Connect Hermes to Coinbase Agents MCP. List open orders in your portfolio, convert usd to btc at market price, and more using natural language, with authentication handled for you.
Coinbase Agents MCP is Coinbase's managed toolkit exposing accounts, portfolios, orders, fills, and market data. Use it to let authorized agents inspect holdings, execute trades, perform transfers, and handle payments.
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 Coinbase Agents 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.
Composio Connect is a consumer offering that lets anyone plug 1,500+ 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 Coinbase Agents
Ask your agent to connect to Coinbase Agents, or simply request any Coinbase Agents-related task. Hermes will prompt you to authenticate and authorize access.
4. Done. You're all set with a new Coinbase Agents 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 Coinbase Agents or request any Coinbase Agents-related task. It will prompt you to authenticate and authorize access.
5. Done!
The Coinbase Agents MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Coinbase account. It provides structured and secure access to your portfolios, balances, orders, trades, fees, market data, transfers, conversions, and x402 payments, so your agent can monitor holdings, research markets, manage orders, move funds, and make permitted payments on your behalf.
With Coinbase Agents 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:
