Microsoft Office MCP server: read and edit Word documents, Excel workbooks, and PowerPoint files
Today is the operative word: we check Microsoft Office every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
claude mcp add mcp-server-office -- npx -y @mindstone/mcp-server-office
{
"mcpServers": {
"mcp-server-office": {
"args": [
"-y",
"@mindstone/mcp-server-office"
],
"command": "npx"
}
}
}
[mcp_servers.mcp-server-office]
command = "npx"
args = ["-y", "@mindstone/mcp-server-office"]

This one needs environment variables set before it will start:
MCP_OFFICE_SIDECAR_STATE (Absolute path to sidecar state file (host-managed; sidecar writes port + token here)), MCP_OFFICE_SIDECAR_DISABLE (Kill-switch — set to 1 to refuse to spawn or talk to the sidecar), REBEL_DISABLE_OFFICE_SIDECAR (DEPRECATED legacy alias for MCP_OFFICE_SIDECAR_DISABLE — still honored for backward compatibility with v0.1.1 operator-set kill-switches; will be removed in a future major version. Use MCP_OFFICE_SIDECAR_DISABLE instead.), MCP_OFFICE_SIDECAR_STATE_DIR (Sidecar state directory (certs, per-app manifests). Normally derived from MCP_OFFICE_SIDECAR_STATE; hosts managing the sidecar lifecycle directly can override.), MCP_OFFICE_ADDIN_DIR (Absolute path to the built add-in static files. Defaults to the package's dist/addin/ directory.).
The author declared them in the registry entry; get the values from the project itself.
