// 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.
configBASE_DIRSet to that directory. It is also the security boundary for file operations. Replace
configBASE_DIRSN/A (unset) JSON array of document roots; takes precedence over BASE_DIR
configCACHE_DIRcache-dir ./models/ Model cache directory
configCHUNK_MIN_LENGTHchunk-min-length 50 Minimum chunk length in characters (1–10000)
configCODEX_HOME
configDB_PATHsame directory so they use the same default index, or set BASE_DIR and explicitly.
configHF_MODEL_REVISION
configMAX_FILE_SIZEmax-file-size 104857600 (100MB) Maximum file size in bytes
configMODEL_NAMEboth interfaces should share an index. In particular, and the CLI --model-name
configRAG_DEVICEN/A cpu ONNX Runtime execution device
configRAG_DTYPEN/A fp32 Embedding dtype supplied by the selected model

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

18/18 tools missing one or more hints — query_documents (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ingest_file (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ingest_data (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +15 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

6/18 tools referenced in tests (33%)

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

Claim the listing to review these findings one by one and send us a correction where you disagree, straight to the team. Claiming also means we tell you when the grade moves, and reach you first if we find anything urgent.

// 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 3 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
