Windsurf MCP Setup on Mac
Give Windsurf's Cascade agent direct access to your Mac apps — Mail, Calendar, Contacts, iMessage, Teams, Slack and 233 tools. LMCP writes the Windsurf MCP configuration automatically when you install it.

Windsurf supports MCP servers in Cascade, so the agent can call tools that run on your Mac. LMCP provides them locally — no API keys, no OAuth — so from Cascade you can ask:
- “Summarize the emails about this project and add follow-ups to Reminders”
- “What did the team say in Slack about the release?”
- “Schedule a review with Marco on Thursday afternoon”
Setup
- Download LMCP and run the installer — it detects Windsurf and writes the MCP entry automatically.
- In Windsurf, open Cascade and confirm MCP is enabled (Settings → Cascade → MCP).
- Ask Cascade anything about your Mail, Calendar or Teams. macOS prompts for each permission the first time it’s needed.
Privacy
Windsurf talks to LMCP over a local socket on your Mac. Your data is read on-device and never uploaded; anything the agent wants to send is preview-and-confirm.
