# Errors

> Common CLI and MCP failures.

## Not authenticated

```txt theme={null}
not authenticated. Run: aeo auth login
```

Fix:

```bash theme={null}
aeo auth login
```

For automation, set:

```bash theme={null}
export AEOLO_API_KEY=atok_...
```

## Domain required

Fix by passing a domain or selecting one:

```bash theme={null}
aeo domain list
aeo domain switch <domain_id>
```

or:

```bash theme={null}
export AEOLO_DOMAIN_ID=<domain_id>
```

## MCP bad accept header

If the MCP endpoint rejects the request, include:

```http theme={null}
Accept: application/json, text/event-stream
```

## Local file through MCP

MCP clients cannot pass local filesystem paths to the server. Use inline content or a URL.
