MCP server for email deliverability: validate SPF/DKIM/DMARC/BIMI, check blacklists, test SMTP/IMAP, look up DNS, and generate ready-to-deploy records for any major email provider. Ships with two one-click prompts (audit-deliverability, setup-dns). Public, no auth.

Enables AI agents to create and use temporary email and SMS inboxes, check messages, and wait for or extract OTPs and verification links during account registration. Combines both channels through a unified OTP tool while redacting sensitive tokens in audit logs.

FastMCP server exposing the full operational surface of the Apollo.io REST API to AI assistants. Provides 27 tools for outbound sales automation including campaign health, sequence management, mailbox warmup, CRM operations, and programmatic template/sequence editing with audit logging.
