Cursor with my mcp, many errors, and I don't know how to do

[yan_Yan]

Describe the Bug

I just want to learn about Agent, it is just a demo, but i can not run it succeed, this is my code:

server.py
import sys
sys.path.append(‘E:\TaoPaoJiHua\MCP-3’)
from mcp.server.fastmcp import FastMCP
from finance_crew import run_Naruto_analysis

mcp = FastMCP(“Naruto-analysis”)

@mcp.tool()
def analyze_Naruto(query: str) → str:
“”"
对火影中人物的分析，输入人物名字，输出人物的分析结果。包括：人物的家庭结构，人物的忍术，人物的背景故事，人物的战斗风格，人物的结局。

Args:
    query (str): 输入的火影人物名称.

Returns:
    str: 对人物的分析结果.
"""
try:
    result = run_Naruto_analysis(query)
    # result = "ok"
    return result
except Exception as e:
    return f"Error: {e}"

if name == ‘main’:
mcp.run(transport=‘stdio’)

query_parser_agent = Agent(

goal=“请根据用户提供的火影中的人物名称，对该人物进行详细的介绍: {query}”,
backstory=“你是一个资深的火影系列研究专家”,
llm=llm,
verbose=True,
memory=True,
)

query_parsing_task = Task(
description=“对用户提供的火影人物进行全面的分析”,
expected_output=“markdown格式的输出结果，从人物的家庭结构，人物的忍术，人物的背景故事，人物的战斗风格，人物的结局这几方面进行格式化输出”,
agent=query_parser_agent,
)

crew = Crew(
agents=[query_parser_agent], #code_writer_agent, code_execution_agent],
tasks=[query_parsing_task], #code_writer_task, code_execution_task],
process=Process.sequential
)

def run_Naruto_analysis(query):
result = crew.kickoff(inputs={“query”: query})
return result.raw

if name == ‘main’:
result = crew.kickoff(inputs={“query”: “日向宁次”})
print(result.raw)
