Security Risks and Best Practices

Connecting any data source to LLMs carries inherent risks, especially when it stores sensitive data. ChatTempMail is no exception, so it's important to understand the risks you should be aware of and the additional precautions you can take to mitigate these risks.

Prompt Injection

The primary attack vector unique to LLMs is prompt injection, where LLMs may be tricked into following untrusted commands in user content.

Important Note: Most MCP clients (such as Cursor) require you to manually approve each tool call before execution. We recommend you always keep this setting enabled and always review the details before executing tool calls.

Recommendations

To mitigate security risks when using the ChatTempMail MCP server, we recommend adopting the following best practices:

Don't connect to production data: Use the MCP server with test data, not production data. LLMs are excellent at helping design and test applications, so leverage them in a safe environment without exposing real data.

Don't provide to customers: The MCP server runs in your developer permission context, so it should not be provided to your customers or end users. Instead, use it as an internal developer tool to help you build and test applications.

API key protection: Store API keys securely in environment variables and never expose them in public repositories or client-side code.

Regular cleanup: Set up automatic cleanup of expired emails and regularly delete unused temporary emails.

Monitor usage: Monitor API usage for suspicious activity and implement appropriate error handling and retry logic.

Supported MCP Clients

The ChatTempMail MCP server is compatible with the following MCP-supported clients:

Cursor
Windsurf (Codium)
Visual Studio Code (Copilot)
Cline (VS Code extension)
Claude desktop
Claude code
Amp

Resources

Notes

Please set the API key as the environment variable TEMPMAIL_API_KEY. Be careful not to lose it, and do not leak it in public places
The base URL can be customized via the environment variable TEMPMAIL_BASE_URL (default is https://chat-tempmail.com)
Temporary email addresses will automatically expire according to the set expiration time
Use nextCursor in paging queries to get more data
Ensure environment variables are correctly set in the MCP client configuration file

How to pay the difference when upgrading from VIP to SVIP on the website?

Selenium39 — Thu, 22 May 2025 10:00:21 +0000

I'm adding a payment feature to my website https://chat-tempmail.com, and I've chosen creem.io as the payment tool. While coding, I encountered an issue:

For example, my VIP costs $5, and SVIP costs $10. When upgrading from VIP to SVIP, the user should only pay the price difference of $5.

Should I:

Create a dedicated "price difference" product for this case?
Pass a fixed discount code when creating the order?
Or is there another approach to handle this?

Looking for the best practice to implement this logic.
