"Proton Mail" matching MCP servers:

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

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.

Enables reading, converting, and managing email messages, calendars, and contacts, along with mail account folder/thread operations and personal name parsing/formatting, via typed MCP tools.

One endpoint in front of 950+ data APIs — SEO and AI visibility, finance, social, web search, sales and agent mail. tools/list returns five meta tools, not 580, so the catalogue never lands in a context window. Most clients can point straight at https://mcp.aisa.one/mcp; this package is the stdio bridge for the ones that only spawn a local command. OAuth, nothing to paste.

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.

Enables address validation, geocoding, postcode lookup, and reverse geocoding in 240+ countries, including UK Royal Mail PAF data, through four tools for MCP-aware clients.
