Is dynamic tool loading the same as deleting tools from the agent?

If we turn on dynamic tool loading, are we removing tools the agent is allowed to call?

No. The tools stay available. The agent discovers them as short summaries and fetches the full schema only for the action it is about to run. You still decide which MCP tools that agent may see. Projection then drops response fields the task does not need. Deleting a tool removes permission. Loading only keeps the context small.
