How to Set Up and Use Outlook Calendar MCP
Outlook Calendar MCP is a Windows-only MCP server that gives Claude direct access to your local Microsoft Outlook desktop calendar, keeping all data on your machine with no cloud sync required. It exposes tools for listing events by date range, creating new meetings with attendees, updating existing events, and finding free time slots across multiple calendars. Users who rely on the Outlook desktop client for scheduling can let Claude draft meetings, check availability, and manage their calendar through natural conversation.
Prerequisites
- Windows operating system (this server does not run on macOS or Linux)
- Microsoft Outlook desktop client installed and configured with at least one calendar
- Node.js version 14.x or higher and npm
- VBScript enabled — on Windows 11 24H2+, install it via Settings > Apps > Optional features > Add an optional feature > VBScript
- An MCP-compatible client such as Claude Desktop
Install the package via npm
Install the outlook-calendar-mcp package globally or use npx to run it without installation.
npm install -g outlook-calendar-mcp
# Or use npx directly (no prior install needed):
npx outlook-calendar-mcpCheck VBScript availability (Windows 11 24H2+)
On recent Windows 11 builds, VBScript must be enabled manually as an optional feature. Open Settings > Apps > Optional features > View features, search for VBScript, install it, and restart.
Configure Claude Desktop
Edit %APPDATA%\Claude\claude_desktop_config.json on Windows. Use the npx form for the simplest setup — no global install required.
{
"mcpServers": {
"outlook-calendar": {
"command": "npx",
"args": ["-y", "outlook-calendar-mcp"],
"env": {}
}
}
}Alternatively, use the global install command
If you installed globally via npm, reference the binary directly for faster startup.
{
"mcpServers": {
"outlook-calendar": {
"command": "outlook-calendar-mcp",
"args": [],
"env": {}
}
}
}Restart Claude Desktop and verify
Restart Claude Desktop. Ask Claude to list your calendar events for today to verify the connection to Outlook is working.
Outlook Calendar MCP Examples
Client configuration (Claude Desktop on Windows)
Standard Windows configuration using npx. No API keys or environment variables are required — the server communicates with the local Outlook COM object via VBScript.
{
"mcpServers": {
"outlook-calendar": {
"command": "npx",
"args": ["-y", "outlook-calendar-mcp"],
"env": {}
}
}
}Prompts to try
Use these prompts to manage your Outlook calendar through Claude.
- "List my calendar events for next week."
- "Schedule a 1-hour team standup on Friday at 10 AM and invite [email protected] and [email protected]."
- "Find a 30-minute free slot this afternoon between 2 PM and 5 PM."
- "Update tomorrow's project review meeting to start at 3 PM instead of 2 PM."
- "Show me all meetings on my Work calendar for the next 7 days."
- "What events do I have on 06/20/2026?"Troubleshooting Outlook Calendar MCP
The server starts but cannot access Outlook or returns 'Outlook not found'
Ensure Microsoft Outlook desktop client (not the web version) is installed and has been opened at least once to complete its initial setup. The server uses COM automation, which requires the full desktop client.
VBScript errors appear after a Windows 11 update
Starting with Windows 11 24H2, VBScript is not installed by default. Go to Settings > Apps > Optional features > Add an optional feature, search for 'VBScript', install it, and restart your computer.
Events created by Claude do not appear in Outlook
Ensure Outlook is running when Claude attempts to create events — the COM automation requires an active Outlook process. If Outlook is open and events still do not appear, check that the calendar specified (if any) matches an existing calendar name in your Outlook profile.
