roslyn

roslyn is an MCP server for Claude Code from zdanovichnick/dotnet-pilot. Its token cost is not measured, scanned A, original, MIT.

An MCP server that provides Roslyn-based analysis for .NET projects. Roslyn is Microsoft's technology for reading and understanding C# code.

In plain words
What is it for?
Use it as the code-analysis service behind .NET development tasks; it requires the configured `dnp-roslyn` command and two environment settings.
Why use it?
It lets compatible coding-agent tools inspect a .NET solution using information about the code's meaning, not only its text.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

roslyn scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
