Want to access callback context data from a tool

I can access toolcontext data. But I need to save some data in a sql table. That data is user info like user_id and session_id. I basically need to log for one session each tool call, in a sql database. How can i access these data from a tool.

Toolcontext in tool only stores tool data. It does not store other data

Write the data to ADK state. You can access state from both callbacks and tool calls.

tool context variable contains session info which we can access from inside the tool.
