Question 2

What security considerations should I be aware of?

Accepted Answer

Context7 offers both local (npx) and remote connection options: Remote Option: Uses Context7's hosted service, which is more secure and requires no local execution Local Option: Runs via npx on your machine with outbound API calls API Key Required: Both options require a Context7 API key for authentication Security note: The remote option at `https://mcp.context7.com/mcp` is recommended for enhanced security as it doesn't require local code execution—only authenticated API calls to fetch documentation.
