"Proton Mail" matching MCP servers:

Professional Proton Mail management with 20+ tools, advanced analytics, and seamless Proton Bridge integration.

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.

Baryon connects MCP-compatible AI assistants to Proton Mail through a local bridge, enabling email search, reading, attachment handling, and draft creation while enforcing deliberate permission limits. It runs locally and cannot send, delete, or modify mail.

Provides AI agents with real email infrastructure, enabling them to create inboxes, send/receive messages, and extract verification codes from incoming mail.

MCP server that provides full access to Proton Drive via Claude Desktop or CLI, enabling file operations, sharing, and trash management with end-to-end encryption.

Enables LLMs to read, search, file, and send iCloud Mail via IMAP and SMTP, with local-only credential handling and read-only tools by default.

An MCP server that gives AI agents permission-gated, audit-logged access to private email providers (Proton Mail via Bridge and plain IMAP), running locally with OAuth-based authentication and human-controlled escalation for destructive operations.

Read and write email through the Atomic Mail from an AI agent. Handles proof-of-work authentication and JMAP so the agent thinks in JMAP method calls. Use when the user asks to register an email inbox, list mailboxes, fetch or send email.

It enables AI assistants to search, read, and draft email in a Gmail inbox, and at the highest access level to send mail and reorganize labels, archive, or trash messages. Access is gated behind three levels — read-only by default, drafts-only, and full — so the model is only offered the tools its configured level permits.

MCP server to administer a Mailu mail server from Claude — domains, mailboxes, aliases and forwards.

Full-stack email MCP server in Rust: IMAP, SMTP, Exchange Web Services, and Microsoft Graph in one binary, with OAuth2 and multi-account support. Read, search, send, reply, forward, bulk operations, and attachment download to disk.

A TypeScript MCP server that enables LLMs to send outbound emails via SMTP with support for attachments and HTML content. It includes outcome-oriented tools for account validation and enforces strict security policies like recipient allowlists and size limits.

Serves a strictly read-only mail archive over MCP: ordered filter rules pull matching messages from any IMAP mailbox or the Gmail API and write them to disk as byte-faithful .eml plus markdown with YAML frontmatter. Exposes list_rules, list_messages, search_messages, read_message (with full-thread reads) and sync; it never sends, deletes or modifies mail.

MCP server for any IMAP mailbox that lets AI models read, search, send, and manage email, including processing attachments as images.

MCP server that sends mail over SMTP, gated behind an allowlist and a human confirmation

A brain for your mail: MailFathom turns IMAP mailboxes into a self-hosted, AI-native service.

Enables MCP clients to read, search, organise, and manage IMAP mailbox messages, including saving attachments and drafting replies, while treating mail content as untrusted and keeping write capabilities opt-in.
