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 Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 683 tokens (~170/item across 4 items; 4 tools + 0 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
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

get_dataset_metadata Get Nova Scotia Dataset Metadata ~100
Retrieve full schema and metadata for a Nova Scotia Open Data dataset by its 8-character identifier (e.g. '3nka-59nz'). Returns all column field names, data types, and descriptions — essential before calling query_dataset so you know the exact field names to use in $select and $where clauses.
| Name | Type | Req | Description |
|---|---|---|---|
| dataset_id | string | yes | 8-character Socrata dataset identifier (e.g. '3nka-59nz') |
No output schema declared.
No examples provided.
list_categories List Nova Scotia Open Data Categories ~42
Returns all dataset categories and popular tags available on the Nova Scotia Open Data portal. Use this first to discover valid category names before calling search_datasets with a category filter.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
query_dataset Query a Nova Scotia Open Dataset ~332
Run a SoQL query against a Nova Scotia Open Data dataset. SoQL is SQL-like. Key clauses (combine with &): $select=col1,col2 — choose columns $where=field='value' — filter rows (use single quotes for strings) $where=field like '%val%' — partial match $order=field DESC — sort $limit=50 — row count (default 25, max 50000) $offset=50 — pagination $group=field — group by (use with aggregate functions) $q=search term — full-text search Aggregates: count(*), sum(col), avg(col), min(col), max(col) Examples: $where=year='2024'&$order=total DESC&$limit=10 $select=department,count(*)&$group=department&$order=count(*) DESC $where=area like '%Halifax%'&$limit=5 Always call get_dataset_metadata first to find exact field names.
| Name | Type | Req | Description |
|---|---|---|---|
| dataset_id | string | yes | 8-character Socrata dataset identifier (e.g. '3nka-59nz') |
| limit | integer | — | Max rows to return (1–1000, default 25). Ignored if $limit is in soql. |
| soql | string | — | SoQL query string. Multiple clauses joined with '&'. String values in $where must use single quotes: field='value'. Do NOT URL-encode — pass the raw string. |
No output schema declared.
No examples provided.
search_datasets Search Nova Scotia Open Datasets ~209
Search the Nova Scotia Open Data catalog (data.novascotia.ca) for datasets by keyword, category, or tag. Returns dataset names, IDs, descriptions, column names, and direct portal links. Use list_categories first to see valid category and tag names. Use the returned dataset ID with query_dataset or get_dataset_metadata for further exploration.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | — | Filter by exact category name from list_categories (e.g. 'Health and Wellness', 'Lands, Forests and Wildlife', 'Crime and Justice', 'Population and Demographics') |
| limit | integer | — | Maximum number of results to return (1–50, default 10) |
| offset | integer | — | Offset for pagination (default 0) |
| query | string | — | Free-text search query (e.g. 'population', 'fisheries', 'road network') |
| tag | string | — | Filter by an exact tag name from list_categories (e.g. 'population', 'fisheries') |
No output schema declared.
