## 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 2026-09-20.

- **Supply Chain Security**: 13/100
  - Malware scan not yet available for this package.
  - 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.
  - No install/post-install scripts declared.
  - 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.
- **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 23 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 53/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 2969 tokens (~56/item across 53 items; 53 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 80/100
  - Stability observed for 24 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 5 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.
  - An AI judge read all 53 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100

## Common questions

### What is the EvoBurrow MCP server?

EvoBurrow MCP is listed in the public MCP registry as io.github.daredoole/evoburrow-mcp. Unofficial guarded A1 Evo AcoustiX, REW, and Denon/Marantz calibration tools. This page covers its MCPB bundle (https://github.com/daredoole/evoburrow-mcp/releases/download/v2.0.0-beta.1/evoburrow-mcp-2.0.0-beta.1.mcpb).

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

EvoBurrow 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 EvoBurrow MCP server expose?

EvoBurrow MCP exposes 53 tools: rew_install_discover, rew_launch_plan, rew_launch_execute, rew_capability_negotiate, a1_workspace_scan, and 48 more. Their descriptions and schemas cost roughly 2,969 tokens of context every time the server is loaded.

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

EvoBurrow 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.
