Connect OpenCode to Agent mail MCP. Show me unread emails from today, send a status update to your team, and more using natural language, with authentication handled for you.
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.
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:
Composio provides a single MCP server or CLI tool that exposes a set of meta-tools, allowing you to:
Install the Composio CLI, authenticate, and initialize your project:
# Install the Composio CLI
curl -fsSL https://composio.dev/install | bash
# Authenticate with Composio
composio loginDuring login, you will be redirected to the sign-in page. Finish the flow and you are all set.
Once the CLI is installed, it is essentially done. Give OpenCode access to your apps with these steps:
You can also connect Agent mail to OpenCode by adding Composio as an MCP server through the OpenCode CLI.
opencode mcp addThis launches an interactive prompt.
| Field | Value |
|---|---|
| Name | composio |
| Type | remote |
| URL | https://connect.composio.dev/mcp |
| Require OAuth | Yes |
| Have client ID | No |
Alternatively, you can skip the interactive prompt and paste the configuration directly into your OpenCode config file.
Open your global OpenCode config:
open ~/.config/opencode/opencode.jsonAdd this under the mcp key and save the file.
{
"mcp": {
"composio": {
"type": "remote",
"url": "https://connect.composio.dev/mcp",
"enabled": true
}
}
}Authenticate the Composio MCP server you just added:
opencode mcp auth composioThis opens a browser session. Authorize Composio and you are done.
opencode mcp listNow, in the chat, ask the agent to connect to Agent mail or give it any Agent mail-related task.
For example, ask it to:
It will prompt you to authenticate and authorize access to Agent mail.
That is it. Composio tools are now available in OpenCode, and your Agent mail account is ready to use.
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.
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.
Every Agent mail action and event your agent gets out of the box.
