How to Use the No2Bounce MCP in Cursor
Validate your user sign-up lists and check bounce rates directly inside Cursor.
Works with every AI agent you already use
…and any MCP-compatible client
Connect No2Bounce MCP to Cursor
Create your Vinkius account to connect No2Bounce to Cursor and route execution through our secure gateway. The platform manages server hosting, runtime updates, and security layers. Configuration requires no manual server provisioning.
Clean database exports directly in Cursor
Trigger `validate_bulk` directly in Cursor when refactoring database schemas or writing migration scripts. Your agent cleans your mock data or production exports without you ever leaving the editor. The agent processes the list and updates your JSON files or SQL seeds with valid addresses only. You avoid writing custom validation scripts because the editor handles the API calls for you.
Debug sign-up flows with this MCP Server
Run `get_validation_status` from the Cursor chat to troubleshoot why a specific address is bouncing. Your agent inspects the deliverability metrics immediately alongside your active codebase. You get instant feedback on deliverability metrics directly alongside your codebase. This helps you determine if the issue lies with your SMTP settings or if the user simply mistyped their domain.
Generate clean seed data for local testing
Use `validate_bulk` to generate clean seed data for your local testing environments. Your agent validates your test suites before you run integration tests, keeping bad domains out of your database. This keeps your local development environment clean. Your test suites run faster, and you avoid polluting your analytics with fake bounces.
