Allow users to add more mcp servers during a chat app lifecycle

[minhrongcon2000]

Description

In a user's chat session, what if he/she wants to add more mcp servers? Do we need to restart the entire web service just to add more server? That's why I want to propose a feature to track mcp tool uses during a chat app lifecycle!

In case of stdio transport, yes. But you can create an SSE based one.

Regarding SSE, I see from the codebase that we cannot add new server once Agent object is instantiated! If I follow this example, it would become more inflexible if I want to dynamically add more server. I could try inheriting the Agent class and modify its behaviour but since it is marked as final class. I don't think this is a desired way...

I havent tried this yet, but I think you may just be able to add to agent._mcp_servers. Things don't seem to be cached and are evaluated at run time (.iter(), etc.) - I could be mistaken though
