## Introduction

### How to integrate Agent mail MCP with OpenCode
This guide explains how to connect Agent mail MCP to OpenCode using Composio Connect, which simplifies OAuth, API changes, and reliability concerns.
There are two ways to set this up:
- Via [Composio Connect MCP](https://dashboard.composio.dev/)
- Via the [Composio CLI](https://dashboard.composio.dev/)

## TL;DR

### Why use Composio?
Composio provides a single MCP server or CLI tool that exposes a set of meta-tools, allowing you to:
- Connect to 1,000+ apps with on-demand tool loading, so you do not fill your LLM context window with unnecessary tool definitions.
- Use programmatic tool calling through a remote Bash tool, letting LLMs write their own code to handle complex tool chaining. This reduces back-and-forth for frequent tool calls.
- Handle large tool responses outside the LLM context to keep conversations lean.

## Connect Agent mail to OpenCode

### Connect Agent mail with OpenCode
### Option 1: Using Composio CLI
### 1. Install Composio CLI
Install the Composio CLI, authenticate, and initialize your project:

```bash
# Install the Composio CLI
curl -fsSL https://composio.dev/install | bash

# Authenticate with Composio
composio login
```

## 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_GET_MESSAGE` | Get Message | Get a specific message from an agentmail inbox |
| `AGENT_MAIL_LIST_MESSAGES` | List Messages | List messages from an agentmail inbox |
| `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

Once connected, OpenCode can access the Agent mail MCP server via Composio to run the app actions you authorize, directly from your coding workflow.

## Complete Code

None listed.

## Conclusion

### Way Forward
Now that Agent mail is connected, extend your setup by connecting the other apps you already use every day, so your agent can run true cross-app workflows end to end.
- Connect Calendar to turn threads into scheduled meetings automatically.
- Connect Slack or Teams to post summaries, approvals, and alerts where your team works.
- Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs.
- Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps.
Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single MCP endpoint, your agent can coordinate multiple tools safely and reliably in one conversation.

## 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 OpenCode?

Yes, you can. OpenCode 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.
