Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02429 | $0.02429 |
| Opus 5 | $0.01215 | $0.01215 |
| Sonnet 5 | $0.00486 | $0.00486 |
| Haiku 4.5 | $0.00243 | $0.00243 |
Grade A, and why
icloud-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iCloud MCP Server
This MCP server provides Claude with access to Apple services via two modes:
Modes
| Mode | Description | Services | Requirements |
|---|---|---|---|
| LOCAL (default) | AppleScript access to macOS apps | 7 services, 41 tools | macOS |
| CLOUD | iCloud protocols (IMAP, CalDAV, CardDAV) | 3 services, 41 tools* | App-specific password |
* In CLOUD mode, local-only tools (Reminders, Notes, Messages, Safari) return an error when called.
Runtime Mode Switching
Use set-mode to switch between modes without restarting:
set-mode local→ AppleScript access to all macOS appsset-mode cloud→ iCloud protocols (requires credentials)
Services Available
Local Mode (macOS only)
| Service | Protocol | Tools |
|---|---|---|
| Mail.app (AppleScript) | 6 | |
| Calendar | Calendar.app (AppleScript) | 5 |
| Contacts | Contacts.app (AppleScript) | 7 |
| Reminders | Reminders.app (AppleScript) | 7 |
| Notes | Notes.app (AppleScript) | 5 |
| Messages | Messages.app + imsg CLI |
4 |
| Safari | Safari.app (AppleScript) | 4 |
All seven services now honour the mode. Email and Calendar route through
local-client.js in LOCAL mode and IMAP/SMTP/CalDAV in CLOUD mode.
Field differences between modes (normalized where possible):
| Field | LOCAL | CLOUD |
|---|---|---|
Email handle (uid arg) |
Mail.app message ID | IMAP UID |
| Event/calendar handle | Calendar.app UID / calendar name | CalDAV URL |
| Email unread flag | read boolean |
\Seen in flags |
| Event end time | available | available |
send-email message ID |
not returned by Mail.app | returned by SMTP |
create-event target |
calendarName |
calendarUrl |
Handlers normalize these to a common shape (ref, unread, start/end),
so a tool returns the same field names in both modes. The two genuinely
unavailable values are the SMTP message ID and isHtml (Mail.app sends plain
text), which are simply omitted in LOCAL mode.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
