Build and integrate MCP servers and clients with the official C# SDK.
This appears to be an official open-source C# SDK on GitHub with strong community adoption, which materially lowers overall risk. The materials show no required secrets and no declared remote endpoints, but it still has code-execution-related capability, so standard local isolation and least-privilege controls are advisable.
The materials explicitly state that no keys or environment variables are required. No API tokens, account credentials, or other sensitive authentication data are requested, so credential exposure and abuse risk appears low.
No remote endpoint host is declared in the materials, and there is no described behavior of sending user data to third-party services. Based on the available facts, no explicit data egress path is identified.
The system checks indicate executes-code capability. As an MCP SDK, its normal use may involve running local code or supporting server/client processes. This is an inherent capability for this class of tool, and the provided materials do not show requests for unusually dangerous system privileges beyond its stated purpose.
The materials do not explicitly enumerate file or data access scope, but as a local SDK/tool it may normally interact with development directories, project files, or runtime inputs/outputs. No excessively broad data permissions are evident from the materials, but least-privilege use is still appropriate.
The source is an official open-source GitHub repository, described as the official C# SDK for Model Context Protocol and maintained in collaboration with Microsoft. Community adoption is relatively strong (~4.3k stars), and the source is auditable, all of which materially reduce supply-chain risk. The license and maintenance activity are not explicit in the materials and should be verified, but that alone does not justify a high-risk rating.

No copy-paste install info for "csharp-sdk" yet — see the docs or source repo.
Using C# and the csharp-sdk, create a minimal runnable MCP server example that exposes a tool named get_weather returning mock weather data, and explain the project structure, dependency installation, and startup steps.
Runnable C# MCP server sample code with tool definition, dependency notes, and run instructions.
Use the csharp-sdk to write a C# MCP client example that connects to a local MCP server, lists available tools, calls the get_weather tool, outputs the result, and includes basic error handling.
A C# client sample showing connection, tool discovery, tool invocation, and exception handling.
I want to wrap an existing internal C# service as MCP tools. Using the csharp-sdk, design an example that exposes two methods—check order status and create support ticket—as MCP tools, and provide parameter models, response structures, and security considerations.
