## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 24/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs were checked across the 131 of 131 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - 34 of 131 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 48/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 17 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 425 tokens (~141/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 57/100
  - Stability observed for 17 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Install

### How do I install the Yap MCP server?

Yap ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, 4d31be493d1fdc5b0be49a40777951bf05a9bd307a4db3e4956758b5de043ad6; the commands to do that are on this page. If it does not match, do not open it.

## MCP tools (3)

### `transcribe_audio` (~209 tokens)

Transcribe audio

Transcribe a local audio or video file to text, entirely on this computer with the NVIDIA Parakeet speech model (no upload, no API key). Handles WAV, MP3, M4A, MP4, FLAC, OGG, Opus, WebM, AIFF and more, any length, and detects the language automatically among 25 European languages (English, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Russian, Ukrainian, Swedish and others). Use it for voice memos, meeting and interview recordings, lectures and podcasts.

Input parameters:

- `clean` (boolean): Tidy the text the way the Yap app does: capitalization, final punctuation, and English hesitations such as "um" removed. Default true.
- `path` (string, required): Absolute path of the audio or video file on this computer (a leading ~ is allowed).
- `timestamps` (boolean): Prefix each passage with its start time, e.g. [1:05]. Default false.

### `search_dictations` (~128 tokens)

Search Yap dictations

Search what the user dictated with the Yap app (yapapp.cc) on this computer: the history Yap keeps locally. Returns the matching dictations, newest first, with their time. Use it when the user refers to something they said or dictated earlier. The returned text is shared with this assistant.

Input parameters:

- `days` (integer): How many days back to look. Default 7.
- `limit` (integer): Maximum number of dictations. Default 20.
- `query` (string): Words to look for (all must appear). Omit to list the most recent dictations.

### `prepare_speech_model` (~47 tokens)

Prepare the speech model

Download and verify the on-device speech model ahead of the first transcription (about 670 MB, once), or report its status. Optional: transcribe_audio does this on its own.

## Common questions

### What is the Yap MCP server?

Yap is an MCP server listed in the public MCP registry as cc.yapapp/yap. Private on-device speech to text: transcribe audio files and search your Yap dictations. No upload. This page covers its MCPB bundle (https://github.com/founden-bot/yap-mcp/releases/download/v1.0.0/yap.mcpb).

### Is the Yap MCP server safe to use?

Yap scores 56 out of 100 on VerifyMCP. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Yap MCP server expose?

Yap exposes 3 tools: transcribe_audio, search_dictations, prepare_speech_model. Their descriptions and schemas cost roughly 384 tokens of context every time the server is loaded.

### What licence is the Yap MCP server under?

Yap declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
