Connect Grok to Outlook on Mac
In short: Let Grok read, search, send and reply to email and check your calendar through the Microsoft Outlook app installed on your Mac — no Graph API.
Grok can work with Outlook on your Mac once LMCP is installed and added to Grok. LMCP is a local MCP server: Grok can read, search, send and reply to email and check your calendar through the Microsoft Outlook app installed on your Mac — no Graph API.
What Grok Can Do with Outlook
- Read your inbox and search emails by sender, subject, date, or content
- Send emails and reply to threads from your Outlook account
- Organize — move messages between folders, archive, or trash
- View your schedule and create events
Preview and confirmation behavior depends on the tool, platform and AI client. Check the tool requirements and review the intended action before authorizing a real call.
What You Will Need
- macOS 13+ and LMCP installed
- Microsoft Outlook for Mac (the desktop app)
- A Grok account — whether custom connectors (“Bring Your Own MCP”) are available depends on your Grok plan, which xAI sets
Connect Grok to Your Mac

Install LMCP on your Mac
Download LMCP from local-mcp.com and run the installer — it installs Local MCP to Applications and auto-configures your AI clients in ~30 seconds.

Turn on web access and copy your Connection URL
Click the LMCP icon in your menu bar and find Your web AI · Cloud Relay. Make sure web access is ON (it is on after installation unless you turned it off), then open your assistant’s panel and click Copy URL.
The URL is — it carries no token and is the same for everyone; every step below that says “the URL you copied” means this one. Access is granted by approving the connection on your Mac, not by the URL. - 3
Open Grok’s connectors
Go to grok.com/connectors, click New Connector, and choose Custom (Bring Your Own MCP).

Add the connector
Grok’s form has only Name and Server URL, and neither asks for a credential. Set Name: and Server URL: paste the URL you copied ( — it carries no token), then click Add. Add only registers the connector: approve the connection in the dialog that opens on your Mac, and the tool catalog loads after that. If no dialog appears, the approval simply expired — it lasts 5 minutes — so try again; nothing needs reinstalling.

Enable it in a chat
Start a new chat, enable the LMCP connector, and ask: “List my email accounts.” The connector URL never changes, so there is nothing to rotate or re-copy: what ties it to your Mac is the approval you gave, and you can revoke it by turning Cloud Data Forwarding off.
Steps verified 2026-09-17. Local tools run on your device; selected AI providers and connectors receive requested content. Review each tool’s permissions and approval behavior.
More detail: the full Grok guide.
Try It Out
Start a new chat, enable the LMCP connector, then ask:
Show me my unread emails in Outlook.
What meetings do I have tomorrow?
Summarize all emails from the sales team this week.
Troubleshooting
Outlook is installed but the assistant cannot access it
Check System Settings > Privacy & Security > Automation. LMCP needs permission to control Microsoft Outlook.
Can I use this with Outlook on the web?
No. LMCP connects to the native Outlook app installed on your Mac, not Outlook in a web browser.
Grok shows “0 tools” or only setup_install
Either the connection was never approved on your Mac — remove the connector and add it again to trigger a fresh approval — or Cloud Data Forwarding is OFF: toggle it ON in the Cloud Relay section.
Connector shows “Connected” but tools fail
Make sure LMCP is running (the menu bar dot should be green) and Cloud Data Forwarding is on. If the approval is no longer valid, remove the connector and add it again: the URL never changes, so there is nothing to copy again.
Custom connector option not available in Grok
Whether “Bring Your Own MCP” custom connectors appear depends on your Grok plan, which xAI sets. If you only see prebuilt connectors, use LMCP with a local client (Claude Desktop, Cursor, Claude Code) that connects directly without the Cloud Relay.
