Hi @richard-gyiko ,

Thanks for this PR ..
Can you provide some instructions on how to test with this a local MCP server? The example you have hints at some url with an mcp server and translate tool capabilities. Is there a clear way to set it up and test locally?
I tried setting up a sample mcp server (and could explore it locally using the mcp inspector), but it was unclear how to use it with the tool interface provided here.

Hi @victordibia ,

I've updated the sample on the community repo which now includes the fetch and the file system MCP server tools:
https://github.com/richard-gyiko/autogen-ext-mcp/tree/main/samples

MCP Server installations and usage is covered in the README and the sample code.

Hope it gives sufficient amount of information. If not, please let me know.

Could you also create a sample under python/samples to showcase a scenario, in a separate PR? E.g., chatting with a Git repo agent using the Git server.
