Category Documents and Files
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. How we score → Why this is hard to score →
Supply Chain Security23
- No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
- Known CVEs were checked across the 93 of 93 dependencies we could resolve, so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- 30 of 93 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 58 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability76

- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
license_activate Activate license ~42
Activate a Pro license key (format MCPL1.xxx.yyy). Verified offline and saved locally.
| Name | Type | Req | Description |
|---|---|---|---|
| key | string | yes | License key from the checkout confirmation page |
No output schema declared.
No examples provided.
license_status License status ~23
Show whether this server runs in free or Pro mode and where to upgrade.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
zip_add Add files to a zip ~183
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | Path to the existing .zip file |
| paths | array | yes | 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 |
No output schema declared.
No examples provided.
zip_bundle_month Bundle a month of documents ~160
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 |
No output schema declared.
No examples provided.
zip_create Create a zip archive ~272
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | 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) |
No output schema declared.
No examples provided.
zip_extract Extract a zip archive ~251
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | 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 | yes | 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 |
No output schema declared.
No examples provided.
zip_extract_text Read one entry as text ~115
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.
| Name | Type | Req | Description |
|---|---|---|---|
| entry | string | yes | 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 | yes | Path to the .zip file |
No output schema declared.
No examples provided.
zip_history Archives created ~55
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | How many rows to show, newest first (default 20) |
No output schema declared.
No examples provided.
zip_list List a zip archive ~143
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | 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 |
No output schema declared.
No examples provided.
How do I install the com.bestremotetools/archive-zip-unzip-bomb-guard MCP server?
com.bestremotetools/archive-zip-unzip-bomb-guard ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. The MCP registry declares no SHA-256 for this bundle, so there is no published digest to check the download against.
