dotnet-mcp-server SKILL.md skillA
dotnet-mcp-server from arasz/ai-badger is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add arasz/ai-badger/dotnet-mcp-server@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Use when adding MCP (Model Context Protocol) tools or servers to a .NET project: tool/prompt registration with [McpServerTool]/[McpServerPrompt], stdio or Streamable-HTTP host wiring (dual-mode, port traps), DI + typed HttpClient for REST-backed tools, unit tests with mock HTTP handlers, tool-inventory tests that assert the REGISTERED surface, and SDK 2.x specifics (McpException error signaling, request filters, tool-name derivation).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# dotnet-mcp-server
Implement MCP servers in .NET using the `ModelContextProtocol` NuGet package (SDK v1.4+).
## Prerequisites
- .NET 10+ (the SDK targets `net10.0` but works on `net8.0`+)
- NuGet packages: `ModelContextProtocol`, `Microsoft.Extensions.Hosting`
- For HTTP-calling tools: `Microsoft.Extensions.Http`
## 1. Project setup
```xml
<!-- .csproj -->
<PropertyGroup>
<OutputType>Exe</OutputType>
<PackAsTool>true</PackAsTool>
<PackageType>McpServer</PackageType>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.Extensions.Hosting" />
<PackageReference Include="Microsoft.Extensions.Http" /> <!-- for REST-calling tools -->
<PackageReference Include="ModelContextProtocol" />
</ItemGroup>
<!-- Let tests access internal tool classes -->
<ItemGroup>
<InternalsVisibleTo Include="YourProject.Mcp.Tests" />
</ItemGroup>
```
## 2. Tool class pattern
Tools are **plain C# classes** annotated with `[McpServerTool]` and `[Description]`. The MCP SDK discovers them via DI.
```csharp
using System.ComponentModel;
using System.Net.Http.Json;
using System.Text.Json;
using ModelContextProtocol.Server;
namespace YourProject.Mcp.Tools;

How to install
mdr add arasz/ai-badger/dotnet-mcp-server@sha256:8a9a601288251847The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
