Time to complete: ~5 minutes
Requirements: Windows 10 or later, Node.js 18+, Claude Desktop or Cursor or VS Code


Step 1 — Install Node.js

If you don't have Node.js installed, download it from nodejs.org (LTS version recommended).

Verify it's installed by opening PowerShell and running:

node --version

You should see v18.x.x or higher.


Step 2 — Run the Installer

Open PowerShell and run:

npx -y local-mcp@latest setup

If you get a script execution error, run this first:

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned

The installer will:

  • Download the LMCP server binary for Windows
  • Detect your AI clients (Claude Desktop, Cursor, VS Code)
  • Write the MCP configuration automatically
  • Handle both Microsoft Store and standalone Claude Desktop installs

Step 3 — Restart Your AI Client

Close Claude Desktop completely (right-click the system tray icon → Quit, or Alt+F4) and reopen it.

You should see a hammer icon in the chat input area — click it to see the available tools.


Step 4 — Try Your First Tool Call

In Claude Desktop, try one of these prompts:

  • "List my recent Outlook emails"
  • "What files are in my OneDrive?"
  • "Create an Excel file with headers Name, Email, Phone"
  • "What's AAPL trading at?"

What's Available on Windows

LMCP for Windows includes 56 tools across these categories:

  • Outlook — read, send, reply, forward, search emails; manage calendar events; search contacts
  • OneDrive — browse, read, write, search, delete, move files
  • Office — read/create Word and Excel files, read PDFs and PowerPoint
  • Teams — read chats and channel messages (reads local cache, no API tokens)
  • Slack — list workspaces, channels, read and search messages
  • Explorer — list directories, search files
  • To Do — list, create, and complete tasks
  • Stocks — real-time quotes, charts, symbol search

Troubleshooting

Claude Desktop doesn't show the tools

If you installed Claude Desktop from the Microsoft Store, LMCP writes the config to a special path. Make sure you're running the latest version of the installer (npx -y local-mcp@latest setup).

Outlook tools return errors

Outlook tools require Microsoft Outlook desktop app to be installed and configured. They use COM automation — no API keys needed, but Outlook must be present on the machine.

Teams/Slack tools return empty

Teams and Slack tools read from the local desktop app cache. Make sure the desktop apps are installed and have been opened at least once.
