Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add instructions/dcatfly/weixin_claude_code/claude-mdgit clone --depth 1 https://github.com/Dcatfly/weixin_claude_codeWhat it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00583 | $0.00583 |
| Opus 5 | $0.00292 | $0.00292 |
| Sonnet 5 | $0.00117 | $0.00117 |
| Haiku 4.5 | $0.00058 | $0.00058 |
Grade A, and why
weixin_claude_code CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
weixin-claude-code
微信 Channel for Claude Code — MCP 适配层,依赖 weixin-bot-plugin 库实现微信通信。
命令
bun run build # 编译(bun build 打包为单文件 dist/index.js)
bun run start # 启动 MCP 服务器(自动安装依赖)
bun run typecheck # TypeScript 类型检查
bun run dev # 开发模式(tsc --watch)
架构
src/
├── index.ts # 入口:创建 WeixinBotClient + MCP Server,事件绑定 + 权限拦截
└── mcp-server.ts # MCP Channel 服务器,注册 reply/login/logout/status 工具,权限转发
# weixin-bot-plugin npm 包,独立微信通信库,源码在 ../weixin_bot_plugin/
本项目仅包含 Claude Code MCP 协议适配层。微信通信功能(API、认证、CDN、媒体、消息收发、poll-loop)
全部由 weixin-bot-plugin 库提供。
关键设计
- MCP stdio 服务器,声明
claude/channelcapability,消息通过 notification 推送 - 通过
WeixinBotClient的 EventEmitter 事件接收微信消息,转发为 MCP notification - 权限转发:Claude Code 权限请求 → 微信文本 → 用户回复 yes/no → 权限审批 notification
- 权限回复拦截(
PERMISSION_REPLY_RE)保留在此层,是 Claude Code 特有概念 - 凭证存储路径通过
stateDir配置,向后兼容~/.claude/channels/wechat/ vendor/目录已移至../weixin_bot_plugin/vendor/,本项目不再包含
插件发布
.claude-plugin/包含插件清单,.mcp.json使用${CLAUDE_PLUGIN_ROOT}dist/预编译后提交到 git,用户安装插件后无需编译start脚本中bun install确保运行时依赖就绪bun build会将weixin-bot-plugin打包进单文件,分发时不依赖外部路径
注意事项
contextToken是每条消息的会话令牌,由weixin-bot-plugin内部管理- session 过期(errcode -14)后需要用户手动重新 login,不会自动恢复
- Typing 状态由本层在收到消息时手动 start,reply 时手动 stop
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

weixin_claude_code CLAUDE.md is an instructions file published in the GitHub repository Dcatfly/weixin_claude_code (57 stars, last pushed 5mo ago), licensed MIT. It adds 583 tokens to every session, about $0.0029 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
