WEIXIN_MCP_DIR=~/.weixin-mcp-a npx weixin-mcp start --port 3001

# 实例 B(端口 3002)
WEIXIN_MCP_DIR=~/.weixin-mcp-b npx weixin-mcp login
WEIXIN_MCP_DIR=~/.weixin-mcp-b npx weixin-mcp start --port 3002

Claude Desktop 配置多账号:

    "weixin-personal": {
      "command": "npx",
      "args": ["weixin-mcp", "start", "--port", "3001"],
      "env": { "WEIXIN_MCP_DIR": "/Users/you/.weixin-mcp-personal" }
