## 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 2026-08-04.

- **Supply Chain Security**: 76/100
  - No malware found by supply-chain analysis.
  - CVE check failed: a known medium-severity CVE affects hono 4.12.33, reached via @modelcontextprotocol/sdk > hono. A fixed version is available.
  - Runs a script at install time (postinstall) that we could not recognise. It may be perfectly ordinary, but we do not read the published tarball, so we cannot say what it does.
  - Only part of the dependency tree could be resolved (96 of 100), 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 (Apache-2.0).
  - Actively maintained (last published 164 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 80/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2577 tokens (~151/item across 17 items; 16 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 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 (16)

### `search_legislation` (~200 tokens)

Search Finnish statutes and regulations by keyword.

Searches provision text using FTS5 with BM25 ranking. Supports boolean operators (AND, OR, NOT), phrase search ("exact phrase"), and prefix matching (term*).

Returns matched provisions with snippets, relevance scores, and document metadata.

When NOT to use: If you already know the exact statute number and provision, use get_provision instead. If you need a comprehensive multi-source answer, use build_legal_stance.

Input parameters:

- `as_of_date` (string): Optional historical date filter (YYYY-MM-DD). Returns versions valid on that date.
- `document_id` (string): Filter to a specific statute by statute number (e.g., "1050/2018" or "2018:218")
- `limit` (number): Maximum results
- `query` (string, required): Search query in Finnish or English. Supports FTS5 syntax.
- `status` (string): Filter by document status

### `get_provision` (~268 tokens)

Retrieve a specific provision from a Finnish statute.

Specify the statute number and either chapter+section or provision_ref directly.
Examples:
  \- document_id="1050/2018", chapter="1", section="1" → 1 luku 1 §
  \- document_id="1050/2018", provision_ref="1:1" → same result
  \- document_id="434/2003", section="6" → 6 § (flat lookup)

Omit chapter/section/provision_ref to get all provisions in the statute.

When NOT to use: If you are searching by keyword and don't know the exact statute/provision, use search_legislation instead.

Input parameters:

- `as_of_date` (string): Optional historical date (YYYY-MM-DD). Returns the provision text valid on that date.

Build a comprehensive set of citations for a legal question.

Searches across statutes, case law, and preparatory works simultaneously to aggregate relevant citations. Use this for broad legal research questions.

- `has_finnish_implementation` (boolean): Filter by Finnish implementation existence
- `limit` (number): Maximum results
- `query` (string): Keyword search (title, short name, CELEX, description)
