Why have you added the data store as MCP in the Agent? I would advice you to add it as a tool, either by creating a scenario that can access the records in the data store or as a module.
The best way is by utilizing tools. Tool are modules and scenarios your agent uses to make decisions and complete tasks across all workflows.
When an agent processes requests, it uses tool names and descriptions to choose the right tool for the task. When using scenarios as tools, it processes scenario inputs and outputs names and descriptions to choose the right data.
