io.github.chrischall/apple-icloud-mcp
Unofficial: Apple Music, iCloud Calendar/Contacts/Mail, Apple Maps and WeatherKit, no Mac needed
The current version, v0.1.0, was published to the official MCP registry on 2026-09-27. It is distributed as apple-icloud-mcp on npm, filed under Maps & Location by this index, and declares 30 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).
Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less
uv tool install mcpindex-gate && mcpindex-config-wireVerdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

That verdict was true at screening time (snapshot 2026-09-27).
Contracts can change after screening, with no version bump. The gate pins io.github.chrischall/apple-icloud-mcp’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

APPLE_TEAM_IDYour Apple Developer Team ID (10 characters). Needed for Apple Music (official API), Apple Maps and WeatherKit.
APPLE_KEY_IDKey ID of a private key created in Certificates, Identifiers & Profiles → Keys with Media Services (MusicKit), MapKit JS and/or WeatherKit enabled.
APPLE_PRIVATE_KEYContents of that key's .p8 file (PEM; one-line values with \n escapes and base64 are accepted).
APPLE_PRIVATE_KEY_PATHLocal installs only: a path to the .p8 file instead of APPLE_PRIVATE_KEY.
APPLE_MUSIC_KEY_IDOptional per-service override of APPLE_KEY_ID for Apple Music (pair with APPLE_MUSIC_PRIVATE_KEY).
APPLE_MUSIC_PRIVATE_KEYOptional per-service override of APPLE_PRIVATE_KEY for Apple Music.
APPLE_MAPS_KEY_IDOptional per-service override of APPLE_KEY_ID for Apple Maps.
APPLE_MAPS_PRIVATE_KEYOptional per-service override of APPLE_PRIVATE_KEY for Apple Maps.
APPLE_WEATHERKIT_KEY_IDOptional per-service override of APPLE_KEY_ID for WeatherKit.
APPLE_WEATHERKIT_PRIVATE_KEYOptional per-service override of APPLE_PRIVATE_KEY for WeatherKit.
APPLE_WEATHERKIT_SERVICE_IDWeatherKit only: the Services ID registered for WeatherKit (e.g. com.example.weather).
APPLE_MUSIC_DEVELOPER_TOKENOptional: a pre-minted Apple Music developer token (JWT) instead of signing one from the key above.
APPLE_MUSIC_USER_TOKENMusic 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.
APPLE_MUSIC_WEB_USER_TOKENOpt-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.
APPLE_MUSIC_WEB_DEVELOPER_TOKENOptional override for the web-player developer token (normally read automatically from music.apple.com).
APPLE_MUSIC_STOREFRONTTwo-letter Apple Music storefront (e.g. us, gb). Default: your account's storefront, else us.
ICLOUD_USERNAMEYour Apple ID email, for iCloud Calendar, Contacts and Mail.
ICLOUD_APP_PASSWORDAn app-specific password from appleid.apple.com → Sign-In and Security → App-Specific Passwords (NOT your Apple ID password).
ICLOUD_MAIL_ADDRESSYour @icloud.com address, only if your Apple ID email is not an iCloud address (needed for Mail).
ICLOUD_DEFAULT_CALENDARCalendar new events go to when none is named (default: the first writable event calendar).
APPLE_WRITE_MODE"none" = read-only tools; "additive" = also create/append, never modify, delete or send; "all" = everything (default). Unrecognized values fail closed to "none".
APPLE_SERVICESComma-separated services to enable (music, calendar, contacts, mail, maps, weather, itunes). Default: all.
DISPLAY_TZIANA 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"metric" (default) or "imperial" units for weather (Maps distances always show both).
APPLE_STATE_CACHESet 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_MSPer-request timeout in milliseconds (default 30000).
APPLE_DEBUG_LOGSet to 1 to log every upstream request line to stderr (credentials redacted).
MCP_CONFIRM_MODEHow 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_TTL_SECONDSLifetime of a confirmToken in seconds (default 600).
MCP_CONFIRM_SECRETSigning 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).
