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" }
    },
    "weixin-work": {
      "command": "npx",
      "args": ["weixin-mcp", "start", "--port", "3002"],

TDQS

A3.9/5.0

Scored across 7 tools

Disambiguation5/5

Each tool has a distinct purpose: polling, contacts, sending different content types, config retrieval, and media download. The send variants are clearly differentiated by content type (text, image, file), and no two tools overlap.

Naming Consistency4/5

All tool names share the weixin_ prefix and use snake_case, but the pattern is not strictly verb_noun: weixin_contacts is a noun, and weixin_poll/weixin_send are bare verbs. Overall readable and predictable, with minor deviations.

Tool Count5/5

7 tools is well within the ideal range for a focused WeChat bot server, covering incoming messages, contacts, outgoing messages, config, and media download without redundancy.

Completeness4/5

Core send/receive workflows are covered, including text/image/file sending and media download. A minor gap exists: the config tool mentions a typing_ticket for sendTyping, but no send_typing tool is present.
