Background: How many MCP packages publish verified provenance →
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 →
document_apply Apply a proposed paragraph replacement ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| proposal_id | string | yes | – |
No output schema declared.
No examples provided.
document_comments Comments and tracked changes ~27
Comments (author, text, anchor, resolved) and tracked changes — up to 50.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
document_describe What the document is ~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 Render the document to 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 Find in the document ~31
Paragraphs containing the text (case-insensitive), with snippets around the match.

|---|---|---|---|
| query | string | yes | – |
No output schema declared.
No examples provided.
document_open Open a demo document or workbook ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | – |
No output schema declared.
No examples provided.
document_open_file Open your own Word document or Excel workbook ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| base64 | string | – | – |
| name | string | – | – |
| path | string | – | – |
| url | string | – | – |
No output schema declared.
No examples provided.
document_propose_replacement Propose replacing one paragraph's text ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| paragraph_index | integer | yes | – |
| reason | string | – | – |
| text | string | yes | – |
No output schema declared.
No examples provided.
document_read Read paragraphs ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | – | – |
| from | integer | yes | – |
No output schema declared.
No examples provided.
document_save_copy Save a copy of the edited file ~99

A workbook with macros comes back as .xlsm with the VBA project intact; a document keeps its styles, comments and tracked changes.
| Name | Type | Req | Description |
|---|---|---|---|
| inline | boolean | – | also return the bytes as base64 (only for files up to 4 MB) |

| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | – |
No output schema declared.

No output schema declared.
No examples provided.
sheet_apply Apply proposed cell edits ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| proposal_id | string | yes | – |
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.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | – |
| sheet | string | – | 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.
| Name | Type | Req | Description |
|---|---|---|---|
| edits | array | yes | – |
| reason | string | – | – |
| sheet | string | – | – |
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.
| Name | Type | Req | Description |
|---|---|---|---|
| range | string | yes | – |
| sheet | string | – | 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.
