Common questions

Is Excel 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 (0.1.2) 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 Python (uv) on your computer.

What can I use instead?

Let your AI agent read real, messy Excel files. An MCP server that handles the things LLMs choke on: multiple sheets, title rows sitting above the actual table, and merged cells.

If you paste a spreadsheet into a prompt, the model has to guess where the data starts and what the merged cells mean, and it often gets it wrong. This reads the file properly with deterministic code, so the values are exact and the model never invents cell contents.

The problem it solves

A real spreadsheet almost never starts cleanly at cell A1:

A1:  Quarterly Sales Report 2024      <- title, not data

A2: Generated by finance <- note, not data A3: (blank) A4: Region | Product | Units <- the actual header A5: North | Widget | 120 ...

Ask an LLM to read that and it'll often treat the title as a column. read_table auto-detects that the header is on row 4 and returns clean records. Merged cells (a value spanning several rows) get forward-filled, so rows don't lose their category.

The tools it gives an agent

Tool	What it does
`list_sheets(path)`	Every sheet in the workbook, with its size
`preview_sheet(path, sheet, rows)`	Top rows as a grid, so the agent can see the layout
`read_table(path, sheet)`	The actual data table as records. Reports the decisions that could be wrong: `header_source` (explicit / auto-detected), `header_confidence`, and `forward_filled_columns` (values inferred from merged cells, not read)
`sheet_to_csv(path, sheet)`	The table as clean CSV text

Getting started (Claude Desktop)

The fastest way to use this is with an MCP client like Claude Desktop. Three steps:

1. Install it

pip install "excel-agent-mcp[mcp]"

2. Add it to your client's config

Claude Desktop's config lives here:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Add the server:

"mcpServers": { "excel": { "command": "excel-agent-mcp" } } }

3. Restart Claude Desktop. You'll see a tools icon appear, meaning the server is connected.

That's it. Now ask about any .xlsx file on your machine:

You:  What's in /Users/me/reports/sales.xlsx?

Agent (calls list_sheets, then read_table): The workbook has one sheet, "Q1". The table starts on row 4 (the rows above are a title). 3 rows: North/Widget/2400, South/Widget/3000, South/Gadget/2400. Total revenue 7800.

The agent reads the real file instead of guessing, so the numbers are exact.

Restricting file access: to stop the agent reading anything outside one folder, set

EXCEL_MCP_ALLOWED_DIR. See SECURITY.md.

Use it with other MCP clients

The same server works in any MCP client, only the config differs. Use excel-agent-mcp as the command.

Cursor — ~/.cursor/mcp.json (global) or .cursor/mcp.json (per project). Same shape as Claude Desktop, and it hot-reloads (no restart):

{ "mcpServers": { "excel": { "command": "excel-agent-mcp" } } }

VS Code / GitHub Copilot — .vscode/mcp.json. Note the different key (servers, not mcpServers) and the required type. Tools only run in Copilot Agent mode:

{ "servers": { "excel": { "type": "stdio", "command": "excel-agent-mcp" } } }

Windsurf — ~/.codeium/windsurf/mcp_config.json (create it if missing). Same shape as Claude Desktop:

{ "mcpServers": { "excel": { "command": "excel-agent-mcp" } } }

Cline — add it from the extension's MCP settings panel in VS Code (command: excel-agent-mcp).

Understanding the output

read_table doesn't just return the data, it tells you how confident it is, so you can trust a clean parse and double-check a guess:

"columns": ["Region", "Product", "Revenue"], "rows": [ ... ], "header_row": 3, "header_source": "auto-detected", "header_confidence": 0.42, "forward_filled_columns": ["Region"] }

`header_source` — "explicit" if you told it which row is the header, "auto-detected" if it guessed.
`header_confidence` — 0..1 for an auto-detected header. A low value means it was a close call; if the result looks off, pass an explicit header_row.
`looks_clean` + `table_warnings` — a verdict on the table as a whole (flags low header confidence, unnamed columns, mostly-empty tables), separate from the per-column signals below.
`forward_filled_columns` — columns whose values came from a merged cell. Those values are *inferred* (copied down to fill the block), not read cell-by-cell, so treat them accordingly.

The idea: surface the decisions that could be wrong, instead of handing back tidy-looking output that hides a guess.

Also usable from plain Python

from excel_mcp import reader

reader.list_sheets("report.xlsx") reader.read_table("report.xlsx", "Sales") # {'columns': [...], 'header_source': ..., ...} reader.sheet_to_csv("report.xlsx", "Sales")

Tests

python -m unittest discover -s tests     # builds its own messy xlsx, runs anywhere
