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 Security0
  • 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 could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
  • Install-script risk not yet assessed.Unverified

  • 15% 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

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.

MCP tools · 21 exposed · ~1,515 tokens

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 →

Tool Tokens
document_apply ~68

Apply a proposal from document_propose_replacement to the document in this session's cabin (not to your original file). Stale proposal (the document moved on) is refused by the engine — propose again. Repeating an applied proposal is a no-op.

document_describe ~36

Name, pages, paragraphs, words, number of comments and tracked changes, whether track changes is on. For documents; call first.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

document_export_pdf ~59

Lay out the document as it is now in this session's cabin (after applied proposals, or as opened) and return a PDF download link valid for 24 hours, plus the page count. Documents only; for workbooks use document_save_copy.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

document_find ~31

Paragraphs containing the text (case-insensitive), with snippets around the match.

document_open ~72

Open one of the demo files by name: documents footnotes, comments, forms, rtl, wild-horse, workshop; workbooks workbook, functions, xtools. Default is footnotes. For your own file use document_open_file. Opens a separate editor cabin for this session.

NameTypeReqDescription
slugstringyes–

No output schema declared.

No examples provided.

document_open_file ~200

Open YOUR file in a private editor cabin for this session: a .docx/.doc/.odt document or an .xlsx/.xlsm/.xlsb/.xls/.ods workbook, up to 50 MB. Give exactly one of: url (https link the server can fetch), base64 (file bytes; then name with the extension is required), path (a file on this machine). Nothing in the file is executed. The file is kept for 24 hours and then deleted. After opening, use document_* tools for a document or sheet_* / macro_* / query_* / workbook_inspect for a workbook; sheet_propose_edits → sheet_apply and document_propose_replacement → document_apply change the copy in the cabin; document_save_copy returns a download link of the edited file.

document_propose_replacement ~91

Propose the full new text of one paragraph (paragraph_index from document_read). Nothing changes yet: the editor core builds the change on a copy and returns before/after plus checks (numbers, dates, links kept). Then call document_apply with the proposal_id. Read the paragraph first.

document_read ~73

Paragraph text as a window: from = index of the first paragraph (0-based), count = how many (max 40). The answer carries next — where to continue, null at the end. A missing paragraph is a refusal, not an invention.

document_save_copy ~99

Write the document or workbook as it is now in this session's cabin (after applied proposals) to a copy and return a download link valid for 24 hours. Your original file is never touched. A workbook with macros comes back as .xlsm with the VBA project intact; a document keeps its styles, comments and tracked changes.

NameTypeReqDescription

No output schema declared.

macro_list ~30

List VBA modules and runnable macros (entry points) in this workbook with their route and blockers. Runs nothing.

Input schema present but exposes no named parameters.

No examples provided.

query_list ~33

List Power Query queries in this workbook: names, step chain, load target, connections. Reads only; refreshes nothing.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

sheet_apply ~71

Apply a proposal from sheet_propose_edits to the workbook in this session's cabin (not to your original file); the engine recalculates. Refused if the workbook revision moved on since the proposal — propose again. Repeating an applied proposal is a no-op.

NameTypeReqDescription
proposal_idstringyes–

No output schema declared.

No examples provided.

sheet_describe ~57

Workbook overview: every sheet tab with its used range, the current revision, and the header row of the sheet that is open. Call this first, then pass the tab name you need as "sheet" to sheet_read and sheet_find.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

sheet_find ~89

Find cells whose value or formula contains the text (case-insensitive) in the used range of a sheet. ALWAYS pass "sheet" with the exact tab name when the workbook has more than one sheet: without it only the sheet that happens to be open is searched.

NameTypeReqDescription
querystringyes–
sheetstring–Exact tab name. Required when the workbook has more than one sheet.

No output schema declared.

No examples provided.

sheet_propose_edits ~114

Propose new contents for up to 20 cells (formulas like =SUM(B2:B9), or numbers/text). Nothing changes in the workbook: the engine previews the edits on the current revision and reports what would change and whether errors appear; the person decides whether to apply. Read the cells first. Do not overwrite input numbers unless the task says so. Then call sheet_apply with the proposal_id.

NameTypeReqDescription
editsarrayyes–
reasonstring––
sheetstring––

No output schema declared.

No examples provided.

sheet_read ~124

Read a rectangular range like A1:F20 (max 60 rows × 26 columns): values and formulas. Empty cells are omitted. ALWAYS pass "sheet" with the exact tab name when the workbook has more than one sheet — without it you read whichever sheet happens to be open, and the answer will quietly be about the wrong sheet. Call sheet_describe first if you do not know the tab names.

NameTypeReqDescription
rangestringyes–
sheetstring–Exact tab name, e.g. "Logical". Required when the workbook has more than one sheet.

No output schema declared.

No examples provided.

workbook_inspect ~102

Map the whole application model of this workbook in one call: sheets; VBA modules, procedures, which can run here and which are blocked and why; event handlers; external objects (CreateObject) and Windows API (Declare) dependencies; project references; Power Query queries; data connections; form controls, ActiveX, embedded objects (preserved). Runs nothing. Call this first for questions like 'how is this workbook built' or 'what does it depend on'.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.
