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

GMAIL_CREDENTIALS_PATHe "=/gmail-server/credentials.json" \GMAIL_OAUTH_PATHe =/gcp-oauth.keys.json \All four hints declared on every tool
24/24 tools missing one or more hints — read_email (missing: destructiveHint, idempotentHint, openWorldHint); search_emails (missing: destructiveHint, idempotentHint, openWorldHint); download_attachment (missing: destructiveHint, idempotentHint, openWorldHint), +21 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 5/24 tools referenced in tests (21%)
Write tests that reference each tool by name so every tool has at least one test.
