Show HN: I made a guardrail against AI outreach slop (API/MCP)

MailDignity is an API and MCP tool that checks LLM-generated cold emails before sending, flagging issues like generic flattery, fake familiarity, unsolicited diagnoses and asymmetric asks. It returns PASS, REVIEW (with a repaired_body) or FAIL verdicts, and works with Gmail, Outlook, ChatGPT, Claude, Cursor and no-code stacks. Pricing starts at $19/mo for 2,000 checks with a 7-day free trial.
