Proton Mail & Calendar MCP Server
Please add official MCP support for Proton Mail and Proton Calendar via remote streamable HTTP.
This is becoming essential for anyone who uses AI agents for serious personal or professional work. I need trusted agents—whether Claude Enterprise with strong contractual protections today, or hopefully Lumo through MCP in the future—to be able to securely see, manage, search, summarize, and draft emails and calendar events on my behalf.
For professionals and business customers, email and calendar are not side features. They are the operating system of work. If agents cannot access them, they cannot actually help with the workflows people pay for: preparing for meetings, tracking commitments, drafting replies, triaging inboxes, scheduling, following up, and coordinating across projects.
Proton is well positioned to do this the right way: privacy-preserving, user-authorized, auditable, revocable, and scoped. MCP is a natural fit because it allows Proton to expose controlled capabilities without forcing users into unsafe scraping, unofficial bridges, browser hacks, or full-account access through less trustworthy tools.
This is not just a power-user request. Business customers and professionals are increasingly going to expect their core productivity stack to work with agents. If Proton Mail and Calendar cannot participate in that ecosystem, Proton becomes harder to choose for serious work, even for people who strongly prefer Proton’s privacy model.
Please support Proton Mail and Calendar as official MCP servers using remote streamable HTTP, with granular permissions for reading, searching, labeling, drafting, sending, calendar lookup, event creation, and event updates.

One simple feature request
A "Pin to Top" capability for emails would a great feature. It would be similar to the Star feature, except any email pinned to the top would stay at the top of the list no matter how the inbox is sorted. That way it doesn't scroll off the bottom of the screen.

Meaningful subject line for appointment reminder emails
You can set up an email reminder for appointments in Proton Calendar.
When the email arrives, you unfortunately can't read what it's about in the subject line.
Example:
Reminder: Appointment starts on Sunday, October 5 (all day)Instead, the appointment title should appear after "Reminder:".

When an email is sent to a catch-all address, send the reply from the address used
When I receive an email to a catch-all address and reply, I then have to leave the email, go to settings and manually configure an identity to reply from the address they emailed.
There should be an option to make this the default behaviour when replying to such an email, without manual intervention.

(More) flexible start times on booking pages
When you create a booking page, you also set fixed time slots for the appointment. The user can select one of these and complete a booking. It would be great if there would be an option to leave the starttime selection up to the user of the booking page.
== Example of current situation ==
I make a booking page for an 1h-appointment. I create the following time slots
* 12:00 to 13:00
* 13:00 to 14:00
* 14:00 to 15:00== The problem ==
The users of the booking page can select any of these three options, but they are limited to these start and end times. But, as per these options, I am available from 12:00 until 15:00.== Example of prefered solution ==
I set the appointment for 1 hour, and I indicate I'm availabile from 12:00 until 15:00. The user can freely select the start time.== Alternative, more klunky solution ==
Allow for the overlap of timeslots. That way, we could make timeslots like
* 12:00 to 13:00
* 12:30 to 13:30
* 13:00 to 14:00
* 13:30 to 14:30
* 14:00 to 15:00
This is probably never granular enough, but it would at least alleviate the problemWhen you create a booking page, you also set fixed time slots for the appointment.

Support for multiple account in Proton Calendar

Add an option to disable automatic “Mark as read”
Please add a setting to Proton Mail’s desktop and web apps that allows users to choose when a message is marked as read:
Immediately when opened
After a configurable delay
Only when manually marked as read
I use Proton Mail Bridge with Thunderbird and have disabled Thunderbird’s automatic “Mark as read” behavior. Thunderbird correctly keeps opened messages unread, but opening one in Proton Mail immediately changes the shared read status and synchronizes that change back through Bridge.
A manual-only option would support workflows where “unread” means the message still requires attention. The existing automatic behavior could remain the default.

Protect Main E-Mail Address from leaking
Add an option in the settings to protect the main e-mail address from being leaked. When this option is turned on and I accidentily send an E-Mail which would reveal the default/main e-mail to the recipient the server would not send that e-mail and notify me that I need to use a reverse alias. Additionally, I think it would be nice to be able to select e-mails that differ from the main/default e-mail for protection, as some people might have multiple addresses they would want to protect from leaking.

Appointment scheduling feature in Proton Calendar - Calendly like features are missing
In my opinion, this isn't a 100% replacement for the functionality offered by Calendly or TidyCal.
For the person making the booking, there's only a name and email address field. With Calendly and TidyCal, I have informative forms that my clients can fill out before booking. I'm missing address details (street, city, postal code, phone number) as well as a subject for the booking, ideally with a predefined selection that the client can choose and above all a text field.
Furthermore, my main Proton email address is displayed below the organizer in the booking field. Since I use my own domain address, which is associated with my practice, I should be able to choose what is displayed, as I don't want my private Proton address to appear there. Ideally, I would prefer that no email address be displayed at all.
Besides a link to the booking page, an embed code for websites would also be great.
It would be nice if these things could be improved.

Notifications for Shared Calendar Event Changes
Dear Proton Team,
I'm writing to request a new feature for Proton Calendar that would greatly improve the shared calendar experience.
Current Situation: When events are added or modified on a shared calendar by another user, there is currently no notification sent to other calendar participants.
Requested Feature: Please implement real-time notifications (similar to Apple Calendar) when someone adds, modifies, or deletes an event on a shared calendar. This would allow users to:
Stay informed about changes made by family members or colleagues
React promptly to schedule updates
Better coordinate shared schedules without constantly checking the calendar manually
Use Case: As someone who switched from Apple to Proton, this is a feature I genuinely miss. For example, when my spouse adds an event to our shared family calendar, I would like to receive an immediate notification so I can see it right away rather than discovering it later during manual checks.Why This Matters: This functionality is essential for effective collaboration on shared calendars and would significantly improve the user experience for families, teams, and anyone managing shared schedules.
Thank you for considering this enhancement. Proton's privacy-focused approach is excellent, and adding this quality-of-life feature would make Proton Calendar even more competitive.
Best regards

Feature Request – More Flexible Calendar Views & Year Overview
Dear Proton Team,
I’m writing to suggest an enhancement that would make the calendar experience even more enjoyable for users like me. It would be great if the interface allowed more flexible view options (e.g., customizable week ranges, adjustable column widths, and easy toggling between compact and expanded layouts).
Additionally, adding a dedicated “Year” view—showing all twelve months at once—would help users get a quick, high‑level perspective of their schedules and plan ahead more efficiently.
These improvements would boost productivity, reduce the need to switch between multiple tools, and align Proton Calendar with the flexibility offered by many competing calendar apps—all while preserving the privacy‑first ethos we love.
Thank you for considering this request!
Kind regards

Tasks in Proton Calendar
The Idea
I would love to see Proton Calendar evolve into a unified productivity hub by integrating a native task and project management layer — think the best of Microsoft To Do and Microsoft Planner, but built with the privacy-first DNA that makes Proton what it is.
What I Am Proposing
A task management module embedded directly inside Proton Calendar that allows users to:
Create and assign tasks with due dates, priorities, and labels — visible alongside calendar events in a single, unified view.
Organise tasks into project boards — simple Kanban-style columns (To Do / In Progress / Done) for teams or personal workflows.
Track deadlines and milestones without leaving the calendar environment — no more context-switching between three different tools.
Set recurring tasks and receive reminders that align with existing calendar notifications.
Share task boards with collaborators within the Proton ecosystem, with granular permission controls.
Why This Matters
Right now, managing deadlines across tools is fragmented. Calendar events live in one place, tasks in another, and project milestones in yet another. For professionals managing complex, deadline-driven workflows — such as regulatory compliance cycles, multi-party projects, or recurring reporting obligations — this fragmentation creates real risk: missed deadlines, duplicated effort, and unnecessary context-switching.
Proton already owns the calendar real estate. Tasks are the natural next layer. The combination would make Proton Calendar a serious, privacy-respecting alternative to the Microsoft 365 productivity stack — without surrendering data to advertising-driven ecosystems.

The Ask
This does not need to be a full project management suite on day one. A phased rollout could work well:
Phase 1: Personal tasks with due dates, visible in calendar view.
Phase 2: Task lists / labels and recurring task support.
Phase 3: Shared boards and milestone tracking for teams.
Final Thought
Proton has already proven that privacy and productivity are not mutually exclusive. Adding a robust task layer to Proton Calendar would be the next logical step in making the full switch away from Big Tech ecosystems a realistic option for professionals and organisations that care about where their data lives.
Would love to hear whether others in the community share this need — and whether the Proton team has any plans in this direction.

Proton Duo with shared email inbox
It would be nice if the members of a Duo had a shared email address and inbox. Most couples need at times to communicate jointly together as a couple, either socially or for household business.
It would be even better if a Duo also included a full joint account with all features so that there is equality in the way information is shared and used.

Turn the self-promoting with the flashy 'Special offer' down a few notches
I think i might speak for the majority of paying customers: We pay good money to be spared from promotions/advertising and now exactly that is sneaking in through the back door - a flashy, gaudy promotion button and inside the UI of all places! And not even smart enough to hide itself even after I clicked on it! No context menu either that would allow me to hide that 'thing'.... Please do better and live up to your own advertising promises!
