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 | $0.00432 | $0.00432 |
| Opus 5 | $0.00216 | $0.00216 |
| Sonnet 5 | $0.00086 | $0.00086 |
| Haiku 4.5 | $0.00043 | $0.00043 |
Grade A, and why
mcp-server-whisper 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.

Code Style
- Line length: 120 characters
- Use type hints for all functions and variables
- Import order: standard library → typing → third-party → local
- Use async/await for I/O operations
- Use Pydantic models for data validation
- Function/variable naming: snake_case
- Class naming: PascalCase
- Constants: UPPER_SNAKE_CASE
- Follow Google docstring style for documentation
Error Handling
- Use specific exceptions with descriptive messages
- Propagate exceptions with
raise ... from e - Handle errors at appropriate abstraction levels
- Log errors with context information
MCP Implementation
- Tools are defined with
@mcp.tool()decorator - Resources are defined with
@mcp.resource()decorator - Use batch processing with lists of inputs for parallel operations
- Process multiple files concurrently using
asyncio.gather() - Return structured data (typically Dict[str, Any]) for consistent handling
Audio Processing
- Supports multiple formats: mp3, wav, mp4, mpeg, mpga, m4a, webm
- GPT-4o direct access supports: mp3, wav
- Files over 25MB are automatically compressed
- Parallel processing for batch transcription jobs
- Transcription options: basic Whisper, GPT-4o with prompt, enhanced transcription
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.

mcp-server-whisper CLAUDE.md is an instructions file published in the GitHub repository arcaputo3/mcp-server-whisper (60 stars, last pushed 4mo ago), licensed MIT. It adds 432 tokens to every session, about $0.0022 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
