Ask your AI agent "Verify if the email 'test@example.com' is valid." and get the answer without opening a single dashboard. With 10 tools connected to real NeverBounce data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.
Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by the Vinkius - your credentials never touch the AI model, every request is auditable. Connect in under two minutes.

Your AI agents only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure and security, zero maintenance.

Frequently asked questions about the NeverBounce MCP Server
Where do I find my NeverBounce API Key?
Log in to your NeverBounce dashboard and navigate to the API section to create or copy your 'Secret Key'.
What do the different result statuses mean?
'Valid' means the email is safe to send. 'Invalid' will bounce. 'Disposable' are temporary addresses, and 'Catchall' means the domain accepts all mail, making deliverability uncertain.
How do I start a bulk verification job?
First, use create_job_from_url or create_job_from_input. Then, call parse_job followed by start_job to begin the verification process.
