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 | $0.12865 | $0.12865 |
| Opus 5.5 | $0.05146 | $0.05146 |
| Sonnet 5.5 | $0.02573 | $0.02573 |
| Haiku 4.5 | $0.01286 | $0.01286 |
Grade A, and why
apple-notes-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 7d 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 — 462 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md - Apple Notes MCP Server
This file provides guidance for AI agents (Claude, etc.) when using this MCP server.
Overview
This MCP server lets AI assistants work with Apple Notes on macOS through AppleScript, signed Shortcuts, and read-only database access. Notes operations run locally; the MCP client receives their results and applies its own data handling. Optional speech-model downloads are separate from on-device transcription.

Critical: Backslash Escaping
When sending content with backslashes to any tool, you MUST escape them.
The MCP protocol uses JSON for parameters. In JSON, \ is an escape character. To include a literal backslash:
| You want | Send in JSON parameter |
|---|---|
\ |
\\ |
\\ |
\\\\ |
Mobile\ Documents |
Mobile\\ Documents |
Why This Matters
If you send a single backslash without escaping:
- The JSON parser interprets
\as an escape sequence - Invalid sequences like
\(backslash-space) cause silent failures - The note creation/update will fail with no clear error
Examples
Correct - Shell command with escaped space:
content: "cp ~/Library/Mobile\\ Documents/file.txt ~/dest/"
→ arrives as: cp ~/Library/Mobile\ Documents/file.txt ~/dest/
Correct - Regex pattern:
content: "Version pattern: \\d+\\.\\d+"
→ arrives as: Version pattern: \d+\.\d+
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.
