Independent review. IonBin has no partnership with Proton and was not paid for this page. Our evaluation is our own, based on public documentation and our research. Product names are trademarks of their owners and are used for identification only. How disclosure works.
Encrypted mail, calendar, drive, password manager and VPN. No official MCP server or public REST API; Proton Pass offers AI access tokens that give an agent only the credentials you share, and logs each request.
Billed every 12 months, Workspace Standard is $12.99 per user/month ($155.88/year; 1 TB per user, mail, drive, VPN, Pass) and Workspace Premium $19.99 ($239.88/year; 3 TB, the Lumo AI chat). Taxes may apply; 14-day trial. Checked 2026-10-17. source ↗
How Proton connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.
| Platform | MCP / connector | API (agent-written code) | Browser | Upload / export |
|---|---|---|---|---|
| Claude (incl. Claude Code) | No documented route | No documented route | Confirmed Claude Code with the Claude in Chrome extension (Chrome, Edge and other Chromium browsers) Claude (incl. Claude Code) browser docs ↗ | Confirmed Export from Proton, then works on the files in your project; chat accepts attachments Claude (incl. Claude Code) docs ↗ |
| OpenAI Codex | No documented route | No documented route | Confirmed Only in the ChatGPT desktop app; not in the Codex CLI or IDE extension OpenAI Codex browser docs ↗ | Confirmed Export from Proton, then works on local repositories OpenAI Codex docs ↗ |
| Google Antigravity | No documented route | No documented route | Confirmed Browser subagent via /browser, documented as an Antigravity App feature; the IDE has separate browser docs Google Antigravity browser docs ↗ | Confirmed Export from Proton, then works on local projects and worktrees Google Antigravity docs ↗ |
Confirmed means both the tool's and the platform's official docs describe that route (links in the cell); IonBin has not tested every pairing. Not documented means it may work, but no official docs describe that route end to end. Checked Oct 17, 2026.
| Level | Status | Detail / source |
|---|---|---|
| Native connector / MCP | No | No official MCP server found (2026-10-17); community servers only |
| API / CLI | No | No public REST API; Proton Pass AI access tokens share chosen credentials with agents (https://proton.me/blog/pass-access-tokens) |
| Browser-only | Yes | No confirmed MCP server or API yet |
| Bulk upload / import | Yes | Easy Switch migrates mail, contacts and calendars from Google Workspace or Microsoft 365 (https://proton.me/support/easy-switch-for-business) |
Recorded Oct 17, 2026. Setup and plan limits vary; check the vendor's docs. How levels are assigned.
No confirmed MCP server yet.
No long-form review yet. Verdict is based on research, not hands-on testing.
Password manager and secrets platform. Its Environments MCP server runs locally in the 1Password desktop app and lets coding agents such as Claude Code and Cursor work with environment variables; by design it cannot return secret values to the agent.
Business password manager for shared logins. NordPass Enterprise offers an Activity Logs API that Owners and Admins can query; no official MCP server found.
