## 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 2026-08-20.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs setuptools.build_meta at install time, a recognised native-build step with no shell scripting around it.
  - 0 of 5 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 48/100
  - 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 0 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 255 tokens (~85/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 96/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 88% of tool parameters carry a description.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

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.

### 2026-08-20 (score 66)

First indexed and scored.

## MCP tools (3)

### `verify_journal` (~63 tokens)

Check whether an Aileron journal is intact. Returns whether the hash chain verifies, how many events it holds, and the sequence number of the first bad event if it was tampered with.

Input parameters:

- `journal` (string, required): Journal filename, relative to the served root.

### `query_events` (~137 tokens)

Search a journal for recorded tool calls. Filter by tool name, status (ok, error, blocked), or a time range. Returns the matching events. Tool arguments appear as digests unless the journal was recorded with content capture enabled.

Input parameters:

- `journal` (string, required): Journal filename, relative to the served root.
- `limit` (integer): Maximum events to return (default 50, max 200).
- `since` (string): RFC3339 lower bound, inclusive.
- `status` (string)
- `tool_name` (string): Exact tool name to match.
- `until` (string): RFC3339 upper bound, inclusive.

### `explain_rule` (~55 tokens)

Describe the bundled detection rules: what each one matches, its severity, and whether it blocks or only alerts. Omit rule_id to list all of them.

Input parameters:

- `rule_id` (string): For example aileron-130.
