C# MCP Server Testing

Test MCP servers at two levels: unit tests for individual tool methods, and integration tests that exercise the full MCP protocol in-memory.

When to Use

• Adding automated tests to an MCP server
• Testing individual tool methods with mocked dependencies
• Writing integration tests that validate tool listing and invocation via MCP protocol
• Setting up CI test pipelines for MCP servers

Stop Signals

• No server yet? → Use mcp-csharp-create first
• Server not running? → Use mcp-csharp-debug
• Just need manual/interactive testing? → Use mcp-csharp-debug for MCP Inspector
