The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
extract-zip allows arbitrary file writes through symlink archive entries
extract-zip unvalidated symlink path traversal
Electron: Use-after-free in offscreen child window paint callback
Electron: Use-after-free in WebContents fullscreen, pointer-lock, and keyboard-lock permission callbacks
Electron: Sandboxed iframe can bypass the allow-popups restriction via the OpenURL navigation path
COMSPECQSERIAL_MOCK_MARKETSHELLTool 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
57/57 tools missing one or more hints — conn.list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); conn.data.write (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); conn.data.write_hex (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +54 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
Only 10/57 tools referenced in tests (18%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
6 calls in production code run through a shell (src/services/connection/pty.ts:50, src/services/connection/pty.ts:70, src/services/nfs/manager.ts:73)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 2 high severity in production deps — extract-zip@2.0.1 (high), extract-zip@2.0.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
7 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
3/9 production deps abandoned (no release in 2+ years): tftp@2022-06-27 (4.2y), extract-zip@2023-03-04 (3.5y), ftp-srv@2023-10-09 (2.9y)
Domain consistency
npm scope @qserial doesn't match GitHub owner qiuchengcai
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
