## 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)

  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1244 tokens (~138/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 40/100
  - Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.

  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.

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.

### 2026-09-20 (score 53, +1)

No change was recorded against any check on this day. Stability & Change Management went from 33 to 37. That category is still filling its 30-day observation window: 10 days of observed history at the previous scan, 11 at this one. The score rises as the window fills, whether or not the server changes.

First indexed and scored.

## MCP tools (9)

### `license_status` (~23 tokens)

License status

Show whether this server runs in free or Pro mode and where to upgrade.

### `license_activate` (~42 tokens)

Activate license

Activate a Pro license key (format MCPL1.xxx.yyy). Verified offline and saved locally.

Input parameters:

- `key` (string, required): License key from the checkout confirmation page

### `zip_create` (~272 tokens)

Create a zip archive

Call this tool to pack files or a whole directory (with glob patterns) into a new .zip at out_path. Entry names are always relative, so the archive cannot write outside where it is unpacked.

Input parameters:

- `dir` (string): Pack this directory's tree; entry names are relative to it
- `exclude` (array): Drop entries matching one of these globs, applied after patterns
- `level` (integer): Deflate level 0 to 9, default 6. 0 stores without compressing
- `out_path` (string, required): Where to write the .zip. A directory, a missing parent or an existing file without overwrite is refused before anything is packed
- `overwrite` (boolean): Replace out_path if a file is already there. Default false: an existing file is never overwritten
- `password` (string): Not supported. Passing it is refused rather than ignored, so no one believes an archive is encrypted when it is not
- `paths` (array): Files to pack, each stored under its own file name. A directory here contributes its whole tree under its own name
- `patterns` (array): Only entries matching one of these globs (* and ? inside a segment, ** across segments; a pattern with no slash also matches the file name at any depth)

### `zip_list` (~143 tokens)

List a zip archive

Call this tool to list an archive's entries with sizes, compressed sizes and ratios, and to flag what is dangerous in it: absolute paths, .., symlinks, encrypted entries, duplicate names and compression bombs.

Input parameters:

- `limit` (integer): How many entries to print, largest first (default 50). The totals always cover every entry
- `max_ratio` (number): Flag an entry whose uncompressed/compressed ratio is above this. Default 100
- `path` (string, required): Path to the .zip file. Read-only: the archive is never modified and nothing is extracted
- `patterns` (array): Only entries matching one of these globs

### `zip_extract` (~251 tokens)

Extract a zip archive

Call this tool to unpack an archive into out_dir. Traversal, absolute-path and symlink entries are refused, a size and ratio cap stops a zip bomb, and dry_run reports exactly what would be written.

Input parameters:

- `dry_run` (boolean): Report what would be written, byte counts included, and write nothing
- `max_ratio` (number): Refuse an entry whose uncompressed/compressed ratio is above this. Default 100
- `max_total_mb` (number): Refuse if the selected entries declare more than this uncompressed. Default 1024
- `out_dir` (string, required): Directory to unpack into. It is created if missing; every file written is checked to land inside it
- `overwrite` (boolean): Replace files that already exist in out_dir. Default false: the whole extraction is refused if any would be replaced
- `path` (string, required): Path to the .zip file
- `patterns` (array): Only entries matching one of these globs (* and ? inside a segment, ** across segments)
- `skip_unsafe` (boolean): Skip the dangerous entries and extract the rest, naming what was skipped. Default false: one bad entry refuses the whole archive

### `zip_add` (~183 tokens)

Add files to a zip

Call this tool to add files to an existing archive. The archive is rebuilt from its entries and written tmp-then-rename, so a failure part way leaves the original file exactly as it was.

Input parameters:

- `level` (integer): Deflate level 0 to 9 for the new entries, default 6
- `password` (string): Not supported. Passing it is refused rather than ignored
- `path` (string, required): Path to the existing .zip file
- `paths` (array, required): Files to add, each stored under its own file name. A directory contributes its tree under its own name
- `prefix` (string): Put the new entries under this folder inside the archive, for example "invoices"
- `replace` (boolean): Replace an entry whose name is already in the archive. Default false: a name clash is refused and nothing is changed

### `zip_extract_text` (~115 tokens)

Read one entry as text

Call this tool to read one text entry out of an archive without unpacking anything: give the entry name and the text comes back inline. Binary entries are refused by name rather than printed as noise.

Input parameters:

- `entry` (string, required): Exact entry name, as zip_list prints it. A glob is accepted when it matches exactly one entry
- `max_chars` (integer): Stop after this many characters (default 200000). The answer says when it was cut
- `path` (string, required): Path to the .zip file

### `zip_bundle_month` (~160 tokens)

Bundle a month of documents

Call this tool to zip one month of invoices, quotes and exports written by the sibling servers into their default output folders. Best effort: it names every folder it looked in and what it found.

Input parameters:

- `dry_run` (boolean): Report what would go in and write nothing
- `month` (string): Month as YYYY-MM. Default: this month. Files are chosen by their modification date
- `out_path` (string): Where to write the .zip. Default: <data dir>/bundles/<month>.zip
- `overwrite` (boolean): Replace out_path if it exists. Default false
- `servers` (array): Only these sibling servers: invoice, quotes, expense-tracker, docx, resume. Default: all five

### `zip_history` (~55 tokens)

Archives created

List the archives this server created, newest first, with their entry counts and sizes, plus how many of this month's free allowance are left.

Input parameters:

- `limit` (integer): How many rows to show, newest first (default 20)
