fields. Notes: - metadata_modified is a CKAN record timestamp (publish time on source portals, harvest time on aggregators), not the content date. - issued/modified are content dates when provided by the publisher. - JSON output adds metadata_harvested_at (same as metadata_modified).

List all resources in a dataset with a compact summary. Returns a focused table of resources showing format, size, DataStore availability, and download URL. Use this to quickly assess what files a dataset contains before deciding how to access the data. Args: - server_url (string): Base URL of CKAN server - id (string): Dataset ID or name - format_filter (string): Filter resources by format, case-insensitive (e.g., "CSV", "json", "XLSX") - response_format ('markdown' | 'json'): Output format Returns: Compact resource summary with name, ID, format, size, DataStore flag, and URL Examples: - { server_url: "https://dati.gov.it/opendata", id: "dataset-name" } - { server_url: "...", id: "dataset-name", format_filter: "CSV" } Typical workflow: ckan_package_search → ckan_list_resources (assess available files) → ckan_datastore_search (for resources with DataStore=true) When a resource has DataStore=false but its download URL belongs to a different (source) portal, the tool can probe the source portal for DataStore availability and report source_datastore_active and source_portal_url so you can query the data there instead. This probing is OFF by default (it issues extra HTTP requests to hosts taken from the dataset's own resource URLs); set check_source_portal=true to enable it.

Query data from a CKAN DataStore resource. The DataStore allows SQL-like queries on tabular data. Not all resources have DataStore enabled. The response always includes a Fields section listing all available column names and types. Use limit=0 to discover column names without fetching data — do this before using filters to avoid guessing column names and getting HTTP 400 errors. Args: - server_url (string): Base URL of CKAN server - resource_id (string): ID of the DataStore resource - q (string): Full-text search query (optional) - filters (object): Key-value filters (e.g., { "anno": 2023 }) - limit (number): Max rows to return (default: 100, max: 32000) - offset (number): Pagination offset (default: 0) - fields (array): Specific fields to return (optional) - sort (string): Sort field with direction (e.g., "anno desc") - distinct (boolean): Return distinct values (default: false) - response_format ('markdown' | 'json'): Output format Returns: DataStore records matching query, always including available column names and types Examples: - { server_url: "...", resource_id: "abc-123", limit: 0 } ← discover columns first - { server_url: "...", resource_id: "abc-123", limit: 50 } - { server_url: "...", resource_id: "...", filters: { "regione": "Sicilia" } } - { server_url: "...", resource_id: "...", sort: "anno desc", limit: 100 } Typical workflow: ckan_package_search → ckan_package_show (find resource_id with datastore_active=true) → ckan_datastore_search (limit=0 to get columns) → ckan_datastore_search (with filters)

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.
[](https://brick.blue/agent/a526d1a33f1f184f)
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.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
