Feature request: Support proxy (HTTP/HTTPS/SOCKS) for memo MCP

[augviolet]

Hi! Thanks for the awesome project 🙏
On Windows with npx -y @upstash/memo, memo get works but memo set fails with “Network error”.
When I switch my proxy app to TUN mode, it works, so it seems the MCP process does not use system proxy nor HTTP_PROXY env vars.
Could you please add proxy support (e.g., --proxy flag or respect HTTP_PROXY/HTTPS_PROXY/ALL_PROXY)?

Environment

• OS: Windows
• MCP client: Cursor
• Run: npx -y @upstash/memo
• Proxy: Clash Verge (HTTP proxy http://127.0.0.1:7890)
• Status: System proxy mode fails, TUN works

Repro

1. Enable system proxy (no TUN)
2. Start MCP via npx -y @upstash/memo
3. Run memo set
4. Error: Network error
5. Switch to TUN → works

Expected

• Support --proxy http://127.0.0.1:7890
• Or read HTTP_PROXY/HTTPS_PROXY/ALL_PROXY
• Windows friendly proxy handling
