Add NuGet package metadata and assets for Microsoft.DataApiBuilder.Mcp

[anushakolan]

Why make this change?

Closes : #3658

DAB currently publishes two NuGet packages:

• Microsoft.DataApiBuilder — full engine
• Microsoft.DataApiBuilder.Core — modular core library

Partner teams need to consume MCP functionality directly from a .NET application without hosting the full DAB engine. There was no dedicated package for this.

This change introduces Microsoft.DataApiBuilder.Mcp so teams can embed and host DAB MCP endpoints in their own ASP.NET Core applications, consuming it as an SDK dependency.

Current scope is internal Azure Artifacts feed only. NuGet.org publishing is not included in this change.

What is this change?

1. Updated Azure.DataApiBuilder.Mcp.csproj

Added full NuGet package authoring metadata:

• PackageId, Title, Authors, Copyright
• Description, PackageTags, AssemblyName
• PackageLicenseFile, PackageIcon, PackageReadmeFile
• PackageProjectUrl, RepositoryType
• EmbedUntrackedSources, PublishRepositoryUrl for Source Link support
• ContinuousIntegrationBuild conditional on TF_BUILD for deterministic pipeline builds
• PackageOutputPath set to ./nupkg
• Pack asset wiring for README, icon, LICENSE, and conditional NOTICE

2. Added nuget/nuget_mcp/README.md

Package-specific readme for Microsoft.DataApiBuilder.Mcp following the same structure as nuget/nuget_core/README.md, including:

• License badge
• Package purpose and intended audience
• Key capabilities
• Installation and usage guidance
• Internal distribution scope note
• Resource links

How was this tested?

Local pack validation

dotnet pack src/Azure.DataApiBuilder.Mcp/Azure.DataApiBuilder.Mcp.csproj -c Release -o artifacts/mcp-verify

Pack succeeded and produced Microsoft.DataApiBuilder.Mcp.2.0.0.nupkg.

Package contents verified

Opened nupkg as archive and confirmed:

• lib/net8.0/Microsoft.DataApiBuilder.Mcp.dll — correct assembly name
• README.md — from nuget/nuget_mcp/README.md
• LICENSE.txt — from repo root
• nuget_icon.png — from nuget/nuget_icon.png
• Microsoft.DataApiBuilder.Mcp.nuspec — generated with all metadata

Nuspec metadata verified

Confirmed all required fields populated:

• id, version, authors, description, tags, projectUrl, repository, icon, readme, license file

Dependency graph verified

Confirmed correct transitive dependencies declared in nuspec for net8.0:

• Microsoft.DataApiBuilder.Core
• ModelContextProtocol
• ModelContextProtocol.AspNetCore

Pull request overview

This PR makes the Azure.DataApiBuilder.Mcp project packable as a standalone NuGet package (Microsoft.DataApiBuilder.Mcp) by adding NuGet authoring metadata and wiring in the required package assets (README/icon/license, plus conditional NOTICE support), enabling partner teams to consume MCP functionality without hosting the full DAB engine.

Changes:

• Added NuGet package metadata and deterministic CI packing settings to Azure.DataApiBuilder.Mcp.csproj.
• Added package asset packing for README, icon, LICENSE, and a conditional NOTICE file.
• Introduced a package-specific README under nuget/nuget_mcp/ describing purpose and usage.
