In this paper, we introduce platform specific modeling and code generation tools for the model driven development of multi-agent systems (MAS). These tools enable agent developers to model their MASs for the SEAGENT and the JADEX agent platforms based on the semantics and design principles of these platforms. The toolkit also provides automatic code generation for agent developers in order to implement their MASs on the target platforms. Generated codes may vary on type (e.g. Java class files, XML documents or ontologies) according to each platform's requirements.
