Available components
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 Security13
- Malware scan not yet available for this package.Unverified
- Known CVEs could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.Unverified
- No install/post-install scripts declared.Pass
- Dependency health could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.Unverified
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 23 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability55
- AI-judged instruction clarity (fair).Partial
- Tool/resource definitions use about 6297 tokens (~60/item across 104 items; 104 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management80
- Stability observed for 24 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 21 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "rew_launch_execute" implies "execute" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 104 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

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

Background: How many MCP packages publish verified provenance →
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 →

What is the Audio Calibration MCP server?
Audio Calibration MCP is listed in the public MCP registry as io.github.daredoole/audio-calibration-mcp. Evidence-bound REW measurement, analysis, conservative EQ, DSP, and listening-test tools. This page covers its MCPB bundle (https://github.com/daredoole/audio-calibration-mcp/releases/download/v0.2.0-beta.1/audio-calibration-mcp-0.2.0-beta.1.m…).
Is the Audio Calibration MCP server safe to use?
Audio Calibration MCP scores 48 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 Audio Calibration MCP server expose?
Audio Calibration MCP exposes 104 tools: audio_job_status, audio_job_cancel, audio_doctor, rew_install_discover, rew_launch_plan, and 99 more. Their descriptions and schemas cost roughly 6,297 tokens of context every time the server is loaded.
What licence is the Audio Calibration MCP server under?
Audio Calibration MCP declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
