"Proton" matching MCP servers:

A safe-by-default MCP server that gives Claude access to your Proton Mail through Proton Mail Bridge's localhost IMAP/SMTP. Sending requires human approval and destructive operations are limited.

Enables MCP clients to read and search Proton Mail and create draft-only emails with attachments through the local Proton Mail Bridge, while requiring out-of-band human approval before a draft can be committed.

Enables AI assistants to read, organize, and send Proton Mail through the local Proton Bridge, with careful gating for sending and attachment access.

MCP server for reading and searching Proton Mail via Proton Mail Bridge, providing tools to list mailboxes, list/search messages, and get message details with TLS certificate pinning.

Enables Claude to read-only browse, search, and fetch emails from a Proton Mail inbox through Proton Bridge IMAP, with no capabilities to send, move, flag, or delete.

Enables sending correctly threaded email replies through Proton Mail Bridge using SMTP with proper In-Reply-To and References headers, avoiding IMAP draft pitfalls.

Self-hosted MCP server that enables reading, sending, and automating Proton Mail via Bridge, with optional SimpleLogin alias management.

Provides read-only access to Proton Mail via MCP, enabling AI agents to list accounts/folders, search messages, and read emails using Proton Mail Bridge's local IMAP server.

Enables AI assistants to interact with a Proton Mail mailbox through Proton Bridge, supporting listing, searching, reading, sending, and organizing emails.

Enables AI agents to read a Proton Mail mailbox through a local Proton Bridge instance, listing folders, browsing recent messages, running full-text searches, and reading individual messages with decoded bodies and attachment info. All access is read-only — mailboxes are opened in IMAP READONLY mode, so nothing is ever modified, and the capability model lets operators opt into future draft, organize, send, and delete tools behind explicit confirmations.

A read-only MCP server that lets ChatGPT search and read a Proton Mail account through Proton Mail Bridge. It provides mailbox listing, mail search, and single-message retrieval without the ability to send, modify, or delete email.

A lightweight MCP server providing AI agents a scoped, read-and-draft-only view into Proton Mail via Proton Bridge, with code-enforced restrictions preventing external access or sending.

A security-first MCP server that provides AI agents with a scoped, read-and-draft-only view into Proton Mail via Proton Bridge, ensuring no emails can be sent and access is restricted to configured workspaces.
