    "time-server": {
      "command": "dotnet",
      "args": [
        "run", 
        "--project",

Publishing New Versions

To publish a new version of the package:

• Update the version in TimeMcpServer.csproj, and commit as Release x.y.z

• Tag the release with a version number prefixed with 'v':

  git tag v1.0.1
  

• Push the tag to trigger the publishing pipeline:

  git push --tags
  

Then the CI/CD pipeline will automatically publish the package.

CI/CD

The project includes GitHub Actions workflows for:

• Build & Test - Builds and tests on multiple platforms (Windows, macOS, Linux)
• Publish - Automatically publishes to NuGet and creates GitHub releases on version tags
