Office Live MCP connects AI agents (Claude, Cursor, Codex, ZCode and other MCP clients) to Microsoft Excel and Word
that are already open on this computer. Changes appear on screen immediately while you keep working next to the agent:
reading and writing ranges, formulas, formatting, tables, charts, pivot tables, Word documents, tables and comments,
with a journal and undo of the agent's changes. Requires desktop Excel and/or Word (Microsoft 365 / Office 2016+).
A silent install does not connect any agent; use Start > Office Live MCP > Connect to agents, or install
interactively (winget install -i) to choose agents in the wizard.
Your AI agent. Your open Excel and Word. Less manual work.
Turn spreadsheet rows into Word/PDF documents, compare registers and review Word edits —
from the agent you already use, in the files you already have open.
130 tools for Excel, Word and document workflows - formulas, data cleanup, goal seek, pivots, charts, templates,
comment threads and more. Full catalog →
For compact responses, searches, comparisons, issue reports, formula traces and Word outlines return at most one
officelive:// link for the whole result; request per_match_links=true for individual locations.
excel_write_range keeps its existing read-back by default. Use readback="summary" for shape, counts, errors and
up to five sample cells, or readback="none" to omit value echoes. Undo and journaling work as before.
Lay out a sheet in two calls, each with one office_undo entry:
excel_set_dimensions(..., cells="", autofit="columns") fits only the used range.
Autofit rejects ranges above 100,000 cells or 1,000 affected dimensions and checks a
5-second budget between small COM calls, returning a clear error with undo for partial
changes. A synchronous Excel COM call cannot be interrupted while it is running.
Install
> Requirements: Windows 10/11 (64-bit) and desktop Excel and/or Word.
Download the installer (…-setup.exe) from the latest release.
Run it: Next → Next → Finish. On a fresh install, detected agents are preselected; choose full or read-only access.
Restart your agent and ask: “show me which workbooks are open in Excel”.
Update: run the new setup.exe over the old one, or in PowerShell (agents closed):
& ([scriptblock]::Create((irm https://raw.githubusercontent.com/mikhalchankasm/office-live-mcp/main/scripts/update.ps1)))
— scripts/update.ps1 installs the latest release silently. Uninstall: Settings → Apps → Office Live MCP.
Data and costs: the server runs locally, without an Office add-in; what your agent reads goes to its model provider,
and the agent and model are billed under that provider's terms.
