### Description (declared)

# imsg — fast, local iMessage for your terminal & MCP

**Package brand:** `imsg-mcp` · **CLI/MCP:** `imsg` / `imsg-mcp` · **PyPI today:** `pip install mac-imsg` (target PyPI: `imsg-mcp`).

[![PyPI](https://img.shields.io/pypi/v/mac-imsg.svg)](https://pypi.org/project/mac-imsg/)
[![Python](https://img.shields.io/pypi/pyversions/mac-imsg.svg)](https://pypi.org/project/mac-imsg/)
[![Built with Rust](https://img.shields.io/badge/core-Rust-orange.svg)](rust/)
[![License: MIT](https://img.shields.io/badge/license-MIT-blue.svg)](LICENSE)
[![macOS only](https://img.shields.io/badge/os-macOS-black.svg)](#requirements)

Read, search, and send iMessage from your terminal — or expose it to Claude,
Cursor, VS Code, or any MCP client. Everything runs **locally on your Mac**:
no cloud, no login, no account. Reads open `~/Library/Messages/chat.db`
**read-only**; sends go through Messages.app.

**macOS only.** iMessage lives in Apple's local `chat.db` and Messages.app —
there is no official API and no equivalent on Linux or Windows, so `imsg`
only runs on macOS. See [Requirements](#requirements) for the Full Disk
Access setup every install needs.

**Why another one?** The hot path — decoding tens of thousands of
`attributedBody` typedstream blobs — is written in **Rust** (PyO3 + rusqlite),
so reads and searches over a large history are several times faster than the
pure-Python equivalent that other Messages servers use. Pure Python still ships
as a zero-dependency fallback, so it works even where the wheel doesn't.

### Benchmark

Full-history search over a synthetic **50,000-message** database (70% stored as
`attributedBody` blobs), best-of-5, Apple Silicon (16 cores):

| operation | pure-Python | Rust core | speedup |
|---|---:|---:|---:|
| **full-history search** (decodes every message) | 120.9 ms | **35.7 ms** | **3.4×** |
| batched blob decode (allocation-bound) | 19.1 ms | 19.6 ms | 1.0× |

Two honest caveats, stated up front:
- Raw blob decoding is ~a wash — i…
