- **Supply Chain Security**: 86/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (94 of 98), 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 (94 of 98), so this covers what we could see, not the whole tree.

First indexed and scored.

## MCP tools (10)

### `ping` (~30 tokens)

Ping

Health check. Returns 'pong' with the server version and time, confirming the Xentropy MCP connection is live.

### `search_notes` (~68 tokens)

Search notes

Semantic search across your Wall notes. Returns the most relevant notes (id, title, snippet, similarity score); call get_note for full text. Requires a Pro plan.

Input parameters:

- `limit` (integer): Max results (default 10)
- `query` (string, required): What to search your notes for

### `list_notes` (~105 tokens)

List notes

List your Wall notes, newest first. Optional filters: folder, type, archived, and a case-insensitive substring query. Returns compact rows; call get_note for full text.

Input parameters:

- `archived` (boolean): Show archived notes instead of active ones
- `folder` (string): Folder id, or 'unfiled' for notes with no folder
- `limit` (integer)
- `query` (string): Case-insensitive substring filter
- `type` (string)

### `get_note` (~39 tokens)

Get note

Fetch a single note by id with its full text (body or voice transcript), AI summary, and tags.

Input parameters:

- `id` (string, required): Note id

### `get_related_notes` (~44 tokens)

Get related notes

Find notes semantically related to a given note id (most similar first).

Input parameters:

- `id` (string, required): Note id to find neighbors of
- `limit` (integer)

### `list_folders` (~27 tokens)

List folders

List your folders (directories), for use as the `folder` filter in list_notes.

### `create_note` (~106 tokens)

Create note

Create a new Wall note. `body` is required; `title` and `folder` (a directory id to file it into) are optional. Filing into a directory that has a format prompt auto-formats the note. Returns the created note with its id.

### `update_note` (~122 tokens)

Update note

Update an existing note by id. Provide at least one of `title`, `body`, or `folder`; omitted fields are left unchanged. Set `folder` to 'unfiled' to move the note to the root. Returns the updated note.

Input parameters:

- `body` (string): New body text (replaces the current body)
- `folder` (string): Move to this directory id; 'unfiled' for the root; omit to leave as-is
- `id` (string, required): Note id to update
- `title` (string): New title

### `create_directory` (~130 tokens)

Create directory

Create a new directory (folder) to organize notes. `name` is required; optional `parent` (a directory id to nest under), `formatInstructions` (a house-style prompt notes filed here are auto-formatted to), and `icon` (emoji). Returns the created directory with its id.

Input parameters:
