Bug: VeIdentityMcpToolset has redundant tool filtering/prefix logic and a bug in prefix implementation

从 veadk/integrations/ve_identity/mcp_toolset.py 的第 95-99 行和第 152-170 行开始，然后将实现与 base_tool.py 中的 BaseToolset 和 BaseTool 进行比较。验证前缀行为和继承工具过滤，移除冗余的子类逻辑，并运行相关的现有测试套件，以确认这两种行为仍然正确。

Description

The VeIdentityMcpToolset class redundantly implements functionality already provided by the parent class BaseToolset. More critically, the tool name prefix implementation contains a bug: the code modifies the _name attribute, but the actual effective attribute is name (class attribute), causing the prefix feature to completely fail.

Code Locations

• File: veadk/integrations/ve_identity/mcp_toolset.py
• Relevant lines: L95-L99, L152-L153, L156-L170

Specific Issues

1. 🔴 Critical Bug: Incorrect tool name prefix implementation (L152-L153)

# Current implementation (Bug)
if self._tool_name_prefix:
    mcp_tool._name = f"{self._tool_name_prefix}{mcp_tool.name}"

Problem:

• In BaseTool, name is a class attribute (base_tool.py#L45), and the instance attribute is also self.name
• The code modifies _name (single underscore), but the actual tool uses the name attribute
• This causes the prefix feature to completely fail

Verification:

# In BaseTool
class BaseTool(ABC):
    name: str  # Class attribute
    """The name of the tool."""
    
    def __init__(self, *, name, ...):
        self.name = name  # Instance attribute is name, not _name

2. Redundant storage of tool filter and prefix attributes (L95-L99)

# Current implementation (redundant)
self._tool_filter = tool_filter
self._tool_name_prefix = tool_name_prefix

Problem: These two attributes are already stored in the parent class BaseToolset.__init__() as self.tool_filter and self.tool_name_prefix. This uses underscore prefix to redundantly store them.

3. Completely duplicate _is_tool_selected method (L156-L170)

Problem: This method is identical to the parent class BaseToolset._is_tool_selected() implementation, which is completely redundant code.

Impact

1. 🔴 Feature failure: Tool name prefix feature completely doesn't work
2. Code redundancy: Same logic implemented in multiple places, increasing maintenance burden
3. Risk of inconsistent behavior: If parent class logic is updated, the child's duplicate implementation may miss synchronization
