Email-deliverability tools for AI agents — 12 MCP tools across email verification, DNSBL across 50 zones, SPF/DKIM/DMARC analysis, spam-trap heuristic scoring, domain intelligence, and email finder. Free tier with no credit card. MIT licensed. Drops into Claude Desktop and Cursor via npx.

A hosted, read-only Model Context Protocol server that gives an AI voice agent phone intelligence in one call — who is this inbound caller, and is this number one to think twice about — before it burns agent minutes. Four read-only tools: phone_lookup (validity, line type, range carrier, country, CNAM where available, STIR/SHAKEN verstat, a labeled spam signal, a first-party do-not-contact signal, and a signed receipt), caller_risk, line_type, and dnc_check. Every billable answer carries an Ed25519-signed receipt — verifiable 'checked as of T' evidence — and no raw phone number is ever stored (hashed only). Remote/hosted: nothing to install; point your agent at the URL.
