Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
Nodemailer: Message-level raw option bypasses disableFileAccess/disableUrlAccess, enabling arbitrary file read and full-response SSRF in the delivered message
Nodemailer’s addressparser is vulnerable to DoS caused by recursive calls
Nodemailer: Email to an unintended domain can occur due to Interpretation Conflict
Nodemailer: CRLF injection in Nodemailer List-* header comments allows arbitrary message header injection
GMAIL_CREDENTIALS_PATHe "=/gmail-server/credentials.json" \GMAIL_OAUTH_PATHe =/gcp-oauth.keys.json \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
19/19 tools missing one or more hints — send_email (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); draft_email (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); read_email (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +16 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.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@0.4.0 (high), nodemailer@7.0.3 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Domain consistency
npm scope @gongrzhe doesn't match GitHub owner tekupdk
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
