How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security40
- Malware scan not yet available for this package.Unverified
- CVE check failed: a known medium-severity CVE affects fastmcp 4.1.0, a direct dependency. A fixed version is available. View diagnostics → Fail
- Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 1 of 15 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to docdyhr/macwhisper-mcp-server). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 20 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability75
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 878 tokens (~125/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
cancel_transcription Cancel Transcription ~18
Cancel the currently running transcription, if any.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
get_watch_results Get Watch Results ~41
Return completed watch-folder transcriptions and clear the queue. Each entry contains: ``file``, ``transcript``, ``destination``, ``error``.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
list_allowed_paths List Allowed Paths ~21
Return the directories this server is allowed to read audio from.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
list_models List Models ~155
Return the transcription models available across all engines. MacWhisper entries are formatted as ``engine:model-id — Display Name [active]`` where ``[active]`` marks the model currently selected in MacWhisper; pass the ``engine:model-id`` string as ``model`` with the default ``engine="macwhisper"``. whisper-cpp entries (if ``MACWHISPER_WHISPERCPP_MODEL_DIR`` is configured) are formatted as ``filename [whisper-cpp]``; pass the filename as ``model`` with ``engine="whisper-cpp"``. Requires the MacWhisper CLI to be reachable even if you only intend to use the whisper-cpp engine.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
start_watch Start Watch ~129
Start watching a folder for new audio files to auto-transcribe. New audio files dropped into ``folder`` are transcribed automatically and moved to a "done" directory. By default this is ``<folder>/../done``; override it with the ``MACWHISPER_WATCH_DONE_DIR`` env var. Both the incoming folder and the done directory must be inside the configured allow-list, otherwise the call is rejected. Call ``get_watch_results()`` to retrieve completed transcriptions.
| Name | Type | Req | Description |
|---|---|---|---|
| folder | string | yes | Absolute or ``~``-prefixed path to the incoming directory. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |

stop_watch Stop Watch ~14
Stop the active folder watcher.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
transcribe_audio Transcribe Audio ~500
Transcribe a local audio file and return the transcript. IMPORTANT: ``path`` must be a file on the user's Mac filesystem inside the configured allow-list (typically ~/Desktop or ~/Downloads). Files uploaded to the Claude chat window are NOT accessible — ask the user to save the file to their Desktop or Downloads folder first. If this tool returns an access-denied error, do NOT attempt to transcribe the file by any other means (e.g. downloading a model, calling an external API, or using in-process speech recognition). Simply tell the user to save the file locally and retry with this tool.
| Name | Type | Req | Description |

| engine | string | – | "macwhisper" (default) — routes through the MacWhisper CLI, or "whisper-cpp" — an independent local backend that does not use MacWhisper at all. Requires whisper-cpp installed (`brew install whisper-… |
| language | – | – | Optional ISO 639-1 code (e.g. "da", "de") or "auto" to force the transcription language. If omitted, a per-directory default is used when the file's folder matches one configured in MACWHISPER_LANGUA… |
| model | – | – | Optional model override. For the default ``engine="macwhisper"``, an engine:model-id string, e.g. "whisperkit:openai_whisper-large-v3-v20240930" — use ``list_models()`` to see what is installed. For… |
| path | string | yes | Absolute or ``~``-prefixed path to an audio file on the local Mac filesystem inside the configured allow-list. Supported formats: m4a, mp3, mp4, mov, wav, aiff, flac (whisper-cpp engine only: wav, mp… |
