Questions

What is the GEmojiSharp MCP server?

:octocat: GitHub Emoji for C#, dotnet and beyond

Is GEmojiSharp safe to connect to an agent?

No — not without reading the findings first. The audit graded it D (69/100) and found 3 critical or high issues in the source. Each one is listed on this page with the file and line it is on.

What credentials does GEmojiSharp need?

No credential environment variables were found in its source, so it appears to need none.

How does GEmojiSharp run?

It speaks stdio, so it runs as a local process your client starts.

How current is this page?

The grade is for one exact copy of the source (fa6573299cba), read on 2026-10-07. The repository is watched and re-audited when it changes.
