Claude is asked to reply to a request through Ridian. Ridian reads the email in the Agent Mailbox, finds free time in Google, Microsoft and iCloud, and saves the reply with two suggested slots as a draft.
Assistants that connect to Ridian via MCP: Claude and Claude Code, ChatGPT and Codex, Cursor, OpenClaw, and other MCP clients with OAuth.
In ChatGPT, someone asks for a room for six on Thursday at 10 am and for prep tasks. Through Ridian, room Isar is booked and two tasks are created in Microsoft To Do.
Permissions per calendar: work read and write, team read only, personal free/busy only.
The access log lists Claude's actions with time, tool, and result. A delete attempt was rejected. No content is stored.

Agent Connect

Your assistant plans for you in your calendars.

  1. Give your assistant secure access

    Simply connect the assistants you already use, whether Claude, ChatGPT, Cursor, Codex or others, to your calendars and email.

  2. Meetings, rooms and tasks

    Your assistant finds free time for you, adds meetings, books rooms, creates tasks and plans your workday with you.

  3. You decide what it sees

    Ridian sits in between as your control layer: you decide exactly what your assistant may read and do and how much it sees, so you always stay in charge of your data.

  4. See what it did

    You see every step your assistant has taken, so you keep full control over what happens in your calendar.

Mail Connect

Your assistant takes care of your email.

  1. The inboxes you already have

    Your assistant gets secure access to your inboxes, whether at WEB.DE, GMX, iCloud or co., and writes email there for you.

  2. Email has never been easier

    Whether you have several accounts or different providers, your assistant works across all your inboxes, summarizes email, writes replies and creates tasks for you.

  3. You decide what goes out

    In the settings you decide whether your assistant only creates drafts or may also send. Ridian sits in between as your control layer, so you're always on the safe side.

  4. An inbox of its own for your agent

    With Agent Mailbox, your agent gets its own address on ridianmail.com and works for you as a truly independent agent, without needing your inbox.

Frequently asked questions

What's the difference between Agent Connect and Mail Connect?

Agent Connect links your assistant to Ridian over MCP, so it can work with your calendars, rooms and tasks. Mail Connect adds the inboxes you already have. Your assistant uses both through the same connection.

And what is Agent Mailbox?

Your agent's own inbox with an address on ridianmail.com, where the email is stored at Ridian. Mail Connect, by contrast, uses your existing inbox and keeps no copy. Either way, you decide for each inbox whether your assistant can access it.

Which assistants work with it?

Claude, ChatGPT, Cursor, Codex and Claude Code, and other clients that support MCP with OAuth can usually connect the same way. In Claude, you'll find Ridian in the connector directory.

Does Ridian read along with my events?

Your assistant gets only what you've allowed. For each calendar, you choose whether it sees only when you're busy, title and time, or every detail.

Which inboxes work?

There are presets for iCloud, Yahoo, AOL, WEB.DE, GMX and T-Online, and you set up others automatically or by hand. Connect Gmail and Outlook.com through Google or Microsoft sign-in instead. How many inboxes you can connect depends on your plan.

Does Ridian store my email?

Ridian keeps no copy of connected inboxes. Each request opens a connection, fetches what's needed and closes it again. Nothing is fetched in the background and nothing is marked as read.

Does Alvin ask before sending an email?

For Alvin, you decide whether he asks before sending or sends right away. External assistants like Claude follow their own confirmation rules.

How do I revoke access?

In the console under AI & Assistants, where you disconnect each assistant separately. On paid plans, you'll also find the access log there, kept for 7 or 90 days depending on your plan.

What does a tool call cost?

What MCP calls cost depends on the pricing model: you'll find the details on the pricing page. Calls that fail or get rejected are free, unless the outcome of a change is unclear.
