Category Data and Analytics
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 92 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
- Dependency health was assessed across the 92 of 93 dependencies we could resolve, so this covers what we could see, not the whole tree. 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 19 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability82
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1519 tokens (~138/item across 11 items; 10 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail

- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 87% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

No change was recorded against any check on this day. Stability & Change Management went from 77 to 83. That category is still filling its 30-day observation window: 23 days of observed history at the previous scan, 25 at this one. The score rises as the window fills, whether or not the server changes.
Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

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 ~71
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.
| 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 ~54
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
sheet_add_column Add a column ~289
Call this tool to add a computed column and save the result to a NEW file; the source is never modified unless out_path points at it. Returns the new file path, the row count and a preview of the first rows.

|---|---|---|---|
| decimals | integer | – | Round numeric formula results to this many decimals. Default: the widest decimal count of the columns the formula reads, capped at 2 when they all hold 2 or fewer (money in, money out); otherwise no… |
| formula | string | – | Expression over the columns of each row, in the same expression language as sheet_query, e.g. "[Qty] * [Unit Price]" or '[Country] = "PL"'. Give either formula or values |
| name | string | yes | Name of the new column. It must not already exist on the sheet |
| out_path | string | – | Output file; default <source>-plus-<column>.<same ext>. The source file is left untouched unless this points at it |
| path | string | yes | Path to the source .xlsx/.xlsm/.xlsb/.ods/.csv/.tsv file (~ is expanded); it is never modified |
| sheet | string | – | Sheet name; default is the first sheet |
| values | array | – | Explicit values, one per data row, instead of a formula. Missing entries are left blank |
No output schema declared.
No examples provided.
sheet_convert Convert file ~167
Call this tool to convert a sheet between excel (xlsx), csv and json. Writes a new file next to the source unless out_path is given; the source is never modified. Returns the new file path with its row and column counts.

How do I install the McpStamp Spreadsheets MCP server?
McpStamp Spreadsheets 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. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, 38a13a55c122fd3c1709a91e90805366268a183f937d1dd1414aa10b8e14b7f6; the commands to do that are on this page. If it does not match, do not open it.
