What You Can Do — Calendrz MCP Server

❌ Other calendar MCP connectors

📅

Single account only

Connected to one Google or Microsoft account. If you have a work calendar and a personal one, you have to query them separately — or not at all.

🔍

Incomplete availability picture

Your AI only sees part of your schedule. It can't tell you if you're actually free — because it can't see your other calendars.

🔄

No cross-calendar awareness

Availability conflicts between accounts are invisible. Your AI assistant can't protect your time across all your calendars at once.

✅ Calendrz MCP

📅

All connected accounts, at once

One query returns events across every calendar account in your Calendrz profile — work, personal, side projects, all of them.

🪞

Full availability picture

Your AI sees your true availability — not just one slice of it. It knows when you're genuinely free across your entire schedule.

⚡

Trigger mirroring from conversation

Ask your AI to sync now and Calendrz auto-blocks your busy time across every connected account — instantly, without opening the app.

All of them.

Not just one. Every connected account, every calendar, in a single query.

"Show me my events across all my calendars for next week."

One prompt. Claude or ChatGPT queries your entire Calendrz profile — work, personal, freelance, side project — and returns a unified view of your week. No other calendar MCP connector can do this.

Works with your booking tools

Calendly and Google booking pages finally see your real availability.

Booking tools like Calendly and Google Calendar appointment pages only look at one calendar account to determine when you're free. If your busy time lives across multiple accounts, they can't see it — and double bookings happen.

😤 The problem without Calendrz

📅

Calendly only checks one account

You're in a meeting on your work calendar — but your personal calendar shows free. Calendly offers that slot to someone. Double booked.

🔧

You resort to hacks

Manually copying events between accounts. Creating dummy blockers. Paying for Calendly's multi-calendar feature. None of it is reliable and all of it is manual.

😬

Embarrassing conflicts

Clients book time you're not actually free. You have to reschedule. It looks unprofessional and erodes trust.

✅ With Calendrz availability mirroring

🪞

Busy time is auto-blocked everywhere

When you have a meeting on any connected account, Calendrz instantly auto-blocks that time on all your other accounts. Calendly always sees accurate availability.

⚡

No hacks. No manual work. Ever.

Set up Calendrz once and forget it. Every booking tool that checks any of your connected accounts will see your true, up-to-date availability — automatically.

✓

Zero double bookings

Whether someone books via Calendly, Google Calendar appointment pages, or any other scheduling link — if you're busy, it shows. Across all accounts, all the time.

Calendrz doesn't integrate with these tools directly — it works at the calendar layer, so every tool that reads your calendar automatically benefits.

Example prompts

Just ask. Calendrz handles the rest.

These are real things you can say to Claude or ChatGPT once Calendrz is connected.

Calendar access

"Show me my calendar events for next week."

Your AI reads directly from all connected accounts and returns a clean summary of your upcoming schedule.

Availability mirroring

"Are my calendars being mirrored right now?"

Instantly see which connected accounts have auto-blocking active and your current mirroring preferences.

Instant sync

"Sync my calendars now."

Triggers an immediate availability mirror across all connected accounts — no need to open the Calendrz app.

Preferences

"Enable importing tentative events."

Updates your mirror preferences so maybe/tentative events are also auto-blocked across your other calendars.

Profile

"What calendars do I have connected?"

Returns your full Calendrz profile — all connected accounts, their status, and your current subscription tier.

Subscription

"What subscription plans does Calendrz offer?"

Your AI fetches the current available tiers and features directly from Calendrz in real time.

The difference

Without Calendrz MCP vs. with it.

❌ Without Calendrz MCP

😤 You have to open Calendrz manually to check if mirroring is active
😤 Triggering a sync means navigating the app
😤 Updating mirror preferences requires logging in
😤 Your AI assistant has no awareness of your calendar availability
😤 Switching between tools breaks your flow

✅ With Calendrz MCP

✓ Ask Claude or ChatGPT to check your mirroring status instantly
✓ Say "sync now" from anywhere — no app switch needed
✓ Update preferences in natural language during any conversation
✓ Your AI knows your real-time availability across all calendars
✓ Calendrz works silently alongside your AI workflow

Use cases

Built for how you actually work.

Whether you're a consultant, freelancer, or PM juggling multiple calendars — here's where the Calendrz MCP shines.

💼

Consultants & freelancers

You have a work calendar, a client calendar, and a personal one. Ask your AI to confirm your availability is mirrored before sending a proposal — without leaving your email client.

"Make sure my calendars are synced before I send this proposal."

🧑‍💼

Product managers

Back-to-back meetings across work and side-project calendars. Let your AI check what's blocked and where gaps exist — in real time, in the middle of planning.

"Do I have any free slots tomorrow across all my calendars?"

🛠

Developers & builders

Build AI workflows that are calendar-aware. With the Calendrz MCP server, your agents can query availability, trigger syncs, and update preferences programmatically.

"Check if availability mirroring is active and sync if not."

📋

Executive assistants

Managing calendars for someone else? The MCP gives your AI assistant live awareness of which accounts are connected and whether auto-blocking is running correctly.

"Which of the connected accounts has mirroring disabled?"
