Email Triage Agent

Deterministic email triage for Hermes Agent. It classifies messages into P0–P3 or REVIEW, emits the shared pif.event.v1 contract, and lets Hermes deliver the result through its existing Feishu gateway.

确定性的 Hermes 邮件分诊 MCP：不确定就保留，V1 永不删除、永不发信，飞书凭证继续由 Hermes 管理。

Why / 设计理念

• Reduce information, do not create more of it.
• P0 is immediate; P1 waits for a digest; P2/P3 are audit-only.
• Sender-auth conflicts and low confidence become REVIEW/HOLD.
• Human feedback updates an external JSONL rule trail, never model weights.
• The optional adapter connects to real mailboxes with read-only IMAP. It never executes Delete, Send, Move, or Seen changes.

Local run

npm ci
npm test
npm run demo

Real mailbox adapter commands:

node src/adapter-cli.js test --account qq-main
node src/adapter-cli.js poll --accounts qq-main

Credentials are references to macOS Keychain items or environment variables; literal passwords and tokens are rejected by config validation. See the read-only mailbox adapter guide.

One-off classification:

node src/cli.js --json '{"sender":"no-reply@accounts.google.com","subject":"New login detected","auth":{"spf":"pass","dkim":"pass","dmarc":"pass"},"protectedSender":true}'

Add to Hermes on macOS

Hermes discovers stdio MCP tools from ~/.hermes/config.yaml. Clone and install, then use an absolute path:

git clone https://github.com/roclee2692/email-triage-agent.git ~/Projects/email-triage-agent
cd ~/Projects/email-triage-agent && npm ci
hermes mcp add email-firewall --command node --args "$HOME/Projects/email-triage-agent/src/mcp.js"
hermes mcp test email-firewall

Hermes registers tools with names such as mcp_email_firewall_triage_email. The server never needs Feishu secrets: Hermes already owns the Feishu channel and presents or schedules the returned message.

Tools

• triage_email
• render_feishu_email
• record_email_feedback
• get_email_policy
• poll_email_accounts
• test_email_account
• acknowledge_email_events

The companion repository is crypto-market-sentinel. Both return the same event envelope, so one Hermes prompt can apply the same urgent/digest/audit policy.
