// key findings
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.
configMCP_MAX_RESPONSE_SIZEMaximum response size in bytes (default: 50000)
configMCP_MAX_ITEMS_PER_PAGEDefault items per page (default: 20)
configMCP_MAX_TEXT_LENGTHMaximum text length before summarization (default: 10000)
configMCP_MAX_LINESMaximum lines before summarization (default: 500)

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

15/15 tools missing one or more hints — handle_call_tool (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_artifacts (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); analyze_jar (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +12 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool test coverage

10/15 tools referenced in tests (67%)

Write tests that reference each tool by name so every tool has at least one test.

Shell command execution

2 calls in production code run through a shell (bin/maven-decoder-mcp.js:25, bin/maven-decoder-mcp.js:49)

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

No arbitrary install scripts

Has postinstall/preinstall script — runs arbitrary code on npm install

Remove postinstall/preinstall hooks unless they’re essential.

Dependency freshness

2/3 production deps stale: child_process@2022-06-13 (4.2y), path@2023-05-20 (3.3y)

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
