About MailVeri MCP
Key Strengths
- Open MCP server (uvx from GitHub) exposing MailVeri’s verify, balance, bulk batch, status, download and delete tools to Claude, Cursor, Codex, Windsurf, VS Code/Cline and more
- Single-email verification covers SMTP, catch-all, disposable and role detection; bulk jobs return downloadable ZIP/CSV results
- MailVeri account side: up to 1,000 free credits on signup, credits never expire, and pay-as-you-go packs from $9 / 10k credits
Limitations to Consider
- Needs a MailVeri API key and uv/uvx installed; misconfigured paths break desktop clients
- Single verify is rate-limited (~1 req/s); large lists must use batch tools
- MCP repo is brand-new with essentially no GitHub stars; you still pay MailVeri per verification credit
