Radmail MCP Overview

radmail-ai/radmail-mcp MCP server provides agent tools for email search, triage, commitment tracking, explainable prioritization, and draft replies. It runs as a zero-auth hosted sandbox or locally through the npm package, while connected inbox features use a RadMail API key and remain read-only. Deterministic hard stops keep money, banking changes, first-contact, decisions, and prompt-injection cases human-only. Reach for it when an agent needs to organize email work without giving the agent a send capability.
