Questions
What is the DotNet MCP server?
MCP wrapper for the .NET SDK
Is DotNet safe to connect to an agent?
No — not without reading the findings first. The audit graded it D (65/100) and found 2 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 DotNet need?
No credential environment variables were found in its source, so it appears to need none.
How does DotNet 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 (f15a30429725), read on 2026-10-08. The repository is watched and re-audited when it changes.
