The macOS runtime is available today; the iOS runtime is in preview. ```text "Brief me on today's calendar, overdue reminders, and unread mail." "For my next meeting, pull up the related notes, contacts, files, and reminders." "Search my Safari tabs for that article and save a summary to Notes." "Draft replies to the urgent mail, but ask me before sending anything." "Run my Morning Routine shortcut." ``` Start on macOS with Node.js 20+: ```bash npx airmcp init ``` Then ask your client. Works with Claude, Codex, Cursor, Raycast, Xcode agents, and any other MCP client. Nothing reads or changes a client's settings until you opt in. More to try: [Common Workflows](#common-workflows) · [every tool](llms-full.txt) · [Quick Start](#quick-start) ### It does not act behind your back AirMCP is the connector and control layer, not another agent. Destructive calls preview before they run, approval is per-call, and the audit chain is tamper-evident and verifiable by you — read `airmcp://trust` and check it yourself. Details in [Safety Model](#safety-model). <p align="center"> <a href="docs/demo.gif"><img src="docs/demo.gif" alt="A real AirMCP session showing the live trust verdict, a destructive delete previewed without executing, and a verified audit chain" width="900"></a> </p> <p align="center">Generated from a real local MCP round-trip by <code>scripts/demo/governed-flow.mjs</code> — real terminal output, not a staged transcript.</p> > Multi-language project page: [heznpc.github.io/AirMCP](https://heznpc.github.io/AirMCP/) ## What You Get - **Apple workspace tools** for Notes, Reminders, Calendar, Contacts, Mail, Messages, Music, Finder, Safari, Photos, Shortcuts, system control, screen capture, Weather, Maps, Location, Bluetooth, and more. - **Google Workspace tools** for Gmail, Drive, Sheets, Calendar, Docs, Tasks, People, and raw `gws` CLI access. - **Profiles and progressive exposure** so clients start with a small front door instead of every loaded tool. - **Skills DSL workflows** with `parallel`, `loop`, `retry`, `on_error`, runtime inputs, and event triggers. - **App Intent action bridge** generated from the MCP manifest for macOS Shortcuts, with an iOS-only App Shortcuts provider and destructive intents gated separately. - **Native Swift bridge** for EventKit, PhotoKit, HealthKit, Vision, on-device semantic search, and FoundationModels preview builds. AirMCP.app embeds the normal bridge; it is optional for npm and MCPB users, who can build it separately when needed. - **Dual transport**: stdio for standard MCP clients, HTTP/SSE for shared local runtimes, browser clients, registries, and always-on hosts. ## Apple Platform Direction AirMCP is one governed action layer with platform-specific roles, rather than a copy of the full Mac runtime on every device. | Platform | Status | Role | | --- | --- | --- | | macOS | Available | Full local MCP runtime and broad Apple app and system integration. | | iOS / iPadOS | Preview | Native Calendar, Reminders, Contacts, Health, and Location actions, plus in-process AppIntents. | | visionOS | Roadmap | Spatial interaction and native actions, with Mac routing for Mac-only automation. | | watchOS | Roadmap | Commands, notifications, and per-call approval through a paired iPhone runtime. | The shared Swift and AppIntents layers are the portability boundary. Platform sandboxing and lifecycle rules still determine which actions run locally and which route to a paired Mac or iPhone. ## Quick Start ### Claude Desktop one-click 1. Download `airmcp-<version>.mcpb` from [Releases](https://github.com/heznpc/AirMCP/releases). 2. Drag it onto Claude Desktop, or use **Settings -> Extensions -> Install from file...**. 3. Choose modules in the install form and finish setup. Full guide: [docs/mcpb.md](docs/mcpb.md). ### macOS app (signed + notarized) Every release from v2.16.5 on ships a Developer-ID-signed, notarized, and stapled `AirMCP-<version>.zip` in [Releases](https://github.com/heznpc/AirMCP/releases). It is the one artifact with the full surface and no build step: the embedded Node runtime, the Swift bridge, the menubar Trust Center, and the generated App Intents (Shortcuts actions) and widget are all included. Install v2.16.5 or later. The v2.16.3 and v2.16.4 releases carry an app ZIP that signs, notarizes, and staples correctly but crashes on launch before the menubar icon appears — a resource-bundle path bug fixed in v2.16.5. 1. Download `AirMCP-<version>.zip` and unzip it. 2. Move `AirMCP.app` to `/Applications` and open it. Gatekeeper accepts it offline because the notarization ticket is stapled. 3. Follow the consent-driven Setup window; nothing starts and no client is edited until you choose it. ### CLI wizard Install Node.js 20+, then run: ```bash npx airmcp init ``` The wizard selects a profile and stores preferences in `~/.config/airmcp/config.json`. Client registration is a separate consent step whose default is **No**; no Claude, Codex, Cursor, or Windsurf setting is read or changed until you opt in. For Codex, Claude Code, Cursor, Windsurf, and other stdio clients, use the direct runtime, or the app-owned runtime after installing the signed `AirMCP-<version>.zip` that ships with each release since v2.16.5: ```bash npx airmcp init --no-clients npx airmcp connect-clients --client-runtime direct --dry-run npx airmcp connect-clients --client-runtime direct ``` The app-owned runtime is available only after installing that signed app ZIP and explicitly choosing **Start Local Runtime**. Releases before v2.16.5 have no app asset, or one that cannot launch; do not configure a client to wait for AirMCP.app on those. Non-interactive examples: ```bash npx airmcp init --profile starter --yes npx airmcp init --profile communications-safe --yes npx airmcp init --profile productivity --yes npx airmcp init --profile productivity --yes --connect-clients npx airmcp init --profile productivity --yes --connect-clients --client-runtime direct ``` Check the install: ```bash npx airmcp doctor ``` ## Common Workflows Once connected, ask your MCP client in natural language: - "Tell me today's calendar events and overdue reminders. Do not change anything." - "Brief me on today's calendar, overdue reminders, unread mail, and recent notes." - "Turn today's meetings into a prep checklist." - "Draft replies for urgent mail, but ask before sending anything." - "For my next meeting, find related notes, contacts, files, and reminders." - "Search my Safari tabs for that article and save the summary to Notes." - "Run my Morning Routine shortcut." - "Take a screenshot and save it to my Desktop." More workflow examples live in [docs/workflows.md](docs/workflows.md). ## Runtime Model AirMCP is designed to keep a large local capability surface usable without dumping the full catalog into every client context. The complete generated catalog currently contains 298 tools across 32 modules. Profiles and progressive exposure keep clients from loading it all at once. - **Profiles**: `starter`, `communications-safe`, `productivity`, `full`, or `custom`. - **Tool exposure**: `progressive`, `profile`, or `full`. - **Module packs**: enable only the packs you want with `npx airmcp modules` or `AIRMCP_MODULE_PACKS=core,productivity`. - **Task sessions**: `start_tool_session`, `discover_tools`, and `run_tool` allow a broad runtime to behave like a narrow task-specific toolbelt. - **Opt-in network modules**: `webhooks` and `powerautomate` stay off in every profile until explicitly enabled. Useful commands: ```bash npx airmcp modules npx airmcp modules enable productivity --install npx airmcp --full npx airmcp workflows npx airmcp workflows --readiness npx airmcp workflows today-overview --prompt ``` `today-overview` is the starter-safe first workflow: it reads only Calendar and Reminders and never writes data. Paste the printed prompt into a connected MCP client for a governed first run with client authorization and AirMCP audit coverage. `workflows <id> --preview` is a separate local diagnostic. It reads Apple apps directly, bypasses the MCP governance path, and creates no AirMCP audit entry; do not use it as the first-success workflow. Broader diagnostics such as `daily-briefing --preview` report missing modules before reading live data. The complete generated tool manifest is in [docs/tool-manifest.json](docs/tool-manifest.json). Current generated surfaces: 234 App Intent action types, 86 Interactive Snippet views, 15 AppEnum pickers, and an iOS-only provider with 8 read-only App Shortcuts that match the preview runtime. The sessionless discovery card uses MCP schema version 2025-11-25. ## Safety Model AirMCP treats local app access as a governed action layer, not a blind shell for agents. The claim is verifiable, not marketing: read the first-party `airmcp://trust` resource for a live `governed` verdict composed from the tamper-evident audit chain, the active HITL level, the rate-limit / emergency-stop state, and the audit key grade — available before any tool access is widened. Preview any destructive call with `preview_action` to see exactly what it would record and whether it would be gated, without running it. - **Per-call human approval** for destructive and sensitive actions at the default `sensitive-only` HITL level. - **HMAC-chained audit log** at `~/.airmcp/audit.jsonl`, with tamper detection covered by tests. - **Native Trust Center** for governed-run timelines, approval state, audit integrity, emergency controls, permission probes, and redacted local export. Audit history is never read in the background: **Load** or **Refresh** makes one explicit `audit_log` request, and the effective HITL policy may require approval for that call. - **Rate limits**: 60/min globally and 10 destructive/hr. - **Emergency stop**: `touch ~/.config/airmcp/emergency-stop` blocks destructive tools without restarting the server. - **Inbound HTTP policy** through `AIRMCP_ALLOW_NETWORK`: loopback-only by default, with token, origin, or OAuth modes available for wider exposure. - **OAuth 2.1 + Resource Indicators** for HTTP runtimes that need scoped access control, with RS256/ES256 JWT verification. Environment variables are indexed in [docs/environment.md](docs/environment.md). HTTP policy details are in [RFC 0002](docs/rfc/0002-http-allow-network.md), and OAuth details are in [RFC 0005](docs/rfc/0005-oauth-resource-indicators.md). ## Client Setup Each release since v2.16.5 includes a runnable signed AirMCP.app ZIP; the app-owned desktop pattern keeps one local runtime behind every connected client. A per-install token is created only by an explicit action: **Start Local Runtime** in AirMCP.app, or an opted-in app-runtime client connection such as `--connect-clients` / `connect-clients`. It is stored at: ```text ~/Library/Application Support/AirMCP/http-token ``` The macOS Setup window is consent-driven: it appears automatically once and resumes its last step when reopened. Merely opening or moving through Setup does not start the runtime or edit a client, and first-run **Finish Later** with no runtime saves the selection only. If an app-owned runtime is already running and the selection changed, **Finish Setup** may stop and restart that exact owned generation so the persisted and effective scopes match. **Start Local Runtime** creates the token and opts into automatic startup; each client is registered only after its own **Connect** action and a fresh scope/readiness check. Existing Codex registrations can be inspected or disabled without deleting their settings: ```bash npx airmcp codex status npx airmcp codex disable ``` The `npx airmcp codex` commands follow their child Codex CLI's active user config root: `AIRMCP_CODEX_CONFIG_PATH` first, then `$CODEX_HOME/config.toml`, then `~/.codex/config.toml`. The explicit override is resolved against the invoking working directory and must be named `config.toml`. Stdio clients can proxy into the app-owned HTTP runtime: ```bash npx -y airmcp connect --url http://127.0.0.1:3847/mcp ``` Set `AIRMCP_HTTP_TOKEN` to the token value when using that proxy. Examples: ```bash claude mcp add --env AIRMCP_HTTP_TOKEN=<token> airmcp -- npx -y airmcp connect --url http://127.0.0.1:3847/mcp codex mcp add --env AIRMCP_HTTP_TOKEN=<token> airmcp -- npx -y airmcp connect --url http://127.0.0.1:3847/mcp ``` Direct stdio mode still works for development or isolated client-owned runtimes: ```bash npx -y airmcp ``` Browser-based MCP clients should use HTTP mode with token and origin checks. See [docs/oauth-browser-pkce.md](docs/oauth-browser-pkce.md) for the browser/OAuth path. ## App Intents and Shortcuts AirMCP generates App Intent actions from the same MCP tool manifest. On macOS, those actions are available in the Shortcuts action library; Apple does not support the `AppShortcutsProvider` phrase surface on macOS. iOS preview builds can additionally compile the workflow-first App Shortcuts provider. Destructive intent source generation is opt-in at build/codegen time with `AIRMCP_APPINTENTS_DESTRUCTIVE=true`; setting it beside an already-built app does not expand that binary's intent surface. `AskAirMCPIntent` and FoundationModels-backed Apple Intelligence paths are preview-only and require explicit Swift builds. Guide: [docs/shortcuts.md](docs/shortcuts.md). Architecture: [RFC 0007](docs/rfc/0007-app-intent-bridge.md). ## Local Development ```bash git clone https://github.com/heznpc/AirMCP.git cd AirMCP npm install npm run build node dist/index.js ``` Useful checks: ```bash npm test npm run mcp:validate npm run dev:test -- notes npm run dev:test:changed ``` Swift bridge: ```bash npm run swift-build ``` FoundationModels preview builds require macOS 26+, Apple Silicon, a compatible SDK, and the explicit compile flag: ```bash cd swift swift build -c release -Xswiftc -DAIRMCP_ENABLE_FOUNDATION_MODELS ``` Local build artifacts can grow after Swift or app builds. To inspect or reclaim ignored artifacts: ```bash npm run clean:local npm run clean:local:apply npm run size:check ``` Testing guide: [docs/testing.md](docs/testing.md). ## Requirements - macOS for the server runtime. - Node.js 20 or newer. - macOS Automation, Accessibility, Full Disk Access, Location, Bluetooth, or Photos permissions as required by the modules you enable. - The self-contained AirMCP.app distribution embeds its fixed Node runtime and the normal Swift bridge. The npm package and `.mcpb` do not embed the Swift binary; users of those artifacts build it from source for Swift-backed tools, or install the signed AirMCP.app release asset, which embeds it. - FoundationModels-backed Apple Intelligence preview requires macOS 26+, Apple Silicon, and `AIRMCP_ENABLE_FOUNDATION_MODELS`. The macOS runtime is the current supported release. The iOS runtime is a preview; visionOS and watchOS are roadmap targets, not released products. ## Documentation - [Tool manifest](docs/tool-manifest.json): generated list of registered tools. - [Workflows](docs/workflows.md): target workflows and prompt catalog. - [Skills DSL](docs/skills.md): YAML workflow syntax and built-ins. - [Shortcuts](docs/shortcuts.md): macOS App Intent actions and the iOS-only App Shortcuts surface. - [Environment variables](docs/environment.md): all runtime knobs. - [MCPB install](docs/mcpb.md): Claude Desktop extension package. - [OAuth browser PKCE](docs/oauth-browser-pkce.md): browser client setup. - [RFC index](docs/rfc/README.md): design records and architecture notes. - [Testing](docs/testing.md): development test workflow. - [Project direction](docs/direction.md): product direction and positioning. ## Contributing See [CONTRIBUTING.md](CONTRIBUTING.md) for development setup, code style, and PR guidelines.
