"OSF" matching MCP servers:

Enables AI coding clients to inspect and invoke local-only tools for an evidence-gated outbound workflow, including buyer selection, mailbox verification, deduplication, factual preflight, and approval-hash checks, with sending disabled by default. It supports synthetic demos and dry-run transports without mailbox credentials, while requiring explicit authorization before any live email action.

Enables assessing and comparing domains for email spoofing risk by evaluating SPF, DMARC, MX, and DKIM records from public DNS, providing A-F grades and concrete remediation steps.

An enterprise-grade MCP server that provides production-ready IMAP email integration with advanced reliability features, comprehensive monitoring, and secure account management.

Enables MCP clients to exchange an MCP-audience token for a Microsoft Graph token and call Graph as the signed-in user, with tools for identity verification and recent mail access.

Enables coding agents to research and score leads against industry ICP templates, draft cold emails, and gate every draft through CAN-SPAM and deliverability checks before a human approves it. Nothing is sent by default, and each step is recorded in an append-only audit log showing why a lead was contacted.
