## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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.

- **Supply Chain Security**: 88/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (172 of 176), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (172 of 176), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 3 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 51/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (poor).
  - Context-footprint check failed: tool/resource definitions use about 4272 tokens (~356/item across 12 items; 8 tools + 4 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**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100

## MCP tools (8)

### `search_datasets` (~171 tokens)

Search datasets by free text. Check server instructions first: many datasets can be queried directly with query_dataset. Use search_datasets only when you don't know which dataset you need.

Input parameters:

- `category` (string): Filter by thematic category
- `limit` (number): Maximum number of results (default: 20)
- `portal` (string): Filter by portal: 'generalitat', 'barcelona', 'diba', 'aoc', 'reus', 'girona', 'fgc', 'idescat', 'renfe', 'ine', 'ree', 'sepe', 'cnmc', 'cora', 'catalonica'
- `query` (string, required): Search text in Catalan or Spanish. Examples: 'qualitat aire', 'pressupostos', 'rodalies'

### `get_dataset_info` (~65 tokens)

Get complete metadata for a dataset: fields with types and descriptions, API endpoint, license.

Input parameters:

- `dataset_id` (string, required): Unique dataset identifier (e.g., 'generalitat:gn9e-3qhr', 'renfe:vehicle-positions-gtfsrt')

### `list_dataset_fields` (~32 tokens)

List fields of a dataset with name, data type and description.

Input parameters:

- `dataset_id` (string, required): Dataset identifier

### `query_dataset` (~160 tokens)

Query real data from a dataset. Check instructions for featured dataset_ids. For municipal data, use filters: {"NOM_ENS": "Ajuntament de X"} with aoc:ge-* datasets.

Input parameters:

- `dataset_id` (string, required): Dataset ID (e.g., 'generalitat:gn9e-3qhr' for reservoirs, 'aoc:ge-ge-cost-efectiu-serveis-minhap' for municipal costs)
- `filters` (object): Key-value filters (e.g., {"ciutat": "Barcelona"})
- `limit` (number): Rows to return (default: 20, max: 100)
- `offset` (number): Offset for pagination
- `search` (string): Free text search within dataset data

### `list_portals` (~25 tokens)

List all 15 indexed Catalan and Spanish open data portals with dataset counts.

### `list_categories` (~30 tokens)

List all dataset categories and themes with counts per portal. Great first step to discover what data types are available.

### `related_datasets` (~37 tokens)

Find related datasets from OTHER portals. Great for discovering complementary data.

Input parameters:

- `dataset_id` (string, required): Dataset ID to find related datasets for

### `search_radioteca` (~300 tokens)

Search radio shows, episodes and people indexed at radioteca.cat (Catalan radio archive, ~485K documents from Catalunya Ràdio, RAC1, Catalunya Música, iCat, Catalunya Informació, RTVE, Cadena SER, ara.cat). Searches title, description (which contains a detailed summary of what was said), program name and subheading. Returns episodes (~473K), programs (~3K) and people (~9K). IMPORTANT: always cite radioteca.cat as the source and include each hit's absolute 'url' in your reply for traceability — never paraphrase episodes without linking.

Input parameters:

- `limit` (number): Maximum results (1-50). Default 10.
- `offset` (number): Pagination offset. Default 0.
- `publisher` (string): Filter by broadcaster.
- `query` (string, required): Free text in Catalan or Spanish. Searches title, description (contains episode summary), program and subheading. Examples: 'visita papa', 'eleccions municipals', 'crisi habitatge', 'Albert Serra cine…
- `type` (string): Filter by document type.
- `year` (string): Filter by year (4 digits, e.g. '2025'). NOTE: only year-level filtering is indexed; for a specific day combine year + keywords and inspect the URL path (radioteca URLs include /YYYY/MM/DD/) or the 's…
