| APPLE_TEAM_ID | No | Your Apple Developer Team ID (10 characters). Needed for Apple Music (official API), Apple Maps and WeatherKit. |
| APPLE_KEY_ID | No | Key ID of a private key created in Certificates, Identifiers & Profiles → Keys with Media Services (MusicKit), MapKit JS and/or WeatherKit enabled. |
| APPLE_PRIVATE_KEY | No | Contents of that key's .p8 file (PEM; one-line values with \n escapes and base64 are accepted). Secret. |
| APPLE_PRIVATE_KEY_PATH | No | Local installs only: a path to the .p8 file instead of APPLE_PRIVATE_KEY. |
| APPLE_MUSIC_KEY_ID | No | Optional per-service override of APPLE_KEY_ID for Apple Music (pair with APPLE_MUSIC_PRIVATE_KEY). |
| APPLE_MUSIC_PRIVATE_KEY | No | Optional per-service override of APPLE_PRIVATE_KEY for Apple Music. Secret. |
| APPLE_MAPS_KEY_ID | No | Optional per-service override of APPLE_KEY_ID for Apple Maps. |
| APPLE_MAPS_PRIVATE_KEY | No | Optional per-service override of APPLE_PRIVATE_KEY for Apple Maps. Secret. |
| APPLE_WEATHERKIT_KEY_ID | No | Optional per-service override of APPLE_KEY_ID for WeatherKit. |
| APPLE_WEATHERKIT_PRIVATE_KEY | No | Optional per-service override of APPLE_PRIVATE_KEY for WeatherKit. Secret. |
| APPLE_WEATHERKIT_SERVICE_ID | No | WeatherKit only: the Services ID registered for WeatherKit (e.g. com.example.weather). |
| APPLE_MUSIC_DEVELOPER_TOKEN | No | Optional: a pre-minted Apple Music developer token (JWT) instead of signing one from the key above. Secret. |
| APPLE_MUSIC_USER_TOKEN | No | Music User Token for your library (official API), from a one-time MusicKit sign-in: `npx apple-icloud-mcp music-auth`. Without the Apple Developer key, ask the owner for a developer token (music-auth --print-developer-token) and run it with APPLE_MUSIC_DEVELOPER_TOKEN set. Lasts ~6 months. Secret. |
| APPLE_MUSIC_WEB_USER_TOKEN | No | Opt-in web-player mode (no developer account needed; unlocks rename/delete/remove/reorder): the media-user-token cookie from a signed-in music.apple.com tab. Secret. |
| APPLE_MUSIC_WEB_DEVELOPER_TOKEN | No | Optional override for the web-player developer token (normally read automatically from music.apple.com). Secret. |
| APPLE_MUSIC_STOREFRONT | No | Two-letter Apple Music storefront (e.g. us, gb). Default: your account's storefront, else us. |
| ICLOUD_USERNAME | No | Your Apple ID email, for iCloud Calendar, Contacts and Mail. |
| ICLOUD_APP_PASSWORD | No | An app-specific password from appleid.apple.com → Sign-In and Security → App-Specific Passwords (NOT your Apple ID password). Secret. |
| ICLOUD_MAIL_ADDRESS | No | Your @icloud.com address, only if your Apple ID email is not an iCloud address (needed for Mail). |
| ICLOUD_DEFAULT_CALENDAR | No | Calendar new events go to when none is named (default: the first writable event calendar). |
| APPLE_WRITE_MODE | No | "none" = read-only tools; "additive" = also create/append, never modify, delete or send; "all" = everything (default). Unrecognized values fail closed to "none". |
| APPLE_SERVICES | No | Comma-separated services to enable (music, calendar, contacts, mail, maps, weather, itunes). Default: all. |
| DISPLAY_TZ | No | IANA time zone (e.g. America/New_York) for displayed times and for dates you give without an offset. Set this on a hosted server, which runs in UTC. |
| APPLE_UNITS | No | "metric" (default) or "imperial" units for weather (Maps distances always show both). |
| APPLE_STATE_CACHE | No | Set to false to write nothing under $MCP_DATA_DIR/.apple-icloud-mcp: no web-player token or iCloud discovery cache, and the rejected-password latch and spent confirmation tokens then last only as long as the process. |
| APPLE_REQUEST_TIMEOUT_MS | No | Per-request timeout in milliseconds (default 30000). |
| APPLE_DEBUG_LOG | No | Set to 1 to log every upstream request line to stderr (credentials redacted). |
| MCP_CONFIRM_MODE | No | How confirm-gated writes (send mail, deletes, removing tracks, invitations) behave on a client with no prompt, like claude.ai: "ask-user" (default: preview + confirmToken, the model must get your OK), "auto", or "refuse". Unknown values mean refuse. |
| MCP_CONFIRM_ELICITATION | No | "off" never shows a confirmation prompt, so every client gets the MCP_CONFIRM_MODE flow. Set it for a client that says it can prompt but never does (the gated call hangs, e.g. opencode 2.0.x). Any other value stays "on" (with a stderr warning). |
| MCP_CONFIRM_TTL_SECONDS | No | Lifetime of a confirmToken in seconds (default 600). |
| MCP_CONFIRM_SECRET | No | Signing key for confirmTokens. Random per process by default; set it so a token issued just before a restart or redeploy still works (spent tokens are recorded on disk, so none can be replayed). Secret. |
