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:
- Smart Inbox Search - Search by sender, subject, content with relevance ranking
- "Right Now" Lane - AI-prioritized view of emails needing immediate attention
- Commitment Tracking - Detects promises, deadlines, and action items from email threads
- Draft Replies - Generates reviewable draft responses (never auto-sends)
- 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."
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."
3. Weekly Digest¶
"Summarize all unresolved email threads from this week, grouped by
sender, with action items I haven't completed."
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.

Integration with CorpusIQ¶
CorpusIQ is the connector layer that lets AI assistants read the systems a business already runs on - accounting, payments, CRM, email, files and analytics - and answer with the source named. It is read-only by design: it retrieves data and never writes to, or acts in, a connected system, which is what makes it safe to point at live accounts.
This page is part of the CorpusIQ directory, the reference we maintain for the MCP server and agent-skill ecosystem. Run alongside CorpusIQ, a third-party server like this one can be combined with a company's own business data in a single answer.
