Describe the feature

Is it possible to select only some tools from MCP servers and assign to an agent?
For example, I have a read_agent, and a write_agent. The read_agent only have access to all read-only tools from the MCP server, while the write_agent have access to write tools (or just one specific write tool).

I think the current implementation assigns all available tools to the agent.

agent = Agent(
        name="Assistant",
        instructions="Use the tools to answer the questions.",
        mcp_servers=[mcp_server],
        model_settings=ModelSettings(tool_choice="required"),
    )

Nothing built in, but you can create your own MCPServer istance

class MyMCPServer(MCPServer):
  def __init(self, actual_server: MCPServer):
     self.actual_server = actual_server

  async def list_tools(self):
      tools = await self.actual_server.list_tools()
      return [tool for tool in tools if tool.name.startswith("write")
  
 ...

@rm-openai That would be great if it could be in a helper function. :)
