Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows. This guide explains the easiest and most robust way to connect your Postmark account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.
Postmark is an email delivery service for sending transactional emails with reliable deliverability. It delivers detailed analytics and fast, secure email delivery for developers.

Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can:
1. Install the Composio CLI
Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.
curl -fsSL https://composio.dev/install | bash
2. Authenticate
Once the CLI is installed, ask Hermes to authenticate with Composio.
3. Connect to Postmark
Ask your agent to connect to Postmark, or simply request any Postmark-related task. Hermes will prompt you to authenticate and authorize access.
4. Done. You're all set with a new Postmark connection.
1. Get your MCP URL and API Key
Go to dashboard.composio.dev and copy your Connect MCP URL and API key.
2. Open the Hermes config file
nano ~/.hermes/config.yaml3. Add the Composio Connect MCP server
mcp_servers:
composio:
url: "https://connect.composio.dev/mcp"
headers:
x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
connect_timeout: 60
timeout: 180Save with Ctrl + O, Enter, then exit with Ctrl + X.
4. Restart your Hermes agent
Once restarted, ask your agent to connect to Postmark or request any Postmark-related task. It will prompt you to authenticate and authorize access.
5. Done!
The Postmark MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Postmark account. It provides structured and secure access to transactional email sending and analytics, so your agent can perform actions like delivering transactional emails, monitoring delivery status, managing templates, and analyzing engagement metrics on your behalf.
With Postmark connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.
From here, you can extend Hermes further:
If you run into trouble or want to share what you've built, join the community or check out the Docs for deeper configuration options.
Every Postmark 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.
