- name: Debug an MCP server with MCP Inspector
|
|
prompt: |
|
|
I have a C# MCP server that uses stdio transport. I want to test it
|
|
interactively with the MCP Inspector to see if my tools are working.
|
|
How do I connect and debug?

rubric:
|
|
- Shows how to launch MCP Inspector with npx @modelcontextprotocol/inspector
|
|
- Explains how to connect it to the stdio server using dotnet run — either as a single CLI command (npx
|
|
@modelcontextprotocol/inspector dotnet run ...) or via the Inspector UI configuration (Transport Type, Command,
|
|
Arguments)
|
|
- Mentions that the Inspector UI shows tools, prompts, and resources
|
|
- Notes that server logging must go to stderr, not stdout
|

- name: Configure VS Code to use an MCP server
|
|
prompt: |
|
|
I built a C# MCP server at src/MyMcpServer/MyMcpServer.csproj.
|
|
I want to use it with GitHub Copilot in VS Code agent mode.
|
|
How do I configure mcp.json?

- Shows the mcp.json configuration with type stdio
|
|
- Uses dotnet run --project with the correct project path
|

- Places the config in .vscode/mcp.json for workspace or user settings
|
|
- Mentions testing the configuration by asking Copilot to use the tools
|
|
- name: Debug a failing MCP server tool
|
|
prompt: |
|
|
My C# MCP server is returning errors when I call one of its tools from
|
|
VS Code Copilot. The tool works fine when I run it manually as a console
|
|
app. How do I debug this?

|
|
rubric:
|
|
- Explains that stdout is reserved for MCP protocol in stdio mode
|
|
- Recommends checking that all logging goes to stderr
|
|
- Shows how to further diagnose the issue — such as attaching a debugger to the running process, using
|
|
Debugger.Launch(), or configuring launch.json to debug the server
|
|
- Suggests using MCP Inspector or VS Code debug config to test or step through the server
