Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • calendar

    Show the Proton Calendar agenda for the next N days.

  • contacts

    List Proton contacts (name and email), optionally filtered by a query.

  • drive_download

    Download and decrypt a Proton Drive file to a local directory.

  • drive_list

    List a Proton Drive folder by path (folders first); empty path is the root.

  • drive_mkdir

    Create a new Proton Drive folder (empty parent_folder is the root).

  • drive_move

    Move a Proton Drive file or folder into another folder (empty dest_folder is the root).

  • drive_rename

    Rename a Proton Drive file or folder in place.

  • drive_share_link

    Create a public share link for a Proton Drive file or folder. The returned URL is the whole secret (its fragment holds the password) and lets anyone open the file, so only share it when the person asked to make this file public.

  • drive_trash

    Move a Proton Drive file or folder to the trash (recoverable in Proton Drive).

  • drive_unshare_link

    Revoke a Proton Drive file or folder's public share link.

  • drive_upload

    Encrypt and upload a local file into a Proton Drive folder (empty dest_folder is the root).

  • email_allow

    Set the recipient allowlist for send_message. Pass specific addresses or globs (e.g. *@company.com) to restrict sending to them, ["*"] to allow anyone, or [] to block all sending. A hard ceiling from PROTON_ALLOWED_RECIPIENTS still applies on top and cannot be loosened here.

  • email_policy_status

    Show the send policy: which recipients the allowlist permits (or that it is open), any hard ceiling set by the PROTON_ALLOWED_RECIPIENTS env var, and whether a send needs confirmation.

  • list_messages

    List messages in a Proton Mail folder (inbox, sent, archive, spam, trash, starred...).

  • read_message

    Read one Proton Mail message by id, decrypted, with HTML flattened to prose.

Show 3 more tools
  • search_messages

    Find messages whose sender or subject contains the query.

  • send_message

    Send an email. Plain text by default; set html=true to send the body as HTML. attachments is a list of local file paths to attach, e.g. a file you just fetched with drive_download. A send is refused if a recipient is not on the allowlist (see email_policy_status / email_allow). When the confirm-before-sending rule is on, the first call sends nothing and returns a confirmation request; call again with confirm=true once the person has approved.

  • set_send_confirmation

    Turn the 'confirm before sending' rule on or off. When on, send_message sends nothing until it is called again with confirm=true, so a person can approve first. If PROTON_REQUIRE_SEND_CONFIRMATION is set, the rule is forced on and cannot be turned off here.
