## Introduction

Pi is a minimal, self-extensible coding agent that lives in your terminal — one agent loop over Claude, GPT-5, Gemini, Grok, DeepSeek, and 20+ other providers, with maximum extension surface and minimum product opinion. Its core ships four tools (read, write, edit, bash) and self-extends at runtime through skills, extensions, and packages.
This guide explains the easiest and most robust way to connect your Agent mail account to Pi. You can do this through either Composio Connect CLI or Composio Connect MCP. Because Pi already runs shell commands as first-class tools and ships no built-in MCP, the CLI is the recommended path — it's faster to set up, needs no server config, and chains multi-step tasks more reliably. The MCP path is also fully supported through Pi's official pi-mcp-adapter extension.

## TL;DR

### What is Composio Connect?
Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Pi. It can:
- Search and load tools from relevant toolkits on-demand, reducing context usage.
- Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
- Manage app authentication end-to-end with zero manual overhead.

## Connect Agent mail to Pi

### Prerequisites: Install Pi
Pi needs Node.js 18+ (Node 22 recommended). Install the agent globally with npm:

```bash
npm install -g --ignore-scripts @earendil-works/pi-coding-agent
```

## What is the Agent mail MCP server, and what's possible with it?

The Agent mail MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Agent mail account. It provides structured and secure access to your agent's dedicated inbox, so your agent can send emails, receive incoming messages, fetch specific conversations, and automate email-based workflows on your behalf.
- Automated email sending: Instruct your agent to compose and send emails to any recipient, perfect for status updates, notifications, or outreach.
- Message listing and inbox scanning: Let your agent quickly list all recent messages in the inbox to summarize, monitor, or trigger follow-up actions.
- Targeted message retrieval: Have your agent fetch a specific message by ID, making it easy to pull full email content for context-aware decisions or replies.
- Streamlined agent-to-agent communication: Enable your AI to directly interact with other agents or services via email, automating routine communication flows.

## 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 |

## Creating MCP Server - Stand-alone vs Composio SDK

The Agent mail MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Pi, Claude, Cursor, etc. directly to your Agent mail account. It provides structured and secure access so your agent can act on your behalf using natural language commands.

## Conclusion

### Way Forward
With Agent mail connected, Pi can now act on your behalf whenever you ask it to.
From here, you can extend Pi further:
- Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Pi can do for you.
- Build workflows across tools: Once multiple apps are connected, Pi can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
- Lean into Pi's extension surface: Wrap common Agent mail flows as Pi skills or prompt templates so recurring tasks become one-line commands, and use directTools in the MCP adapter to promote your most-used Agent mail tools into Pi's tool list directly.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Agent mail MCP?

With a standalone Agent mail MCP server, the agents and LLMs can only access a fixed set of Agent mail tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Agent mail and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Pi?

Yes, you can. Pi fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Agent mail tools.

### Can I manage the permissions and scopes for Agent mail while using Tool Router?

Yes, absolutely. You can configure which Agent mail scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Agent mail data and credentials are handled as safely as possible.
