🐛 问题描述

我根据项目所提供的cloudflare部署文档，尝试在cloudflare部署NextChat
我首先保持使用如下推荐的环境变量进行了配置：
NODE_VERSION=20.1
NEXT_TELEMETRY_DISABLE=1
OPENAI_API_KEY=我的APIkey
YARN_VERSION=1.22.19
PHP_VERSION=7.4
BASE_URL=我的baseurl

在首次部署后，我为了使用mcp功能，按照下列新的环境变量，重新进行了部署：
我在worker 中 使用了新的环境变量：
NODE_VERSION=20.1
NEXT_TELEMETRY_DISABLE=1
YARN_VERSION=1.22.19
PHP_VERSION=7.4
ENABLE_MCP=true
然后重新部署

然而意外的是重新部署后的cloudflare page并没有MCP按钮
同时我在浏览器日志中发现了：
page-11392df71ff8766e.js:1 [SideBar] MCP enabled: undefined

疑似是MCP enabled环境获取失误

（很抱歉我不知道这属于NextChat的问题还是Cloudflare worker/page的问题，所以在这里发了这个issues，希望作者和各位前辈能提供帮助）

🐛 Question description

I'm trying to deploy NextChat in cloudflare based on the cloudflare deployment documentation provided by the project (https://github.com/ChatGPTNextWeb/NextChat/blob/main/docs/cloudflare-pages-cn.md)
I first kept configuring using the recommended environment variables below:
NODE_VERSION=20.1
NEXT_TELEMETRY_DISABLE=1
OPENAI_API_KEY=My APIkey
YARN_VERSION=1.22.19
PHP_VERSION=7.4
BASE_URL=My baseurl

After the first deployment, I re-deployed following the new environment variables in order to use the mcp function:
I've used a new environment variable in the worker:
NODE_VERSION=20.1
NEXT_TELEMETRY_DISABLE=1
YARN_VERSION=1.22.19
PHP_VERSION=7.4
ENABLE_MCP=true
Then redeploy

However, unexpectedly, the cloudflare page after redeployment does not have an MCP button
At the same time, I found in the browser log:
page-11392df71ff8766e.js:1 [SideBar] MCP enabled: undefined

It is suspected that it is an error in obtaining the MCP enabled environment

(I'm sorry I don't know if this is a problem with NextChat or a problem with Cloudflare worker/page, so I posted this issue here, I hope the author and all the predecessors can help)
