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 Security24
- 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.Unverified
- Known CVEs were checked across the 131 of 131 dependencies we could resolve, so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- 34 of 131 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency48
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 17 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability72
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management57
- Stability observed for 17 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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 →
prepare_speech_model Prepare the speech model ~47
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
search_dictations Search Yap dictations ~128
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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. |
No output schema declared.
No examples provided.
transcribe_audio Transcribe audio ~209
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | 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. |
No output schema declared.
No examples provided.
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.

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.
