Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security66
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS not yet verified: we couldn't determine whether a plaintext access path exists. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability64
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 5530 tokens (~460/item across 12 items; 8 tools + 4 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities20
- Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 2 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

get_dataset_info ~108
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 ~53
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_dataset_fields ~60
List fields of a dataset with name, data type and description. Call before query_dataset to know which fields and filters are available.

|---|---|---|---|
| dataset_id | string | yes | Unique dataset identifier in 'portal:id' format. Obtained from search_datasets results. |
No output schema declared.
No examples provided.
list_portals ~80

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
query_dataset ~223
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).
| Name | Type | Req | Description |
|---|---|---|---|
| dataset_id | string | yes | Unique dataset identifier in 'portal:id' format. Obtained from search_datasets results. |
| filters | object | — | Key-value filters where the key is the field name and the value is the filter value. Examples: {"municipi": "Barcelona"}, {"any": "2024"}, {"NOM_ENS": "Ajuntament de Tiana"}. Use list_dataset_fields… |
