OpenClaw is the fastest growing agent harness out there, which can work 24/7 to automate almost any kind of tasks. However, its capabilities are limited to the tools it has access to. Composio allows your OpenClaw to access Smtp2go with authentication management handled for you. You can execute actions on Smtp2go via your favorite OpenClaw interface (Telegram, WhatsApp, TUI, etc), whichever you prefer.

Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Handling Large tool responses out of LLM context to minimize context rot.
- Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need.
How to install Smtp2go with OpenClaw
Using Composio API Key and Setup Prompt
- Go to dashboard.composio.dev
- Copy the setup prompt
- Run it in your OpenClaw chat interface.
- Authenticate Smtp2go from the dashboard
- Go back to your OpenClaw interface and start asking questions.
Using OpenClaw/Composio Plugin
1. Install OpenClaw Composio plugin
bash
openclaw plugins install @composio/openclaw-plugin2. Copy the API Key from dashboard.composio.dev
3. Setup OpenClaw Config
bash
openclaw config set plugins.entries.composio.config.consumerKey "ck_your_key_here"4. Restart OpenClaw
bash
openclaw gateway restart5. Go to your chat interface and start asking questions.
6. When prompted, authenticate the app and you're all set.
How It Works
The plugin connects to Composio's MCP server at https://connect.composio.dev/mcp and registers all available tools directly into the OpenClaw agent. Tools are called by name — no extra search or execute steps needed.
If a tool returns an auth error, the agent will prompt you to connect that toolkit at dashboard.composio.dev.
Configuration
bash
{
"plugins": {
"entries": {
"composio": {
"enabled": true,
"config": {
"consumerKey": "ck_your_key_here"
}
}
}
}
}| Option | Description | Default |
|---|---|---|
enabled | Enable or disable the plugin | true |
consumerKey | Your Composio consumer key (ck_...) | — |
mcpUrl | MCP server URL (advanced) | https://connect.composio.dev/mcp |
What is the Smtp2go MCP server, and what's possible with it?
The Smtp2go MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Smtp2go account. It provides structured and secure access to your email sending and management infrastructure, so your agent can perform actions like searching email activity, managing allowed senders, updating sender domains, and controlling IP allow lists on your behalf.
- Comprehensive email activity search: Ask your agent to filter and retrieve email events such as sends, opens, clicks, and bounces by recipient, date, or message ID.
- Allowed sender management: Have your agent add, update, remove, or view allowed sender email addresses to control who can send emails from your account.
- Sender domain configuration: Let the agent register new sender domains for SPF/DKIM verification and manage domain-related settings seamlessly.
- IP allow list control: Direct your agent to add or remove IP addresses or CIDR ranges in your account’s IP allow list, enhancing security for sending sources.
- Email delivery monitoring: Enable your agent to search and analyze sent emails, helping you monitor delivery, troubleshoot issues, and ensure reliable communication.
Conclusion
You've successfully integrated Smtp2go with OpenClaw using Composio plugin. Now interact with Smtp2go directly from your terminal, Web UI, or any messenger app using natural language commands.
Key benefits of this setup:
- Seamless integration across TUI, Web UIs, and Messenger apps like Telegram, WhatsApp, Slack, etc.
- Natural language commands for Smtp2go operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1000+ apps for cross-app workflows
- Programmatic tool calling for complex tool chaining
Next steps:
- Try asking OpenClaw to perform various Smtp2go operations
- Explore cross-app workflows by connecting more toolkits like Calendar, Slack, Notion, etc.

FAQ
Frequently asked questions
With a standalone Smtp2go MCP server, the agents and LLMs can only access a fixed set of Smtp2go tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Smtp2go and many other apps based on the task at hand, all through a single MCP endpoint.
Yes, you can. OpenClaw 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 Smtp2go tools.
Yes, absolutely. You can configure which Smtp2go 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.
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 Smtp2go data and credentials are handled as safely as possible.
