Integration of agent with 'traditional' backend systems

[rickywck]

If I want to integrate my agents to various backend systems which are not Python based, do not speak MCP nor A2A language, what is the recommended approach? Technically I need to create wrappers for these systems, but which is the better approach to implement these wrappers? e.g. develop wrappers in Python functions and invoke APIs of backend systems, create MCP server for existing systems, etc. Besides skills and tech stack (for example if I want to use Javascript for these wrappers then the logical choice seems to be build MCP servers), what are the other considerations?

I would say if you have an OpenAPI spec for each backend with Authentication, you could use ADK's OpenAPI tool. Just make sure you document your endpoints well.
