NeverBounce Email Validator

Example Use Cases

• 1

  Verify whether a single email address is deliverable before sending transactional email.

• 2

  Perform batch or pre-send list cleaning to reduce bounce rates and improve sender reputation.

• 3

  Validate user-supplied emails in real-time (e.g., signup or checkout flows) to prevent invalid addresses.

Description

This Model Context Protocol (MCP) server wraps the NeverBounce email validation API to provide email verification capabilities to MCP clients. It exposes a tool (neverbounce_validate_email) to check if an address is valid, deliverable, and safe to send to. The server can be run locally or via Docker and requires a NEVERBOUNCE_API_KEY to operate, enabling agents to perform real-time or batch email hygiene checks before sending messages.
