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 | $0.01566 | $0.01566 |
| Opus 5.5 | $0.00626 | $0.00626 |
| Sonnet 5.5 | $0.00313 | $0.00313 |
| Haiku 4.5 | $0.00157 | $0.00157 |
Grade A, and why
cc-3-8-x-mcp AGENTS.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 1mo 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 — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
本文是 cc-3-8-x-mcp 的 agent 使用规则。它只支持 Cocos Creator 3.8.x;项目自己的预览参数、业务本地服地址、测试账号和验证步骤写在项目文档里。
允许入口
使用本插件时,只允许从下面这些入口进入:
| 入口 | 用途 |
|---|---|
全局 cocos-mcp-gateway 注入的项目 tool |
scene / asset-db / preview / local 域操作 |
cocos-mcp-cli offline 命令 |
.prefab / .anim 文件查询和修改 |
| Playwright / Chrome | 浏览器里真实游戏页面的交互验证 |
temp/refresh 的 restart-package |
重启本扩展代码 |
项目扩展的 /bridge 是 Gateway 私有协议,agent 和其他 MCP 客户端不得直接调用、不得直接读取或复制注册记录中的 token。其它入口不作为本插件使用路径。
绑定当前项目
同机可能同时打开多个 Cocos 项目。agent 必须先按项目根目录绑定 MCP 实例,再执行后续操作。
实例注册文件:
~/.cocos-mcp/editors/*.json
绑定规则:
- 扫描
~/.cocos-mcp/editors/*.json。 - 只保留
projectPath与当前项目根目录一致的记录。 - 校验
pid仍存活。 - 多个匹配时取
updatedAt最新的记录。 - 只接受
transport=editor-bridge、gatewayApiVersion>=2、bridgeApiVersion=1的记录。 - 后续操作只调用 Gateway 暴露的
<project>__<tool>,不直接请求记录中的/bridgeURL。 - 缺失或格式不正确的
authToken视为无效注册记录;token 不写日志、不贴到回复里。

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.
