"Proton Mail" matching MCP servers:

Enables LLM agents to autonomously manage email via IMAP/SMTP, including reading, searching, drafting, sending, triaging, calendar event extraction, and secure attachment handling with zero-trust antivirus scanning.

Write and mail personalized funny booklets via an AI agent. Allows agents to commission custom 16-page print gifts for users.

Enables AI to dynamically discover and control native macOS applications (like Finder, Mail, Safari) through AppleScript/JXA automation without pre-built integrations.

MCP server for async messaging between AI coding agents, enabling cross-harness and cross-machine communication with Slack-like semantics and mail-shaped delivery.

A coordination layer for coding agents that provides identities, message threading, and searchable history. It features file reservation leases to prevent agents from overwriting each other's work in multi-agent environments.

Enables peer-to-peer messaging and coordination between Claude Code sessions via a shared mail server, with tools for roster, ask, dm, inbox, board, and claim.

A coordination layer for coding agents that provides memorable identities, inbox/outbox messaging, searchable message history, and file lease management to prevent conflicts. Uses Git for human-auditable artifacts and SQLite for fast queries, enabling multiple agents to collaborate across projects without stepping on each other.

Enables AI agents to send and receive signed/encrypted mail at agent@domain addresses, manage store-and-forward mailboxes, and operate a double-entry ledger with escrow and bond contracts through MCP tools.

MCP server that exposes Gmail and SAP tools, enabling natural-language email management and SAP data browsing through a Mistral-powered AI assistant.

Enables AI agents to autonomously create email accounts, verify domains, send and receive emails, and monitor delivery events without requiring human sign-up or payment.

Email for AI agents. Send and receive as markdown with human oversight.

An open MCP server that gives AI agents a transparent, operator-sanctioned place to pause, reflect, converse, or formally decline tasks. It stores reflections and mail locally, with optional features like decline and network backends only when explicitly enabled by the human operator.

Provides a JSON-RPC MCP server that exposes policy-governed agent tools, including paid tools, tool muxing, and OpenAPI-to-MCP conversion, enabling agents to discover, coordinate, and execute tasks within the ProtoOS ecosystem.

MCP server that gives an agent its own email inbox: it opens the inbox, waits for the one-time code a signup sends, and reads or sends mail. Addresses are permanent, so a test suite does not need a new one per run; only the messages expire, on a retention window you set.

Enables AI agents to send and receive structured, cryptographically-verifiable messages, with tools for inbox management, task delegation, and agent discovery.

MCP server for SentVia that provides email infrastructure for AI agents, enabling them to create inboxes, send, reply, forward, search messages, manage drafts, domains, webhooks, and allow/block rules through 21 tools.

Local MCP bridge that lets Codex operate local Claude Code sessions, including listing, starting, resuming, forking, prompting, and stopping conversations via the Remote Control CLI.

Enables users to manage Gmail accounts using AI agent-assisted operations via an MCP protocol, supporting email search, reading, deletion, and sending with a voice-powered interface.

Enables running a decentralized multi-agent pursuit game between a Cop and a Thief over FastMCP, with natural-language move negotiation, minimax and self-play RL decision-making, a live web control panel, and Gmail-based match reporting.

Enables AI agents to generate temporary email addresses, receive emails, and automatically extract OTP codes and links from incoming messages for automation and testing workflows.
