dmg

[joeblew999]

I downloaded the release dmg from https://github.com/smart-mcp-proxy/mcpproxy-go/releases/tag/v0.3.19.

then installed it and then allowed the Mac to open it ( via security settings, since it's not signed) but nothing. Just hangs.

So then went inside the .app to run the golang binary and:

apple@apples-MacBook-Pro ~ % /Applications/mcpproxy.app/Contents/MacOS/mcpproxy ; exit;

it just hangs. no GUI starts up in taskbar...

2nd attempt did not change anything...

Smart MCP Proxy is running as I can see it in the Activity Monitor, but seems the Taskbar GUI is not opening ...

[joeblew999]

if you need more data just shout, but will not dive deeper for now.

Thanks for the detailed report!

Unfortunately, I can’t reproduce the issue locally, and based on the logs, nothing immediately stands out.

Here are some suggestions that might help:

1. Install via Homebrew
   Please try installing the app using Homebrew, which avoids macOS security prompts and runs more smoothly:

   brew install smart-mcp-proxy/mcpproxy/mcpproxy

2. If the issue still persists, try debugging it this way:

Check if port 8080 is free:

lsof -i :8080

No output means the port is free. If it’s in use, you can specify a different port:

mcpproxy --listen :8081

Enable debug logging:

mcpproxy --log-level debug --listen :8081

Test endpoint with curl:

curl -X POST http://localhost:8081/mcp/ \
     -H "Content-Type: application/json" \
     -d "{}"

A healthy response should say: "Invalid session ID".

If this still doesn’t work, could you share your macOS version? You can get it with: uname -v

Also, I’m actively working on code-signing and notarizing the DMG builds. A properly signed installer should be available in the next few days, which should remove any security-related friction.

Thanks again for your feedback!

DMG installers are now properly signed and available for download:

mcpproxy-0.3.26-darwin-arm64.dmg
mcpproxy-0.3.26-darwin-amd64.dmg
