Available components
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. How we score →
Supply Chain Security87
- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency19
- Repository check failed: the declared repository URL returned HTTP 404. See how to fix → View diagnostics → Fail
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 27 days ago).Pass
- Security-disclosure policy not yet verified: we couldn't inspect the source repository.Unverified
Schema Quality & AI Usability72
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 729 tokens (~145/item across 5 items; 5 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 Management23
- Stability observed for 7 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

- 3 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.

The dependency tree was only partially resolved, so these counts may be incomplete.
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
get_attestation Get the signed Gera Vouch attestation for a dataset ~151
Return the cryptographically signed Gera Vouch attestation for a dataset version: a claim object (dataset id, version, row count, SHA-256 content hash over the rows, source, source URL, licence, attribution, as-of, issuer), an Ed25519 signature, and the public key + verification recipe. Any party re-canonicalises the claim (sorted-key UTF-8 JSON) and verifies the signature against the public key — proving the dataset content came from the named source under the named licence and was not altered. This is a proof-of-provenance receipt; it is NOT a warranty of fitness for purpose.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Dataset id (from list_datasets). |
No output schema declared.
No examples provided.
get_dataset Get one dataset’s full metadata + attestation summary ~122
Return everything about one dataset EXCEPT its rows: title, description, coverage, full provenance (source, URL, licence, attribution, as-of, derivation notes), the complete column schema, the row count, and a compact attestation summary (content hash + key id) so you know it is signed. Pass a dataset id from list_datasets. Use query_dataset to fetch the rows, get_attestation for the full signed receipt.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Dataset id, e.g. "uk-council-tax" (from list_datasets). |
No output schema declared.
No examples provided.
get_vouch_public_key Get the public key to verify Gera attestations ~69
Return the Ed25519 public key (+ key_id and verification recipe) used to sign every Gera Vouch dataset attestation, so any party can independently verify a get_attestation receipt. This is the same Gera public key the Gera Data API and Gera Verify MCP publish.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_datasets List all attested Gera open datasets ~135
List the catalog of verified open datasets Gera serves: for each, the id (use it with the other tools), title, source publisher, source URL, licence, reference period (as-of), row count, coverage, and the queryable columns (id, label, type, unit, whether filterable/sortable). Use this first to discover what data is available, then call get_dataset / query_dataset / get_attestation by id. All data is public-domain / OGL v3.0 / CC-BY with attribution.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | — | Optional filter by country/coverage. Defaults to all. |
No output schema declared.
No examples provided.
query_dataset Query a dataset’s rows (filter, sort, paginate) ~252
Fetch verified rows from a dataset with optional single-column filter, sort, and pagination — same semantics as the Gera Data API. filter_column must be a filterable column; for number columns the filter is an exact match, for string columns a case-insensitive substring match. sort_by must be a sortable column. Returns the page of rows plus total/totalPages and the dataset version, so a returned value can be cited precisely (dataset id + version + source). Default page_size 50, max 500. For a full-dataset content hash, page through all rows or use get_attestation.
| Name | Type | Req | Description |
|---|---|---|---|
| filter_column | string | — | Filterable column id to filter on. Omit for no filter. |
| filter_value | string | — | Value to match (exact for number columns, substring for string columns). |
| id | string | yes | Dataset id (from list_datasets). |
| page | integer | — | 1-based page number. Defaults to 1. |
| page_size | integer | — | Rows per page (1-500). Defaults to 50. |
| sort_by | string | — | Sortable column id to sort by. |
| sort_dir | string | — | Sort direction. Defaults to asc. |
