@agentick/connector-imessage

iMessage platform adapter for the Agentick connector system. macOS only.

Polls ~/Library/Messages/chat.db for incoming messages and sends responses via AppleScript through Messages.app.

Install

pnpm add @agentick/connector-imessage

Requires Node 22+ (node:sqlite built-in).

Prerequisites

Grant Full Disk Access to your terminal application in System Settings > Privacy & Security > Full Disk Access. Without this, the agent cannot read chat.db.

Usage

import { createConnector } from "@agentick/connector";
import { IMessagePlatform } from "@agentick/connector-imessage";

const connector = createConnector(
  client,
  new IMessagePlatform({
    handle: "+15551234567",
  }),
  {
    sessionId: "main",
    contentPolicy: "summarized",
    deliveryStrategy: "on-idle",
  },
);

await connector.start();

Options

interface IMessageConnectorOptions {
  handle: string;
  pollIntervalMs?: number;
  sendDelay?: number;
  dbPath?: string;
}

handle — Phone number (with country code) or email address to watch.

pollIntervalMs — How often to poll chat.db. Default: 2000ms.

sendDelay — Delay between sending multiple messages to avoid rate limiting by Messages.app. Default: 500ms.

dbPath — Custom path to chat.db (for testing).

How It Works

Inbound: Polls chat.db using node:sqlite. Tracks a ROWID watermark so each poll only returns new messages. Filters by handle and is_from_me = 0. Poll errors (e.g., SQLITE_BUSY when Messages.app holds a lock) are caught and retried on the next interval.

Outbound: Sends via osascript driving Messages.app. Text is escaped to prevent AppleScript injection.

Confirmations: Text-based only. Sends a prompt like "Allow shell to execute? Reply yes/no" and parses the next inbound message as the response. Natural language is supported — "yes but only in /tmp" is approved with the full text as reason.

Recommended Config

{
  contentPolicy: "summarized",   // clean summaries, no raw tool blocks
  deliveryStrategy: "on-idle",   // one polished message per execution
}

iMessage works best with "on-idle" delivery — one complete, well-composed message rather than a stream of fragments.
