First indexed and scored.

## MCP tools (21)

### `document_open` (~104 tokens)

Open a demo document or workbook

Open one of the demo files by name: documents footnotes, comments, forms, rtl, wild-horse, workshop, offer; workbooks workbook, functions, macros, queries, gep, vba-web, sqlite, order-desk, onrr, cashflow, pivot, chart, notes, check, xtools. Default is footnotes. For your own file use document_open_file. Opens a separate editor cabin for this session.

Input parameters:

- `slug` (string, required)

### `document_open_file` (~192 tokens)

Open your own Word document or Excel workbook

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). 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.

Input parameters:

- `base64` (string)
- `name` (string)
- `path` (string)
- `url` (string)

### `document_describe` (~36 tokens)

What the document is

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

### `document_read` (~73 tokens)

Read paragraphs

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.

Input parameters:

- `count` (integer)
- `from` (integer, required)

### `document_find` (~31 tokens)

Find in the document

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

Input parameters:

- `query` (string, required)

### `document_comments` (~27 tokens)

Comments and tracked changes

Comments (author, text, anchor, resolved) and tracked changes — up to 50.

### `document_propose_replacement` (~91 tokens)

Propose replacing one paragraph's text

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.

Input parameters:

- `paragraph_index` (integer, required)
- `reason` (string)
- `text` (string, required)

### `document_apply` (~68 tokens)

Apply a proposed paragraph replacement

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.

Input parameters:

- `proposal_id` (string, required)

### `sheet_describe` (~57 tokens)

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.

### `sheet_read` (~124 tokens)

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.

Input parameters:

- `range` (string, required)
- `sheet` (string): Exact tab name, e.g. "Logical". Required when the workbook has more than one sheet.

### `sheet_find` (~89 tokens)

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.

Input parameters:

- `query` (string, required)
- `sheet` (string): Exact tab name. Required when the workbook has more than one sheet.

### `macro_list` (~30 tokens)

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

### `macro_read_source` (~45 tokens)

Read the source text of one procedure (module + procedure name from macro_list). Read-only; runs nothing.

Input parameters:

- `module` (string, required)
- `procedure` (string, required)

### `macro_plan` (~51 tokens)

Plan a macro run without running it: route, whether the engine can run it natively, blockers, instruction budget.

Input parameters:

- `active_sheet` (string)
- `entrypoint` (string, required): Module.Procedure

### `query_list` (~33 tokens)

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

### `query_explain` (~43 tokens)

Explain one Power Query query by name: its steps in order, where it loads, its connection. Reads only; refreshes nothing.

Input parameters:

- `name` (string, required)

### `workbook_inspect` (~102 tokens)

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'.

### `sheet_propose_edits` (~114 tokens)

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.

Input parameters:

- `edits` (array, required)
- `reason` (string)
- `sheet` (string)

### `sheet_apply` (~71 tokens)

Apply proposed cell edits

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.

Input parameters:

- `proposal_id` (string, required)

### `document_save_copy` (~99 tokens)

Save a copy of the edited file

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.

Input parameters:

- `inline` (boolean): also return the bytes as base64 (only for files up to 4 MB)

### `document_export_pdf` (~59 tokens)

Render the document to PDF

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.
