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 | $0.00271 | $0.00271 |
| Opus 5 | $0.00135 | $0.00135 |
| Sonnet 5 | $0.00054 | $0.00054 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
apple-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.
This is a copy
100% identical to apple-mcp CLAUDE.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
apple-mcp Development Guidelines
Commands
bun run dev- Start the development server- No specific test or lint commands defined in package.json
Code Style
TypeScript Configuration
- Target: ESNext
- Module: ESNext
- Strict mode enabled
- Bundler module resolution
Formatting & Structure
- Use 2-space indentation (based on existing code)
- Keep lines under 100 characters
- Use explicit type annotations for function parameters and returns
Naming Conventions
- PascalCase for types, interfaces and Tool constants (e.g.,
CONTACTS_TOOL) - camelCase for variables and functions
- Use descriptive names that reflect purpose
Imports
- Use ESM import syntax with
.jsextensions - Organize imports: external packages first, then internal modules
Error Handling
- Use try/catch blocks around applescript execution and external operations
- Return both success status and detailed error messages
- Check for required parameters before operations
Type Safety
- Define strong types for all function parameters
- Use type guard functions for validating incoming arguments
- Provide detailed TypeScript interfaces for complex objects
MCP Tool Structure
- Follow established pattern for creating tool definitions
- Include detailed descriptions and proper input schema
- Organize related functionality into separate utility modules
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.
