Feature Request: Add tool filtering/selection capability for MCP Servers

Problem Description:
Currently, the Agent SDK automatically fetches all available tools from MCP servers without the ability to select only specific tools. This creates inconveniences in the following scenarios:

1. MCP servers provide numerous tools, but the Agent only needs to use a subset of them. In many cases, only a subset of tools is needed, and unwanted tools occupy LLM context and affect the accuracy of Agent tool selection.
2. Different Agents need to use different tool subsets from the same MCP server
3. Security concerns require limiting the scope of tools an Agent can access
4. Avoiding tool name conflicts (when multiple servers have tools with the same name)
