How do I connect to the MCPHub server?

[SharkByte-Pray]

I am currently using the open-source project mcphub, and I would like to integrate it with Flowise. However, despite consulting both the Flowise and mcphub documentation, I have been unable to find a method to do so. I am unsure how to proceed; could you please advise?

The MCPHUB address points to another local computer of mine; I am able to access this MCPHUB using Cherry-Studio.

Hi @SharkByte-Pray, It seems that your URL is denied by default. This is security issue. You can take a look a list of denied URL below:
https://github.com/FlowiseAI/Flowise/blob/main/packages/components/src/httpSecurity.ts#L16

Do you use Flowise Cloud or self-host instance? If you self host the Flowise instance, you can add the environment below to bypass this for testing (not recommended for production)
HTTP_SECURITY_CHECK=false

Thank you for the explanation.

你好@SharkByte-Pray您的 URL 似乎默认被拒绝访问。这是一个安全问题。您可以查看以下被拒绝的 URL 列表： https://github.com/FlowiseAI/Flowise/blob/main/packages/components/src/httpSecurity.ts#L16

您使用的是 Flowise Cloud 还是自托管实例？如果您自托管 Flowise 实例，则可以添加以下环境以绕过此限制进行测试（不建议用于生产环境）。 HTTP_SECURITY_CHECK=false

I'm using a self-hosted system; I'll try changing the environment variables.
