## 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 2026-09-20.

- **Supply Chain Security**: 23/100
  - Malware scan not yet available for this package.
  - Known CVEs were checked across the 97 of 97 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - 31 of 97 dependencies flagged as unhealthy.
- **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 2 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 74/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1320 tokens (~146/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**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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.
- **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.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); 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.

### 2026-09-17 (score 47)

First indexed and scored.

## MCP tools (9)

### `license_status` (~54 tokens)

License status

Report this server's licence state: product, tier free or pro, licence id, expiry, the key source and the upgrade URL. No arguments, no network. Explains a free-tier refusal; license_activate installs a key.

### `license_activate` (~71 tokens)

Activate license

Activate a Pro key (MCPL1.xxx.yyy) from checkout: verified offline against a built-in public key, saved to your config file. A wrong, malformed or expired key is refused, unsaved. license_status reads it back.

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` (~144 tokens)

List a zip archive

Call this tool to list an archive's entries with sizes and ratios and flag what is dangerous: absolute paths, .., symlinks, encrypted entries, duplicate names and bombs. Read-only. Run it before zip_extract.

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` (~181 tokens)

Add files to a zip

Call this tool to add files to an existing archive under their own names, or under prefix. A name clash is refused unless replace. An archive holding unsafe entries is refused rather than rewritten.

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` (~72 tokens)

Archives created

List the archives this server created, newest first, with entry counts, sizes and paths, plus how much of the free 20 a month is used. It reads the register only; use zip_list to see inside one.

Input parameters:

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