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 | $0.00666 | $0.00666 |
| Opus 5.5 | $0.00266 | $0.00266 |
| Sonnet 5.5 | $0.00133 | $0.00133 |
| Haiku 4.5 | $0.00067 | $0.00067 |
Grade A, and why
whisper-transcribe-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 1mo 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.

Project Overview
whisper-transcribe-mcp is a Python MCP (Model Context Protocol) server that exposes audio transcription tools using either faster-whisper (local, offline) or the OpenAI Whisper API (cloud). Published on PyPI and consumed via uvx or pip.
Development Setup
# Install with all optional backends (recommended for development)
pip install -e ".[all]"
# Or with uv
uv pip install -e ".[all]"
Running the Server Locally
# Local backend
WHISPER_MODEL=base python -m whisper_transcribe.server
# OpenAI backend
OPENAI_API_KEY=sk-... python -m whisper_transcribe.server
Building and Publishing
# Build the package
python -m build
# Release a new version (bumps version in pyproject.toml, commits, pushes, creates GitHub release)
# PyPI publish is triggered automatically via GitHub Actions on release
./release.sh 1.2.3
Architecture
The entire server lives in a single file: whisper_transcribe/server.py.
- Built on FastMCP (
fastmcp>=3.2.0, the first release without known advisories), which handles MCP protocol, tool registration, and stdio transport. - Backend selection is determined at startup by the presence of
OPENAI_API_KEY— there is no runtime switching. - The local
WhisperModelis lazily loaded and cached in_local_model(module-level global), and reloaded only if the requestedmodel_sizechanges. transcribe_base64delegates totranscribe_fileafter writing a temp file, then cleans it up.- Tool inputs (
language,model_size,extension) are validated against allowlists before use; OpenAI errors are summarized (type + HTTP status) and the raw message only goes to stderr.

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.
