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.
When Vitest UI server is listening, arbitrary file can be read and executed
Nodemailer: Message-level raw option bypasses disableFileAccess/disableUrlAccess, enabling arbitrary file read and full-response SSRF in the delivered message
Nodemailer: CRLF injection in Nodemailer List-* header comments allows arbitrary message header injection
Nodemailer has SMTP command injection due to unsanitized `envelope.size` parameter

49/49 tools missing one or more hints — list_accounts (missing: idempotentHint, openWorldHint); get_email_stats (missing: idempotentHint, openWorldHint); download_attachment (missing: idempotentHint, openWorldHint), +46 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 annotations match behaviour
1 read-only tool performs write/delete/exec — analyze_email_for_scheduling (line 644: REMINDER_KEYWORDS.exec(combined))
Either remove the readOnlyHint:true annotation, or remove the write/delete call from the tool handler.
Tool test coverage
25/49 tools referenced in tests (51%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
22 child_process/subprocess calls in production code — runs shell commands (src/cli/scheduler.ts:136, src/cli/scheduler.ts:149, src/cli/scheduler.ts:157)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 1 high severity in production deps — nodemailer@8.0.1 (high), nodemailer@8.0.1 (low)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
