## 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 2026-08-03.

- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (96 of 100), 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 (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 (MIT).
  - Actively maintained (last published 10 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 54/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 700 tokens (~43/item across 16 items; 16 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**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **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 62, +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.

## MCP tools (16)

### `remember` (~81 tokens)

- `tags` (array)
- `ttl` (number)
- `type` (string, required)

Input parameters:

- `query` (string, required)
- `token_budget` (integer)
- `type` (string)

### `forget` (~28 tokens)

Delete a memory by id. Returns whether a memory was removed.

Input parameters:

- `memory_id` (string, required)

### `search` (~72 tokens)

Search vault notes by relevance; returns ranked snippets within an optional token_budget (never whole notes). mode: hybrid (default) | lexical | semantic. Expand with get_note.

Input parameters:

- `mode` (string)
- `query` (string, required)
- `token_budget` (integer)
- `top_k` (integer)

### `get_note` (~55 tokens)

Fetch a note progressively: outline (headings) | frontmatter_only | full, with an optional max_tokens ceiling.

Input parameters:

- `format` (string)
- `max_tokens` (integer)
- `note_id` (string, required)

### `graph_query` (~52 tokens)

Traverse the wikilink graph: links (outgoing) | backlinks | neighbors (both directions, to depth).

Input parameters:

- `depth` (integer)

- `relation` (string, required)

### `list_notes` (~18 tokens)

List all note ids with their titles and paths.

### `propose_changes` (~44 tokens)

Input parameters:

- `ops` (array, required)

### `commit_changes` (~38 tokens)

Atomically apply a previously proposed change_id (all-or-nothing). Returns a version_id usable with revert.

Input parameters:

- `change_id` (string, required)

### `revert` (~29 tokens)

Undo a committed change by version_id, restoring the prior note state.

Input parameters:

- `version_id` (string, required)

### `create_note` (~52 tokens)

Create a note (auto-committed). Fails if it already exists. Returns a version_id.

Input parameters:

- `content` (string, required)
- `frontmatter` (object)

Update a note body and/or frontmatter (auto-committed). Returns a version_id.

Input parameters:

- `content` (string)
- `frontmatter` (object)
- `note_id` (string, required)

### `link` (~45 tokens)

Append a [[to]] wikilink to the `from` note (idempotent). Returns a version_id.

Input parameters:

- `from` (string, required)
- `to` (string, required)

### `tag` (~38 tokens)

Add a tag to a note (deduplicated). Returns a version_id.

Input parameters:

- `note_id` (string, required)
- `tag` (string, required)
