Scored 2026-08-03.

- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to OksigeniaSL/checker-mcp).
  - Clear OSI-approved license (GPL-3.0-or-later).
  - Actively maintained (last published 12 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 319 tokens (~106/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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.
  - Structured output schemas are declared (33% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 80, +1)

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.

- `lang` (string): Report language: 'es' or 'en'. Defaults to $OKSIGENIA_LANG or 'en'.

Output parameters:

- `checks` (array)
- `domain` (string)
- `grade` (string)
- `lang` (string)
- `score` (number)
- `summary` (object)

### `list_checks` (~66 tokens)

List available checks

List every check the Oksigenia Checker performs, grouped by category, with the reason each one matters. Useful to know what check ids exist.

Input parameters:

- `lang` (string): Report language: 'es' or 'en'. Defaults to $OKSIGENIA_LANG or 'en'.

### `explain_check` (~90 tokens)

Explain a check and how to fix it

Given a check id (see list_checks), explain what it verifies, why it matters, and how to remediate a failure.

Input parameters:

- `check_id` (string, required): The check id, e.g. 'ssl', 'dmarc', 'hsts_preload'.
- `lang` (string): Report language: 'es' or 'en'. Defaults to $OKSIGENIA_LANG or 'en'.
