MCP template should use token replacement for id in server.json

[timheuer]

Description

In the .mcp/server.json there is an identifier that has a placeholder <your package ID here> -- this really should use the sourceName property of the template which would get the automatic replacement value and mirror what is used in the PackageId in the csproj.

Changing <your package ID here> to McpServer-CSharp will do the trick as that is the sourceName -- PackageId should be changed too.

Reproduction Steps

Create a new project with the template named "TimFooBar"

Expected behavior

PackageId defaults to the project name. This is common templating behavior.

Actual behavior

Hard-coded to SampleMcpServer

Regression?

No

Known Workarounds

Manually change it

Configuration

I didn't do this original since I wanted people to be more thoughtful about their package ID. Parent dir name, csproj name, assembly name etc may not always match the package ID and the package ID is what will get baked into consumers config. We could make package ID a separate parameter, or do exactly as you say here in the issue. I don't feel too strongly, just wanted to share my thinking.
