Hermes Agent (from Nous Research) speaks MCP natively. You can add OpenFinance either through the CLI or by editing the config file directly.

​
Option A, CLI

hermes mcp add openfinance-tech --url https://api.openfinance.tech/agent/mcp
Verify it is configured: 
hermes mcp list
Test the connection: 
hermes mcp test openfinance-tech

​
Option B, edit config.yaml

Open ~/.hermes/config.yaml and add the OpenFinance server under mcp_servers: 
mcp_servers:
  openfinance-tech:
    url: "https://api.openfinance.tech/agent/mcp"
Hermes uses YAML, not JSON. Indentation matters, use two spaces and avoid tabs.

​
Tool filtering (optional)

Hermes recommends a least-privilege approach. You can restrict which OpenFinance tools the agent sees with an include whitelist: 
mcp_servers:
  openfinance-tech:
    url: "https://api.openfinance.tech/agent/mcp"
    headers:
      x-api-key: "open_xxxxx"
    tools:
      include: [getFundingRates, getPositions, previewTrade]
This is a good pattern when you only want the agent to read data and preview trades, but never build or submit transactions.

​
Reload

Run /reload-mcp inside Hermes, or restart the agent. OpenFinance tools will appear alongside Hermes’s built-in tools.
