EmailMCP (tuoc1226-maker/EmailMCP) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: there is no public source to read and no endpoint we can reach, so there is nothing for us to inspect. No publisher has claimed this listing.
Enables unified email management across Gmail, Outlook, iCloud, and IMAP providers with tools for search, send, organize, and batch operations via natural language.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
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
Nodemailer: Improper TLS Certificate Validation in OAuth2 Token Fetch Enables Credential Interception
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
25/25 tools missing one or more hints — email_list_accounts (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); email_add_account (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); email_remove_account (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +22 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.
Shell command execution
1 child_process/subprocess call in production code — runs shell commands (src/setup/wizard.ts:30)
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@8.0.0 (high), nodemailer@8.0.0 (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.
Domain consistency
npm scope @marlinjai doesn't match GitHub owner tuoc1226-maker
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
