Windsurf

Open Cascade

Click the Cascade icon (the AI assistant panel).

Open MCP config

Click the hammer icon at the top of the Cascade panel, then click Configure.

Add the server

Add the OpenFinance server inside the mcpServers object:

{
  "mcpServers": {
    "openfinance-tech": {
      "serverUrl": "https://api.openfinance.tech/agent/mcp",
      "headers": {
        "x-api-key": "open_xxxxx"
      }
    }
  }
}

Drop the headers object if you only need public tools.

Refresh

Save the file. Click the Refresh button next to the MCP server list, or restart Windsurf.

Verify

OpenFinance should appear in the server list as connected.

Windsurf uses serverUrl instead of url. This is different from most other clients.
