About
Gmail messages, threads, labels, drafts and sending, as MCP tools via the Gmail API.
Security Report
mailport is a clean-role Gmail MCP server that uses a user-supplied bearer token from GOOGLE_ACCESS_TOKEN and has no hardcoded secrets, shell execution, or exfiltration patterns. The main concerns are that to, cc, bcc and subject are concatenated into RFC822 headers without stripping CR/LF, allowing header injection in send and draft tools, and that GMAIL_API_URL can redirect the bearer token to an arbitrary host. Email sending is inherently high-impact, but it matches the server's stated purpose. Supply chain analysis found 4 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.

mailport
Gmail messages, threads and labels as MCP tools, talking to the Gmail API. mailport is a clean-room rebuild of the core surface of the Gmail reference MCP server, under a new name: fresh code written from the public Gmail API documentation, no copied branding.
Tools (core subset, 10)
list_messages, get_message, list_threads, get_thread,
list_labels, send_message, create_draft, modify_message,
trash_message, create_label.
Label update/delete, draft get/update/delete/send, message delete and batchModify, history, profile/settings/watch, and attachment downloads from the wider Gmail surface are not in this subset.
Setup
Set a Google OAuth access token:
export GOOGLE_ACCESS_TOKEN=ya29....
Optionally override the API base with GMAIL_API_URL
(default https://gmail.googleapis.com/gmail/v1). Without the token,
every tool call fails with an error naming the missing variable.
CLI
npx @reneturcios/mailport list_messages '{"query":"in:inbox","max_results":5}'
npx @reneturcios/mailport mcp # stdio MCP server
Each tool name is a subcommand taking one JSON object argument.
