## Recipe

1. Add the Custom MCP tool to your agent flow and paste the configuration below.
2. Under Variables create aichargedKey with your API key <API_KEY>.

Node configuration with a Flowise variable:

```json
{
  "url": "https://aicharged.io/api/v1/mcp",
  "headers": {
    "Authorization": "Bearer {{$vars.aichargedKey}}"
  }
}
```

Create a variable named aichargedKey under Variables in Flowise and put your API key there.

Config with the key inline:

```json
{
  "url": "https://aicharged.io/api/v1/mcp",
  "headers": {
    "Authorization": "Bearer <API_KEY>"
  }
}
```
