Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "xlsx-audit": {
      "command": "npx",
      "args": [
        "-y",
        "xlsx-audit-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add xlsx-audit -- npx -y xlsx-audit-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "xlsx-audit": {
      "command": "npx",
      "args": [
        "-y",
        "xlsx-audit-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "xlsx-audit": {
      "type": "stdio",
      "command": "npx",
      "args": [

Common questions

Is Xlsx Audit MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

xlsx-audit-mcp

An MCP server that audits Excel workbooks. Other Excel MCP servers read and write your data — this one reviews your *model*:

*"What feeds the Total cell on the Summary sheet?"* — precedent tracing
*"If I change this assumption, what breaks?"* — dependent tracing, including cells that consume it through ranges like SUM(A1:A40)
*"Audit this workbook"* — circular references with example chains, volatile functions (INDIRECT, OFFSET, NOW, RAND...), hardcoded constants buried inside formulas, external workbook links, merged cells, extra-long formulas

Spreadsheet mistakes are famously expensive. This is the "trace precedents" discipline auditors apply by hand, exposed to an LLM for a whole workbook at once. Local files only; nothing leaves your machine.

Quick start

Claude Code

claude mcp add xlsx-audit -- npx -y xlsx-audit-mcp

Claude Desktop — add to claude_desktop_config.json:

"mcpServers": { "xlsx-audit": { "command": "npx", "args": ["-y", "xlsx-audit-mcp"] } } }

Then: *"Audit C:\\models\\budget-2026.xlsx and tell me what looks fragile."*

Tools

Tool	What it does
`workbook_overview`	Sheets, dimensions, formula counts, defined names, external links
`list_formulas`	Formulas with addresses and cached values, filterable (`INDIRECT`, `VLOOKUP`, ...)
`trace_cell`	One cell's formula, value, precedents, and dependents (direct + via ranges)
`audit_workbook`	Ranked risk report across the whole model

How it works

Reference tokenizer that understands real formulas: string literals are stripped first (the "A1" in INDIRECT("A1") is not a reference), function names can't collide (the G10 in LOG10(...) is not a cell), $ absolutes, quoted sheet names ('My Data'!A1), and ranges are handled.
Shared formulas are materialized. Excel stores filled formulas once with an offset scheme; the loader translates them per-cell (relative refs shifted, absolutes preserved), so dependency queries see what each cell actually computes.
Ranges are never expanded for storage — dependents queries use range-containment tests, and cycle detection caps range fan-out (a SUM(A:A) can't explode the graph; capped ranges are reported, not silently dropped).
No formula evaluation. Cached values from the file are shown instead — no spreadsheet engine dependency.

Known limitations: R1C1 notation and structured table references ([@Column]) are counted but not resolved into the graph.

Development

npm install

npm test # offline tests — synthetic workbooks built in-suite npm run build # tsc → dist/ node scripts/smoke.mjs # end-to-end: generates a workbook, drives the server over stdio

Architecture: src/xlsx.ts (zip + XML → workbook model) and src/formulas.ts (tokenizer, graph, smells) are pure logic; src/index.ts is the MCP wiring.
