iMessage Max

Overview

iMessage Max is an MIT-licensed MCP server for iMessage by cyberpapiii (github.com/cyberpapiii/imessage-max), written in Swift as a single binary. It reads the Messages database on your Mac, resolves phone numbers to names through Contacts and sends through Messages.app automation. It installs through Homebrew or a source build and needs macOS 15 or later. The latest release is v1.8.0 (October 12, 2026).

Key features

• 13 tools, including find_chat, get_messages, search, get_context, get_unread and send
• Send text or files to a contact or an existing chat, including group chats
• Read reactions, inline replies and edit markers (read-only)
• Image attachments in three sizes (1568px, 400px or original)
• Cursor-based get_messages_since for polling, plus a notification when new messages arrive
• Send results checked against the Messages database, with delivery errors reported
• stdio or HTTP transport, with an optional launchd background service

Pricing

Free, open-source software. It needs a Mac on macOS 15 or later that is signed in to iMessage.

How it compares to Linq

Linq is a managed API with its own phone numbers, iMessage, RCS and SMS, webhooks, SDKs and sending of tapbacks, typing indicators and effects, with a free Hobby plan (20 contacts) and Pro from $260 a month. iMessage Max is free and runs under your own Apple ID on your Mac. It is used from MCP clients rather than a REST API, cannot send tapbacks, edits or unsends, and has no webhooks.

Best for

People who want an AI assistant to search, summarize and answer their own iMessages on a Mac.
