from qwen_agent.tools import MCPManager
class MCPManager:
def initConfig(self, config: Dict) -> List[BaseTool]
config = {
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "/allowed/path"]
},
"database": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-sqlite", "db.sqlite"]

Usage Example
Basic MCP Integration
from qwen_agent.agents import FnCallAgent
# MCP server configuration
mcp_config = {
"mcpServers": {
"memory": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-memory"]
}
}
}
# Create agent with MCP tools
agent = FnCallAgent(
function_list=[mcp_config],
llm={'model': 'qwen-max'}
)
messages = [{
'role': 'user',
'content': 'Remember that my favorite color is blue'
}]
for response in agent.run(messages):
print(response[-1].content)
Multiple MCP Servers
mcp_config = {
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "/workspace"]
},
"web": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-fetch"]
},
"memory": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-memory"]
}
}
}
agent = FnCallAgent(
function_list=[mcp_config],
llm={'model': 'qwen-max'}
)
SSE Server
