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 5.1 | $0.03785 | $0.03785 |
| Opus 5 | $0.01893 | $0.01893 |
| Sonnet 5 | $0.00757 | $0.00757 |
| Haiku 4.5 | $0.00379 | $0.00379 |
Grade A, and why
weixin-devtools-mcp 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 408 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Overview
微信开发者工具自动化 MCP 服务器，共实现 31 个工具用于微信小程序的自动化测试。基于 TypeScript 和 miniprogram-automator SDK 实现。
工具暴露按 profile 裁剪（见
src/config/tool-profile.ts）：默认coreprofile 仅暴露 20 个核心工具；minimal暴露 10 个；通过--tools-profile=full（或环境变量WEIXIN_MCP_TOOLS_PROFILE=full）可启用全部 31 个工具（含 console / network / screenshot / diagnose 类）。也可用--enable-categories/--disable-categories按类别精细控制。
Common Commands
开发和构建
# 构建项目（TypeScript → JavaScript + 设置可执行权限）
npm run build
# 开发模式（监听文件变化自动重新构建）
npm run watch
# 使用 MCP Inspector 调试
npm run inspector
测试
项目采用分层测试架构，参考 chrome-devtools-mcp 模式：
tests/
├── protocol/ # 协议层测试（需要MCP服务器）
│ ├── server.test.ts
│ └── index.test.ts
├── tools/ # 工具逻辑测试（直接调用handler，无需服务器）
│ ├── connection.test.ts
│ ├── console.test.ts
│ ├── navigate.test.ts
│ ├── network.test.ts
│ ├── page.test.ts
│ └── screenshot.test.ts
├── integration/ # 集成测试（需要真实环境）
│ ├── connect-devtools.integration.test.ts
│ ├── console.integration.test.ts
│ ├── enhanced-connection.integration.test.ts
│ ├── navigation.integration.test.ts
│ ├── network.integration.test.ts
│ └── network-auto-start.integration.test.ts
└── utils/ # 测试工具
└── test-utils.ts
测试命令：
# 单元测试（协议 + 工具 + 工具类，224个测试）
npm test
# 分类运行单元测试
npm run test:protocol # 协议层测试（19个）
npm run test:tools # 工具逻辑测试（196个）
# 集成测试（需要微信开发者工具 + playground/wx/）
npm run test:integration # 46个集成测试
# 所有测试（单元 + 集成）
npm run test:all
# 测试覆盖率
npm run test:coverage
# 监听模式
npm run test:watch # 单元测试监听
npm run test:integration:watch # 集成测试监听
集成测试要求：
- 微信开发者工具已安装并开启自动化功能
- 测试项目位于
playground/wx/ - 通过环境变量
RUN_INTEGRATION_TESTS=true控制执行 - 不设置该环境变量时，集成测试会自动跳过
运行单个测试
# 协议测试
npx vitest tests/protocol/server.test.ts
# 工具测试
npx vitest tests/tools/console.test.ts
# 集成测试
RUN_INTEGRATION_TESTS=true npx vitest tests/integration/console.integration.test.ts
# 指定测试用例
npm test -- tests/tools/console.test.ts -t "测试用例名称"
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-devtools-mcp CLAUDE.md is an instructions file published in the GitHub repository wooter-s/weixin-devtools-mcp (78 stars, last pushed yesterday), licensed MIT. It adds 3,785 tokens to every session, about $0.0189 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.
