JsonSchema missing items when parsing properties

I encountered an exception when trying to call the FileSystem MCP Server because the items property was not parsed, which resulted in the failure to pass the OpenAI format check.

This is the definition of a tool returned by the mcp server:

{
	"name": "read_multiple_files",
	"description": "Read the contents of multiple files simultaneously. This is more efficient than reading files one by one when you need to analyze or compare multiple files. Each file\u0027s content is returned with its path as a reference. Failed reads for individual files won\u0027t stop the entire operation. Only works within allowed directories.",
	"inputSchema": {
		"type": "object",
		"properties": {
			"paths": {
				"type": "array",
				"items": {
					"type": "string"
				}
			}
		},
		"required": ["paths"],
		"additionalProperties": false,
		"$schema": "http://json-schema.org/draft-07/schema#"
	}
}

Currently missing parsing for [properties.paths.items]
