*Issue #, if available:

When executing the code below in Kiro and Visual Studio code on WIndows OS

Create an agent with MCP tools

with stdio_mcp_client:
# Get the tools from the MCP server
tools = stdio_mcp_client.list_tools_sync()

# Create an agent with these tools
agent = Agent(
    model="us.anthropic.claude-3-7-sonnet-20250219-v1:0",
    tools=tools)

response = agent("What is Amazon Bedrock pricing model. Be concise.")

Get the following error:
