RadMail MCP — Integration Guide

The email operating system for AI agents. RadMail searches your real inbox, surfaces a "Right Now" lane, tracks commitments, and drafts reviewable replies — all through MCP. No tool can auto-send money, change banking, or make irreversible decisions without human approval.

What It Does

RadMail turns your email inbox into an MCP-accessible data source with agent-native controls. Unlike basic email MCP servers that just read/write, RadMail adds intelligence layers:

  1. Smart Inbox Search — Search by sender, subject, content with relevance ranking
  2. "Right Now" Lane — AI-prioritized view of emails needing immediate attention
  3. Commitment Tracking — Detects promises, deadlines, and action items from email threads
  4. Draft Replies — Generates reviewable draft responses (never auto-sends)
  5. Safety Gating — Financial actions, banking, and irreversible operations require explicit human approval

Key Capabilities

  • Search — Ranked inbox search by sender, subject, content, date range
  • Prioritization — AI-curated "Right Now" lane for urgent/important emails
  • Commitment Extraction — Automatically detects and tracks commitments and deadlines
  • Draft Generation — Creates reviewable reply drafts with context from thread history
  • Safety Guardrails — Blocks auto-send for financial/banking/irreversible actions

CorpusIQ Use Cases

1. Morning Email Triage

"Show me my Right Now lane and summarize any new commitments or 
deadlines from overnight emails."
The agent surfaces urgent emails, extracts commitments, and presents a prioritized action list.

2. Client Follow-Up

"Find all emails from Acme Corp in the last 2 weeks. Did I promise 
anything I haven't delivered? Draft follow-ups for each open thread."
Searches sender history, cross-references commitments, drafts replies.

3. Weekly Digest

"Summarize all unresolved email threads from this week, grouped by 
sender, with action items I haven't completed."
Generates a weekly accountability report from inbox data.

Operator Value

Use Case Time Saved Safety Benefit
Morning triage 20-30 min/day Never misses urgent items
Commitment tracking Eliminates forgotten promises All deadlines surfaced
Draft replies 5-10 min per email Human reviews before sending

Prerequisites

  • Email account with IMAP/OAuth access
  • RadMail authentication token
  • MCP client (Claude Desktop, Cursor, Hermes)

Troubleshooting

Issue Fix
Can't connect to inbox Verify email credentials and IMAP/OAuth setup
Search returns no results Check date range and search terms; ensure inbox is accessible
Drafts look generic Provide more context in prompts; specify tone and key points

Safety Note

RadMail's core design principle: no irreversible action without human approval. The agent can read, search, and draft — but sending, financial transactions, and account changes require explicit human confirmation. This makes it safe for production business use.
