• src/csv_editor/tools/io_operations.py:363-406 (handler)

  Core implementation of the get_session_info tool. Retrieves session from manager, extracts info, and returns formatted OperationResult.

  async def get_session_info(
      session_id: str,
      ctx: Context = None
  ) -> Dict[str, Any]:
      """Get information about a specific session.
      
      Args:
          session_id: Session ID
          ctx: FastMCP context
      
      Returns:
          Session information
      """
      try:
          session_manager = get_session_manager()
          session = session_manager.get_session(session_id)
          
          if not session:
              return OperationResult(
                  success=False,
                  message="Session not found",
                  error="Invalid session ID"
              ).model_dump()
          
          if ctx:
              await ctx.info(f"Retrieved info for session {session_id}")
          
          info = session.get_info()
          return OperationResult(
              success=True,
              message="Session info retrieved",
              session_id=session_id,

          ).model_dump()
          
      except Exception as e:

              await ctx.error(f"Failed to get session info: {str(e)}")
          return OperationResult(

• src/csv_editor/server.py:160-167 (registration)

  Registers the get_session_info tool with FastMCP using @mcp.tool decorator. Acts as a thin wrapper delegating to the core handler.

  @mcp.tool
  async def get_session_info(
      session_id: str,
      ctx: Context = None
  ) -> Dict[str, Any]:
      """Get information about a specific session."""
      return await _get_session_info(session_id, ctx)

• src/csv_editor/server.py:98-106 (registration)

  Imports the core get_session_info handler from io_operations module, aliased as _get_session_info for use in the server registration.

  from .tools.io_operations import (
      load_csv as _load_csv,
      load_csv_from_url as _load_csv_from_url,
      load_csv_from_content as _load_csv_from_content,
      export_csv as _export_csv,
      get_session_info as _get_session_info,
      list_sessions as _list_sessions,
      close_session as _close_session
  )
