I was trying to use firecrawl-mcp-server with Smolagents. The import of the tool collection was not possible because of a type error.

k,v allowExternalLinks {'type': 'boolean', 'description': 'Allow crawling links to external domains'}
k,v webhook {'oneOf': [{'type': 'string', 'description': 'Webhook URL to notify when crawl is complete'}, {'type': 'object', 'properties': {'url': {'type': 'string', 'description': 'Webhook URL'}, 'headers': {'type': 'object', 'description': 'Custom headers for webhook requests'}}, 'required': ['url']}]}

I added some checks and handling of oneOf in the code for smolagents and issued a PR ( #14 )
