## Quality 87/100 (good)

### protocol: 75 (weight 25)

- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 8 of 8 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,622 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: 67 (weight 15)

- pass `deps.known_vulns`: no known advisory in 176 resolved packages
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: @opendata.cat/mcp-server@0.6.1 resolved: 176 packages

- tools: 8, about 1,622 tokens to load them all

## Tools (8)

- `get_dataset_info`: Get complete metadata for a dataset: fields with types and descriptions, API endpoint, license, available formats and last update. Call after search_datasets to get full details of a specific dataset.
- `list_categories`: List all dataset categories and themes with counts per portal. Great first step to discover what data types are available before searching with search_datasets. Returns total datasets, count per portal and category list with counts. No parameters required.
- `list_dataset_fields`: List fields of a dataset with name, data type and description. Call before query_dataset to know which fields and filters are available.
- `list_portals`: List all 13 indexed open data portals with dataset counts. Catalan portals (Generalitat, Barcelona, Diba, AOC, Reus, Girona, FGC, Idescat, Renfe) + Spanish national sources with Catalonia focus (INE statistics, REE energy, SEPE employment, CNMC fuel prices). No parameters required.
- `query_dataset`: Query real data from a dataset. Check instructions for featured dataset_ids and NOTES section for common filter patterns (municipal budgets, contracts, weather, energy, fuel prices).
- `related_datasets`: Find related datasets from OTHER portals. Great for discovering complementary data: if you're looking at air quality from Generalitat, it may suggest traffic data from Barcelona or emissions from AOC. Relations are computed by thematic similarity across portals.
- `search_datasets`: Search datasets by free text. IMPORTANT: check server instructions first — many common queries have a direct dataset_id you can use with query_dataset without searching. Only use search_datasets when you don't know which dataset you need.
- `search_radioteca`: 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 across episode titles, descriptions (which include 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 the absolute 'url' in your reply for traceability — never paraphrase without linking.
