## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Agent mail MCP or direct API to send emails, fetch inbox messages, organize threads, and automate email workflows through natural language.

## Summary

Agent mail provides AI agents with dedicated email inboxes for sending, receiving, and managing emails. It empowers agents to communicate autonomously with people, services, and other agents—no human intervention needed.

## Categories

- collaboration & communication

## Toolkit Details

- Tools: 5
- Triggers: 1

## Images

- Logo: https://logos.composio.dev/api/agent_mail

## Authentication

- **Api Key**
  - Type: `api_key`
  - Description: Api Key authentication for Agent Mail.
  - Setup:
    - Configure Api Key credentials for Agent Mail.
    - Use the credentials when creating an auth config in Composio.

## Suggested Prompts

- Show me unread emails from today
- Send a status update to my team
- Find emails with invoice attachments
- Forward the latest client message to support

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `AGENT_MAIL_CREATE_INBOX` | Create Inbox | Create a new AgentMail inbox via API. Returns the inbox_id and email address for sending/receiving messages. Use when provisioning new inboxes for agents or workflows. |
| `AGENT_MAIL_GET_MESSAGE` | Get Message | Retrieve the complete details of a specific email message from an AgentMail inbox. This action returns the full message content including sender, recipients, subject, body (both text and HTML), attachments, labels, and metadata. Use this to read individual messages after discovering them via LIST_MESSAGES or webhooks. |
| `AGENT_MAIL_LIST_INBOXES` | List Inboxes | List all inboxes available to the authenticated AgentMail account. Use this to discover valid inbox_id values for message operations. |
| `AGENT_MAIL_LIST_MESSAGES` | List Messages | List messages from an AgentMail inbox. Returns a `messages` array; each message uses `message_id` and `timestamp` fields (not `id`, `date`, or `items`). |
| `AGENT_MAIL_SEND_EMAIL` | Send Email | Send an email using AgentMail API |

## Supported Triggers

| Trigger slug | Name | Description |
|---|---|---|
| `AGENT_MAIL_NEW_EMAIL_TRIGGER` | New Email Received | Trigger for new emails in an AgentMail inbox |

## Installation and MCP Setup

### Path 1: SDK Installation

#### Path 1, Step 1: Install Composio

Install the Composio SDK
```python
pip install composio_openai
```

```typescript
npm install @composio/openai
```

#### Path 1, Step 2: Initialize Composio and Create Tool Router Session

Import and initialize Composio client, then create a Tool Router session
```python
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
openai = OpenAI()
session = composio.create(user_id='your-user-id')
```

```typescript
import OpenAI from 'openai';
import { Composio } from '@composio/core';
import { OpenAIResponsesProvider } from '@composio/openai';

const composio = new Composio({
  provider: new OpenAIResponsesProvider(),
});
const openai = new OpenAI({});
const session = await composio.create('your-user-id');
```

#### Path 1, Step 3: Execute Agent mail Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Agent mail actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'Summarize unread emails from today'
  }]
)
result = composio.provider.handle_tool_calls(
  response=response,
  user_id='your-user-id'
)
print(result)
```

```typescript
const tools = session.tools;
const response = await openai.responses.create({
  model: 'gpt-4.1',
  tools: tools,
  input: [{
    role: 'user',
    content: 'Summarize unread emails from today'
  }],
});
const result = await composio.provider.handleToolCalls(
  'your-user-id',
  response.output
);
console.log(result);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK and Claude Agent SDK
```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcp
```

#### Path 2, Step 2: Create Tool Router Session

Initialize the Composio client and create a Tool Router session
```python
from composio import Composio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions

composio = Composio(api_key='your-composio-api-key')
session = composio.create(user_id='your-user-id')
url = session.mcp.url
```

```typescript
import { Composio } from '@composio/core';

const composio = new Composio({ apiKey: 'your-api-key' });

console.log("Creating Tool Router session...");
const { mcp } = await composio.create('your-user-id');
console.log(`Tool Router session created: ${mcp.url}`);
```

#### Path 2, Step 3: Connect to AI Agent

Use the MCP server with your AI agent
```python
import asyncio

options = ClaudeAgentOptions(
    permission_mode='bypassPermissions',
    mcp_servers={
        'tool_router': {
            'type': 'http',
            'url': url,
            'headers': {
                'x-api-key': 'your-composio-api-key'
            }
        }
    },
    system_prompt='You are a helpful assistant with access to Agent mail tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('List all unread messages in my Agent mail inbox')
        async for message in client.receive_response():
            if hasattr(message, 'content'):
                for block in message.content:
                    if hasattr(block, 'text'):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText, stepCountIs } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: mcp.url,
    headers: { 'x-api-key': 'your-composio-api-key' }
  }
});

const tools = await client.tools();

const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{ role: 'user', content: 'List all unread messages in my Agent mail inbox' }],
  stopWhen: stepCountIs( 5 )
});

console.log(`Agent: ${text}`);
```
