About MailerCheck MCP Server
Connect your MailerCheck account to any AI agent to automate your email hygiene and deliverability workflows. This MCP server enables your agent to verify single email addresses instantly, manage batch verification lists, and monitor your account credits directly from natural language interfaces.
Windsurf's Cascade agent chains multiple MailerCheck tool calls autonomously. query data, analyze results, and generate code in a single agentic session. Paste Vinkius Edge URL, reload, and all 5 tools are immediately available. Real-time tool feedback appears inline, so you see API responses directly in your editor.
What you can do
- Real-time Verification — Instantly check if an email address is valid, risky, or invalid before sending
- Batch Processing — Upload large lists of emails for asynchronous validation and track their progress
- Results Ingestion — Retrieve detailed status reports for completed batches, including reason codes for invalid emails
- History Oversight — List all recent verification batches and retrieve their technical metadata
- Account Auditing — Monitor your authenticated user details and remaining verification credits
