# ⚛️ Nucleus: macOS Life Context Server

**Give your AI Agent a Hippocampus.**

`nucleus-apple-mcp` is a Model Context Protocol (MCP) server designed to unify your digital life on macOS. It allows AI agents (like Claude Desktop, Cursor, or custom agents) to securely read and interact with your personal data ecosystem.

Unlike fragile PyObjC bridges, **Nucleus** uses a hybrid architecture: a Python MCP server that orchestrates lightweight, JIT-compiled native Swift workers. This ensures type-safe, performant, and reliable access to Apple's native APIs while remaining easily distributable via `uvx`.

## 🔌 Integrations

### ✅ Available (current release)

* **📅 Calendar:** Fetch upcoming schedules, check availability, and create events via `EventKit`.
* **✅ Reminders:** Read pending tasks and manage your to-do lists via `EventKit`.

### 🚧 Planned (not implemented yet)

* **📝 Notes:** Access your Apple Notes database (the "Second Brain" memory layer).
* **❤️ Health:** Ingest health metrics (sleep, heart rate, activity) via iOS-to-Mac iCloud exports.

### 🏗 Architecture

* **Python:** Handles the MCP protocol, request routing, and distribution (pip/uv).
* **Swift:** Embedded source code acts as a "Sidecar." It is compiled locally on the first run (using SwiftPM `swift build`) to interface directly with macOS private frameworks, bypassing the limitations of Python-Objective-C bridges.

### 📦 Swift Sidecar Layout

* **Swift Package Root:** `src/nucleus_apple_mcp/sidecar/swift/` (includes `Package.swift`; CLI uses `swift-argument-parser`)
* **Build Cache (macOS):** `~/Library/Caches/nucleus-apple-mcp/sidecar/<build_id>/nucleus-apple-sidecar`
* **Optional Env Vars:** `NUCLEUS_APPLE_MCP_CACHE_DIR` (overrides cache directory), `NUCLEUS_SWIFT` (swift path), `NUCLEUS_SWIFTC` (swiftc path)

### 🚀 Usage

```bash
# No manual compilation required.
# The Python wrapper handles the local Swift build automatically.
uvx nucleus-apple-mcp
```

## 🔧 Add as an MCP server

This server uses the **stdio** transport (a local subprocess). The first run will compile the Swift sidecar.

### Codex CLI

```bash
# Add the server (writes to ~/.codex/config.toml)
codex mcp add nucleus-apple -- uvx nucleus-apple-mcp

# Verify
codex mcp list
```

### Claude Code

```bash
# Add the server (use --scope user to make it available globally)
claude mcp add --scope user nucleus-apple -- uvx nucleus-apple-mcp

# Verify
claude mcp list
```
