Connect Devin Desktop / Windsurf to Pear MCP

1. Create your Pear account

Sign up at pearmcp.com and connect Apple iCloud or Microsoft 365. Pear's documented Devin Desktop / Cascade uses an environment-backed API key in the remote-server header configuration below.

Apple Reminders compatibility

Apple Reminders availability depends on the Apple account. For Apple, Pear can read and write only the legacy reminder lists Apple still exposes through CalDAV. If the account has been upgraded to Apple's newer Reminders store, Pear cannot access those native lists and does not copy them into a separate reminder store. Apple may instead return compatibility placeholders, such as repeated "Where are my reminders?" items; Pear did not create them. Pear's safe fallback hides known placeholders and blocks writes to affected lists. Reconnecting iCloud or replacing the App-Specific Password will not change this Apple limitation. Calendar, Contacts, and Mail are unaffected, and Microsoft To Do uses Microsoft Graph and is unaffected. Full modern Apple Reminders access would require an Apple-platform companion using EventKit with the user's permission; Pear does not currently provide one.

2. Add Pear in Cascade MCP settings

Devin Desktop's Cascade MCP docs support the Marketplace, the Settings UI, and rawmcp_config.json. Legacy Windsurf installs retain the Windsurf configuration path. Add Pear as a remote HTTP server and refresh the server list. Enterprise users must enable MCP manually in settings. Team admins can disable MCP or restrict servers through registry and allowlist controls, so contact an admin if Pear is unavailable.

3. Use Pear from Cascade

• Ask Cascade to list MCP tools and confirm Pear is connected.
• Try “Am I free at 3pm today?” as the first read-only test.
• Use scheduling or task writes after confirming the provider; Apple writes require a usable legacy CalDAV reminder list.
• Keep Pear enabled only in workspaces that need productivity context.
