Package trust score
This server scores 50/100 (grade C). The biggest gaps are supply chain and attack history — fixing those will raise your score fastest. Evidence is partial (0% coverage): Behavioral deep-scan produced no runtime data (install/egress hook unavailable). Lower coverage caps the score — re-run with runtime layers enabled for a stronger grade. Top recommendation: switch to a trusted publisher package and enable dependency verification (+~6 pts).

Fix the issues above, then run a deep scan or publish from your mastyf.ai proxy for a maintainer-verified badge.
Trust score: 50/100 (live scan)
No known CVEs
Unknown publisher
Malware/supply-chain heuristics raised flags — review the signals before trusting this package.
Supply-chain signals need review — verify package name and publisher before trusting.
Only basic API-key auth is configured. OAuth or mTLS is stronger for production.
Uses local stdio transport (low network exposure) but no wire encryption if exposed remotely.
Some tools can modify data or run sensitive operations — tighten policy around them.
No attack data observed — static review only or no probe coverage.
Tool responses are not scanned for leaked secrets or PII — enable Response DLP.
Not proxied through Mastyf AI — no runtime policy enforcement or audit trail.
Plain-language findings from the security scan — fix these to improve your score.
The scan produced evidence from 0% of its runtime layers. Behavioral deep-scan produced no runtime data (install/egress hook unavailable) — so the differentiated runtime checks could not be verified and the score is capped until they run.
How to fix: Re-run the scan with a reachable live server and a successful behavioral install so egress and attack-probe layers produce data.
Advisory GHSA-mh29-5h37-fv8m affects js-yaml in the exact dependency tree resolved for this package. This affects js-yaml (direct dependency) and is reported by exact-tree npm audit.
How to fix: No automated fix is available from npm — pin a patched version manually or replace the package.

The server accepts tool calls without verifying who is calling. In shared or remote setups, attackers could invoke file or system tools directly.
How to fix: Add OAuth 2.1, API keys, or mTLS before exposing this server beyond localhost.
The server talks over local stdin/stdout — low network risk when run on the same machine, but no encryption if tunneled remotely.
How to fix: Keep stdio for local dev; use HTTPS/mTLS or Mastyf AI proxy for remote agents.
The runtime probe tried to start the server and probe it with attack payloads, but could not establish a live MCP connection: Process exited with code 1. No attack observations were collected.
How to fix: Confirm the package starts an MCP server (some expose it behind a subcommand) and re-run a live probe.
