qwen_agent/tools/mcp_manager.py", line 142
logger.info(f'Initializing MCP tools from mcp servers: {list(config['mcpServers'].keys())}')

this causes error

Is there a problem with the configuration?

装了新版本的qwen-agent后就出现这个问题了！ 今天才发现的。 之前一直没有这个问题！

Simply fix the incorrect f-string:

change

logger.info(f'Initializing MCP tools from mcp servers: {list(config['mcpServers'].keys())}')

to

logger.info(f"Initializing MCP tools from mcp servers: {list(config['mcpServers'].keys())}")

I created a PR to fix this bug:

#770

官方不修复吗？
