Secure Calendar (google Calendar And Outlook) Mcp Server
Secure Calendar is a remote MCP server that gives AI assistants controlled access to your Google Calendar and Outlook (Microsoft 365) calendars. Connect it to Claude, ChatGPT, or any MCP client and let the AI find open slots, book and move meetings, cancel events, and RSVP, while PortEden, the data firewall for AI, keeps you in control of your schedule and your data.
Unlike a raw "Google Calendar MCP" token, Secure Calendar limits the AI to the exact permissions you grant, protects sensitive event details, logs every change, and lets you revoke access in one click.
Why Secure Calendar
- Scoped permissions. The AI only does what you allow, per user, per AI, per project, and cannot exceed that ceiling.
- Sensitive details protected. PortEden redacts sensitive data before it reaches the AI.
- One-click revoke. Cut access instantly, effective on the very next request.
- Full audit trail. Every create, update, and delete is logged.
- Nothing stored. No tokens, no cache, no database in the connector.
What you can do
- Check availability: "Find a free 30-minute slot with Alex this week."
- Search your schedule: "What meetings do I have with the design team next week?"
- Create events: "Create a focus-time block Friday morning."
- Reschedule and update: "Move my 2pm to 4pm and add a video link."
- Cancel: "Cancel my Thursday standup."
- RSVP: "RSVP yes to the design review."

Getting started
- Create a free PortEden account at https://porteden.com.

pe_mcp_) and paste it into the config above as your Bearer token.
Prefer OAuth 2.0? Add the URL https://mcp.porteden.com/calendar to your client with no token and sign in. For a client that needs a stdio bridge, use mcp-remote:
{
"mcpServers": {
"secure-calendar": {
"command": "npx",
"args": ["-y", "mcp-remote", "https://mcp.porteden.com/calendar"]
}
}
}
Works with
Claude (Desktop, web, and Code), ChatGPT, Microsoft Copilot, Google Gemini, Grok, and Cursor, plus any client that speaks MCP Streamable HTTP. Authentication: paste a PortEden access key (a pe_mcp_ Bearer token), or connect over OAuth 2.0 (OAuth 2.1 with RFC 9728 protected-resource metadata and dynamic client registration).
FAQ
Can the AI book meetings on my behalf? Yes, within the permissions you grant. You can scope it to read-only or allow create, update, and delete.
Does it see private event details? Only what your permissions allow, after redaction of sensitive data.
Where is my data stored? Nowhere in the connector. It is stateless. PortEden enforces permissions, quotas, redaction, and audit logging.
Your data. Your rules. More info: https://porteden.com/
