SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires xunit, moq, fluentassertions, modelcontextprotocol, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill automates testing and verification of C# MCP servers, streamlining the process of unit testing tool methods and integration testing with in-memory MCP client/server scenarios.

Core Features & Use Cases

  • Unit Testing: Test individual tool methods for correct functionality.
  • Integration Testing: Validate tool invocation via MCP protocol, setting up CI test pipelines.
  • In-Memory Testing: Zero-network integration tests with ClientServerTestBase.
  • HTTP Testing: Use WebApplicationFactory for testing HTTP MCP servers.
  • Evaluation Setup: Create evaluations for measuring tool quality and writing eval questions.

Quick Start

Run unit tests for the C# MCP server with dotnet test.

Frequently Asked Questions about mcp-csharp-test

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate C# MCP server testing for tool methods?▼

Automate C# MCP server testing by running unit tests for individual tool methods using xUnit and FluentAssertions, validating correct functionality via `dotnet test`.

How does in-memory integration testing work for MCP servers?▼

In-memory integration testing for MCP servers uses `ClientServerTestBase` to validate tool invocation via the MCP protocol with zero network overhead, streamlining CI test pipelines.

Can I test HTTP MCP servers using WebApplicationFactory?▼

Yes, you can test HTTP MCP servers using `WebApplicationFactory` to validate tool invocation over HTTP, complementing the zero-network in-memory integration tests.

Do I need Moq and FluentAssertions to set up C# MCP server evaluations?▼

Yes, setting up C# MCP server evaluations requires Moq and FluentAssertions, along with the ModelContextProtocol client SDK, to measure tool quality and write eval questions.

What is the best way to verify MCP client SDK integration in C#?▼

The best way to verify MCP client SDK integration in C# is running integration tests via the ModelContextProtocol client SDK to validate tool invocation through the MCP protocol.

Why use xUnit for C# MCP server unit testing instead of other frameworks?▼

Use xUnit for C# MCP server unit testing to streamline CI pipelines and validate individual tool methods, pairing with Moq for mocks and FluentAssertions for assertions.
