AgenticMail is a self-hosted communication platform purpose-built for AI agents. It runs a local Stalwart mail server via Docker, integrates Google Voice for SMS/phone access, exposes a REST API with 75+ endpoints, and works with any MCP-compatible AI client and OpenClaw via plugin. Each agent gets its own email address, phone number, inbox, and API key.

Why 🎀 AgenticMail?

AI agents need to communicate with the real world. Email is the universal communication protocol — every person and business has an email address. AgenticMail bridges the gap between AI agents and email by providing:

• Isolated mailboxes — each agent has its own email address, inbox, and credentials. Agents can't read each other's mail.
• Internet email connectivity — two gateway modes to send/receive real email (Gmail relay or custom domain with DKIM/SPF/DMARC).
• Security guardrails — outbound scanning prevents agents from leaking API keys, passwords, or PII. Blocked emails require human approval.
• Agent collaboration — agents can email each other, assign tasks, and make synchronous RPC calls.
• SMS / Phone number access — integrate Google Voice for SMS receive/send, verification code extraction, and phone number access for AI agents.
• Smart orchestration — call_agent replaces basic sub-agent spawning with auto mode detection, dynamic timeouts, runtime tool discovery, and async execution for long-running tasks.
• Tool integrations — 62 MCP tools for any AI client, 63 OpenClaw tools, and a 44-command interactive shell.
• Self-updating — agenticmail update checks npm, verifies OpenClaw compatibility, and updates both packages automatically.

Features

Email Operations

• Send email with text, HTML, attachments, CC/BCC, reply-to, and custom headers
• Receive email via IMAP with real-time SSE event streaming (IMAP IDLE)
• Reply and forward with proper In-Reply-To and References headers for threading
• Search by sender, subject, body text, date range, read/unread status
• Folders — create, list, move messages between folders
• Batch operations — mark read/unread, delete, move multiple messages at once
• Drafts — save, edit, and send draft emails
• Templates — reusable email templates with variable substitution
• Scheduled sending — queue emails for future delivery
• Signatures — per-agent email signatures
• Tags — label and categorize messages
• Contacts — manage address book per agent

Multi-Agent

• Account management — create, list, delete agents with unique email addresses
• Agent-to-agent email — agents can email each other directly via @localhost
• Task system — assign tasks to agents, claim, submit results, track status
• RPC calls — synchronous agent-to-agent calls with timeout (long-poll + SSE notification)
• Agent directory — discover other agents by name

Gateway (Internet Email)

• Relay mode (beginner) — use your existing Gmail or Outlook as a relay. Emails appear as you+agentname@gmail.com. Setup takes 2 minutes.
• Domain mode (advanced) — custom domain via Cloudflare. Agents send from agent@yourdomain.com with full DKIM signing, SPF, and DMARC records.
  • Automatic DNS configuration (MX, SPF, DKIM TXT, DMARC, tunnel CNAME)
  • Cloudflare Tunnel for secure inbound traffic without exposing ports
  • Cloudflare Email Worker for Email Routing (catch-all → worker → AgenticMail)
  • Optional Gmail SMTP outbound relay for residential IPs without PTR records
  • Domain purchase via Cloudflare Registrar
  • DNS backup before any modifications
  • Automatic @domain email alias for all existing agents

Security

• Outbound guard — scans every outgoing email for sensitive data patterns:
  • API keys and tokens (AWS, OpenAI, Stripe, GitHub, etc.)
  • Passwords and credentials
  • Private keys (SSH, PGP, RSA)
  • PII patterns (SSN, credit card numbers)
  • Internal URLs and configuration data
  • Blocked emails are held for human-only approval (agents cannot self-approve)
• Spam filter — rule-based scoring engine for inbound email:
  • Categories: phishing, scam, malware, commercial spam, social engineering, lottery scam
  • Configurable threshold (default: 40)
  • Skips internal agent-to-agent emails
  • Runs on both relay inbound and SSE event streams
• Human-only approval flow — when an agent's email is blocked:
  • The agent is informed the email was blocked and told to notify their owner
  • The owner receives a notification email with full blocked email content, warnings, and pending ID
  • Only the master key holder can approve or reject (POST /mail/pending/:id/approve)
  • Agents can list and view their own pending emails but cannot approve or reject them
  • System prompt guidelines instruct agents to inform their owner and wait, never attempt to bypass
• DKIM/SPF/DMARC — automatic DNS setup in domain mode for email authentication
• Rate limiting — configurable per-endpoint rate limits

SMS / Phone Number Access

• Google Voice integration — give agents a real phone number via Google Voice
• Direct Voice web reading (primary, instant) — reads SMS directly from voice.google.com via browser
• Email forwarding (fallback) — Google Voice forwards SMS to email, agent auto-detects and records them during relay polling
• Separate Gmail polling — for users whose GV Gmail differs from relay email, runs a dedicated IMAP poll
• Verification codes — automatic extraction of OTP/verification codes from SMS (4-8 digit, alphanumeric, Google G-codes)
• Send SMS — record outbound messages, send via Google Voice web automation
• Smart setup wizard — validates Gmail/GV email matching, warns about mismatches, collects separate credentials when needed

Smart Orchestration (call_agent)

• Auto mode detection — reads task complexity, picks light/standard/full mode automatically
• Dynamic timeouts — 60s for quick tasks, 5+ minutes for deep research, 1 hour for async
• Runtime tool discovery — probes host config for available tools instead of static deny lists
• Async execution — long-running tasks run independently, auto-compact context, email results when done
• Structured RPC — sub-agents return JSON, not raw text

Integrations

• MCP server — 62 tools for any MCP-compatible AI client
• OpenClaw plugin — 63 tools with skill definition and system prompt guidelines
• REST API — 75+ endpoints, OpenAPI-style, Bearer token auth
• SSE events — real-time inbox notifications via Server-Sent Events
• Interactive CLI — 44 shell commands with arrow key navigation, body previews, retry logic
• Self-updating — agenticmail update or /update in shell, with OpenClaw compatibility check

Data Flow

Sending email (relay mode):

1. Agent calls POST /mail/send with recipient, subject, body
2. API runs outbound guard scan — if sensitive data found, email is blocked and owner notified
3. GatewayManager detects external recipient → routes to RelayGateway
4. RelayGateway sends via Gmail SMTP as owner+agentname@gmail.com
5. Reply-To set to agent's relay address so replies route back

Sending email (domain mode):

1. Agent calls POST /mail/send
2. Outbound guard scan runs
3. GatewayManager rewrites agent@localhost → agent@yourdomain.com
4. Email submitted to local Stalwart via SMTP (port 587)
5. Stalwart signs with DKIM, resolves MX, delivers directly (or via Gmail relay)

Receiving email (relay mode):

1. RelayGateway polls Gmail IMAP every 30 seconds for new messages
2. New email detected → parsed → spam scored
3. If not spam, delivered to agent's local Stalwart mailbox via SMTP
4. X-AgenticMail-Relay: inbound header added for identification
5. InboxWatcher (IMAP IDLE) fires SSE event to connected clients

Receiving email (domain mode):

1. External sender sends to agent@yourdomain.com
2. Cloudflare Email Routing catches all → routes to Email Worker
3. Worker reads raw RFC822 message, base64-encodes, POSTs to /api/agenticmail/mail/inbound
4. Inbound endpoint validates secret, parses email, delivers to agent's mailbox
5. InboxWatcher fires SSE event

---

Quick Start

Prerequisites

• Node.js 20 or later
• Docker (for the Stalwart mail server)

Install

npm install -g @agenticmail/cli

Setup

# 1. Start the mail server
docker compose up -d

# 2. Run the setup wizard (creates config, initializes database, creates first agent)
agenticmail setup

# 3. Start the API server + interactive shell
agenticmail start

The setup wizard will:

• Check Docker is running and Stalwart is healthy
• Generate a master API key
• Create the SQLite database with all required tables
• Create your first AI agent with its own email address and API key
• Optionally configure a gateway (relay or domain mode) for internet email

Send your first email (programmatic)

import { AgenticMailClient } from 'agenticmail';

const client = new AgenticMailClient({
  apiUrl: 'http://127.0.0.1:3100',
  apiKey: 'ak_your_agent_api_key',
});

// Send an email
await client.send({
  to: 'colleague@example.com',
  subject: 'Hello from my AI agent',
  text: 'This email was sent by an AI agent using AgenticMail.',
});

// Check inbox
const inbox = await client.listInbox(10);
for (const msg of inbox) {
  console.log(`${msg.from} — ${msg.subject}`);
}

// Read a specific email
const email = await client.readMessage(inbox[0].uid);
console.log(email.text);

Send your first email (CLI)

agenticmail> /send
To: someone@example.com
Subject: Test email
Body: Hello from the AgenticMail shell!

Email sent! Message ID: <abc123@localhost>

Send your first email (curl)

curl -X POST http://127.0.0.1:3100/api/agenticmail/mail/send \
  -H "Authorization: Bearer ak_your_agent_key" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "someone@example.com",
    "subject": "Hello",
    "text": "Sent via the AgenticMail API."
  }'

CLI Commands

AgenticMail includes a full CLI for managing your server. All commands are available via agenticmail <command> or npx @agenticmail/cli@latest <command>.

Core Commands

Command	Description
agenticmail	Start the server (runs setup first if not initialized). Opens the interactive shell after startup. This is the default command — just run agenticmail with no arguments.
agenticmail setup	Run the setup wizard. Walks you through system checks, account creation, service startup, email connection (Gmail/Outlook/custom domain), phone number setup, and OpenClaw integration. Safe to re-run — won't overwrite existing config.
agenticmail start	Start the server and open the interactive shell. Ensures Docker is running, Stalwart is up, and the API server is reachable. Automatically installs the auto-start service if not already set up.
agenticmail stop	Stop the server. Kills the background API server process. If auto-start is enabled, it will restart on next boot. Use agenticmail service uninstall to fully disable.
agenticmail status	Show what's running. Displays the status of Docker, Stalwart, the API server, email connection, and auto-start service.

Integration Commands

Command	Description
agenticmail openclaw	Set up AgenticMail for OpenClaw. Starts infrastructure, creates an agent, configures the OpenClaw plugin, enables agent auto-spawn via hooks, and restarts the OpenClaw gateway.

Service Management (Auto-Start)

AgenticMail installs a system service so it automatically starts when your computer boots. On macOS this is a LaunchAgent; on Linux it's a systemd user service.

Command	Description
agenticmail service	Show auto-start status. Displays whether the service is installed and running.
agenticmail service install	Install the auto-start service. AgenticMail will start automatically on boot. The startup script waits up to 10 minutes for Docker to be ready, then checks that Stalwart is running (starts it if needed), then launches the API server.
agenticmail service uninstall	Remove the auto-start service. AgenticMail will no longer start on boot.
agenticmail service reinstall	Reinstall the service. Use this after config changes or updates to refresh the service file.

What happens on reboot:

1. Your computer starts → Docker Desktop launches (its own auto-start)
2. Stalwart mail server starts (restart: unless-stopped in Docker)
3. AgenticMail startup script waits for Docker to be ready (up to 10 min)
4. Script verifies Stalwart is running (auto-starts it if Docker restarted without it)
5. API server starts and begins accepting requests

If the API server crashes, the system service automatically restarts it.

Maintenance Commands

Command	Description
agenticmail update	Update to the latest version. Checks npm for a new version, updates the CLI and OpenClaw plugin, and restarts the OpenClaw gateway if applicable.
agenticmail help	Show available commands.

Logs

Server logs are stored in ~/.agenticmail/logs/:

• server.log — API server stdout
• server.err.log — API server stderr
• startup.log — Boot sequence log (Docker wait times, Stalwart checks)

---

Gateway Modes

AgenticMail supports two modes for sending/receiving real internet email:

Relay Mode (Beginner-Friendly)

Use your existing Gmail or Outlook account as a relay. No domain purchase needed. Setup takes under 2 minutes.

How it works:

• Outbound: emails sent via your Gmail/Outlook SMTP as you+agentname@gmail.com
• Inbound: AgenticMail polls your Gmail/Outlook IMAP for new messages addressed to you+agentname@gmail.com and delivers them to the agent's local mailbox
• Gmail's + sub-addressing routes replies back to the right agent

Setup:

# In the interactive shell:
agenticmail> /relay

# Or via API:
curl -X POST http://127.0.0.1:3100/api/agenticmail/gateway/relay \
  -H "Authorization: Bearer mk_your_master_key" \
  -H "Content-Type: application/json" \
  -d '{
    "provider": "gmail",
    "email": "you@gmail.com",
    "password": "xxxx xxxx xxxx xxxx"
  }'

Requirements:

• Gmail: App password (not your regular password)
• Outlook: App password from Microsoft account security settings

Domain Mode (Advanced)

Full custom domain with Cloudflare. Agents send from agent@yourdomain.com with proper email authentication.

What gets configured automatically:

• Cloudflare DNS zone creation
• MX records pointing to Cloudflare Email Routing
• SPF record (v=spf1 include:_spf.mx.cloudflare.net ~all)
• DKIM key generation and TXT record
• DMARC record (v=DMARC1; p=quarantine)
• Cloudflare Tunnel (CNAME record, ingress rules)
• Cloudflare Email Worker deployment (catches all inbound email)
• Catch-all Email Routing rule → Worker → AgenticMail inbound endpoint
• Stalwart hostname, DKIM signing, domain principal
• @domain email aliases for all existing agents
• Optional: Gmail SMTP outbound relay, domain purchase

Setup:

curl -X POST http://127.0.0.1:3100/api/agenticmail/gateway/domain \
  -H "Authorization: Bearer mk_your_master_key" \
  -H "Content-Type: application/json" \
  -d '{
    "cloudflareToken": "your_cf_api_token",
    "cloudflareAccountId": "your_cf_account_id",
    "domain": "yourdomain.com",
    "gmailRelay": {
      "email": "you@gmail.com",
      "appPassword": "xxxx xxxx xxxx xxxx"
    }
  }'

Cloudflare API token permissions needed:

• Zone: DNS (Edit), Email Routing (Edit)
• Account: Cloudflare Tunnel (Edit), Workers Scripts (Edit), Registrar (Edit — only if purchasing domains)

MCP Integration

The MCP server exposes 62 tools to any MCP-compatible AI client via stdio transport.

Setup

Add to your MCP client configuration (e.g., .mcp.json or project settings):

{
  "mcpServers": {
    "agenticmail": {
      "command": "npx",
      "args": ["agenticmail-mcp"],
      "env": {
        "AGENTICMAIL_API_URL": "http://127.0.0.1:3100",
        "AGENTICMAIL_API_KEY": "ak_your_agent_key"
      }
    }
  }
}

Desktop Clients

For desktop AI applications, add the same configuration to your app's MCP config file (check your app's documentation for the file location).

What your AI can do

Once connected, your AI can:

• "Check my inbox" → list_inbox
• "Send an email to john@example.com about the project update" → send_email
• "Reply to that last email saying thanks" → reply_email
• "Search for emails from Sarah about the budget" → search_emails
• "Create a draft response to the client" → manage_drafts
• "What tasks are assigned to me?" → check_tasks
• "Ask the research agent to look up competitor pricing" → call_agent

See the MCP package README for the full tool list.

---

OpenClaw Integration

Already have OpenClaw? Two steps:

# Step 1 — Install AgenticMail globally and run the setup wizard
npm install -g @agenticmail/cli && agenticmail setup

# Step 2 — Connect AgenticMail to your OpenClaw instance
agenticmail openclaw

That's it. The global install gives you the agenticmail command. The openclaw command will start the mail server, create an agent, and merge the plugin config into your openclaw.json automatically. Your OpenClaw agent now has its own email address.

Manual Configuration

If you prefer to configure manually, add to ~/.openclaw/openclaw.json:

{
  "plugins": {
    "agenticmail": {
      "enabled": true,
      "config": {
        "apiUrl": "http://127.0.0.1:3100",
        "apiKey": "ak_your_agent_key",
        "masterKey": "mk_your_master_key"

The plugin survives OpenClaw updates — plugin configuration lives in user config (~/.openclaw/openclaw.json), not in the OpenClaw source directory.

Chat with Your AI Agent

Use /chat in the AgenticMail shell to talk directly to your OpenClaw agent in real-time:

╭───────────────────────────────────────────────╮
│ ❯ what's the weather in NYC?                  │
╰───────────────────────────────────────────────╯
                                          You 👤
                                  ╭──────────────╮

• WebSocket connection to OpenClaw gateway with Ed25519 device auth
• Bubble-style chat UI with markdown rendering
• Animated thinking indicator with elapsed timer
• Multi-line input (Enter sends, \ + Enter for new lines)

Smart Sub-Agent Spawning

The call_agent tool intelligently spawns sub-agents:

• Auto mode detection — light (simple tasks), standard (web research), full (multi-agent coordination)
• Dynamic timeouts — 60s / 180s / 300s based on complexity
• Dynamic tool discovery — probes OpenClaw config at runtime instead of static deny lists
• Async mode — call_agent(async=true) for long-running tasks. The caller polls /tasks/assigned for completion; the assigned agent emails the result back to the caller when it has email capability enabled. In a localhost-only / no-relay setup the result still lands in the caller's local mailbox, so check /mail/inbox if you don't see an SMTP delivery.
• Web search fallback — uses DuckDuckGo when Brave API isn't configured

See the OpenClaw package README for the full tool list.

Security

Outbound Guard

Every outgoing email is scanned before sending. The guard detects:

Category	Examples
API keys	sk-..., AKIA..., ghp_..., sk_live_...
Credentials	password: ..., secret: ..., token: ...
Private keys	-----BEGIN RSA PRIVATE KEY-----
PII	Social security numbers, credit card patterns
Internal data	Localhost URLs, internal IPs, config file contents

When sensitive data is detected:

1. Email is blocked and saved to the pending_outbound table
2. Agent receives a response explaining what was blocked and why, with instructions to inform their owner
3. Owner (master key holder) is notified via email with the full blocked email content, security warnings, recipient, subject, and pending ID
4. Owner approves or rejects via the master key API (POST /mail/pending/:id/approve or /reject) or by replying to the notification email
5. Agents cannot approve or reject their own blocked emails — the approve/reject endpoints require the master key
6. Agents can only list and view their pending emails to check approval status
7. MCP and OpenClaw tools enforce this by rejecting approve/reject actions with a message directing agents to inform their owner
8. System prompt guidelines (OpenClaw) instruct agents to never attempt self-approval or rewrite emails to bypass detection

Spam Filter

Inbound emails are scored against rule-based patterns:

Category	Score Range	Examples
Phishing	10-30	Fake login pages, urgency language, spoofed senders
Scam	15-25	Nigerian prince, lottery winner, inheritance schemes
Malware	20-30	Suspicious attachments, executable links
Commercial	5-15	Unsolicited marketing, unsubscribe-heavy emails
Social engineering	10-20	Impersonation, authority pressure

• Emails scoring >= 40 (configurable) are moved to Spam folder
• Emails scoring 20-39 get a warning flag
• Internal agent-to-agent emails skip spam filtering entirely
• Relay-rewritten emails (@localhost from, external replyTo) are always treated as external

Authentication

• Master key — full admin access, required for agent creation/deletion, gateway config, email approval
• Agent API keys — scoped per-agent, can only access own inbox and send from own address
• Inbound webhook secret — authenticates Cloudflare Email Worker requests to the inbound endpoint

Telemetry

AgenticMail collects anonymous usage statistics to help improve the product. We track:

• Tool call counts (which tools are popular)
• Package version and OS platform
• Anonymous install ID (random UUID, no personal data)

We never collect API keys, email content, addresses, or any personal information.

Opt out by setting the environment variable:

export AGENTICMAIL_TELEMETRY=0
# or
export DO_NOT_TRACK=1

Telemetry is also automatically disabled in CI environments.

Troubleshooting

OpenClaw plugin ID mismatch warning

plugin id mismatch (manifest uses "agenticmail", entry hints "openclaw")

This is harmless. OpenClaw infers the plugin ID from the npm package name (@agenticmail/openclaw) but the manifest declares "id": "agenticmail". The plugin loads and works correctly.

OpenClaw plugin path not found

If OpenClaw reports the plugin path not found, update plugins.load.paths in ~/.openclaw/openclaw.json to point to the correct location:

npm prefix -g
# Plugin is at: <prefix>/lib/node_modules/@agenticmail/openclaw

agenticmail: command not found

Use npx agenticmail for one-off usage, or install globally with npm install -g @agenticmail/cli.
