Install from
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.
Electron: Use-after-free in offscreen child window paint callback
Electron: Sandboxed iframe can bypass the allow-popups restriction via the OpenURL navigation path
Electron: Context isolation bypass via Function.prototype.bind hijack
Electron: Custom protocol with supportFetchAPI but not corsEnabled allows cross-origin reads
Electron: DevTools JavaScript Injection via Unsanitized Dock State Parameter

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
7/7 tools missing one or more hints — read_file (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_files (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_files (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 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 0/7 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
1 call in production code run through a shell (server/providers/localtools.ts:203)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Dev dependencies
4 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
