hey @pietrozullo / @NandhuKishore24 , can you please review the changes for this request.

Hey @THARUN-S-R actually the chat id has no function on the local agent but only on the remote execution. I am not sure what are you trying to do here, could you explain ?

Hi @pietrozullo , I am using the Chat Id to pass a unique hash value to identify each agent run or Chat. This will be then added to the conversation history. I need to find each Chat to add a feedback to the response. This way i can identify the chat and improve prompting based on user feedback. For this langchain BaseMessage has optional id field which we can use to identify each chat.

Hey @THARUN-S-R I am still not sure I follow, have you see what the chat_id is used for inside the agent ? The chatID is a reference to the cloud hosted agent in the library context, it will not have anything to do with chat persistence locally, even after your changes. Also I see you are passing it in the langchain messages, which is fine, but that id is supposed to be unique for every message not a common one for a chat. If you want to persiste the messages in a chat you can create a Chat class where you persist them and you can have the Chat take an ID.

Maybe I am not seeing something here but this PR does not seem to solve the problem you want to address, imo

Hi @pietrozullo , yes the chat id initially is used only for remote agent, but in my use case I want to mark each chat with a unique id to reference it back later. Hence, this field was already there which i can use to pass the unique id into the Messages. This way i dont need a new parameter to achieve this and can be assigned in Chat_id. About the uniqueness of the id, before triggering the run(query) func, I will assign the agent a new chat id as :
agent.chat_id = chat_id
this assignment is not within the MCP-USE architecture and is at the users discretion. this way it doesnt affect the architecture if not passed but gives the user options to assign an id to the messages.:

This way I can easily identify the chats I want to refer back to. The user can have a feedback to the chat generated which we can use to adjust our prompt accordingly. This is just one of the use case of the Chat ID.
