Update MCP template for new registry specification

[Copilot]

Updates the MCP server template to align with the new Model Context Protocol registry specification. The MCP registry has updated its server.json schema, requiring several property name changes and structural modifications for successful package ingestion.

Changes Made

The following updates were applied to both the main template and test snapshot files:

• Root level changes:

  • Kept name property (root identifier remains unchanged)
  • Moved version from nested version_detail object to root level
  • Removed the version_detail wrapper object

• Package configuration updates:

  • Changed registry_name → registry_type
  • Changed name → identifier for package identification
  • Added required transport property with {"type": "stdio"} configuration

• Schema URI updates:

  • Updated from https://modelcontextprotocol.io/schemas/draft/2025-07-09/server.json
  • To https://static.modelcontextprotocol.io/schemas/2025-07-09/server.schema.json
  • Removed /draft/ from path and updated filename to server.schema.json

Updated Structure

The template now follows this format aligned with the registry specification:

{
  "$schema": "https://static.modelcontextprotocol.io/schemas/2025-07-09/server.schema.json",
  "name": "io.github.<your GitHub username here>/<your repo name>",
  "version": "0.1.0-beta",
  "packages": [
    {
      "registry_type": "nuget",
      "identifier": "<your package ID here>",
      "version": "0.1.0-beta",
      "transport": {
        "type": "stdio"
      },
      "package_arguments": [],
      "environment_variables": []
    }
  ]
}

Files Modified

• src/ProjectTemplates/Microsoft.Extensions.AI.Templates/src/McpServer/McpServer-CSharp/.mcp/server.json
• test/ProjectTemplates/Microsoft.Extensions.AI.Templates.IntegrationTests/Snapshots/mcpserver.Basic.verified/mcpserver/.mcp/server.json

These changes ensure that MCP server projects created from this template will successfully publish to the MCP registry using mcp-publisher without encountering missing property errors.

Fixes #5467

Sorry @copilot -- the root "name" property should still be named name

Fixed! Changed the root property back to name instead of id. All other registry specification updates remain in place. See commit fc6cf7f.
