How to integrate Mailtrap MCP with OpenCode This guide explains how to connect Mailtrap 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 Via the Composio CLI
Mailtrap is an email delivery platform for safe email testing and transactional email sending. It helps you catch bugs and verify email flows without spamming real inboxes.
This guide explains how to connect Mailtrap 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 Mailtrap 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 Mailtrap or give it any Mailtrap-related task.
For example, ask it to:
It will prompt you to authenticate and authorize access to Mailtrap.
That is it. Composio tools are now available in OpenCode, and your Mailtrap account is ready to use.
Now that Mailtrap 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 Mailtrap action and event your agent gets out of the box.

Karan skipped his own birthday party to fix our critical issue. It was 10pm and he diverted his Waymo to help us instead. This really sets the bar — it shows the commitment you need when users rely on your software.
A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.
We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.
As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.
Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.
With hands-on help from their founder, we integrated Gmail and Google Drive in just 30 minutes. This level of personal support and commitment is exactly what startups should strive for.
