"Stack Exchange" matching MCP connectors:

See how often any e-commerce brand sends marketing emails: counts, send dates and recent subject lines for 750+ brands, mostly in the Nordics and Germany. Read-only, no login.

Let AI agents check whether an email is a real person's work address or a personal, disposable, relay or shared team inbox (info@, sales@, support@), and see which stack the company runs: Google Workspace or Microsoft 365 with tenant ID and identity provider. Every verdict comes with reason codes and an allow / review / block recommendation. Docs: https://isbusinessemail.com/docs/mcp

Free quote and late-fee calculators, paid reminder emails and a $1 small-business tool stack report.

Domain intel for AI agents: RDAP registration, DNS, email deliverability, tech stack.
