Verify Microsoft SDK methods, find working code samples, and catch hallucinated APIs against official docs. Three core tools: microsoft_docs_search for API lookups, microsoft_code_sample_search for working examples in C#/Python/JavaScript, and microsoft_docs_fetch for full reference pages with overloads Catches common mistakes like wrong method signatures, deprecated patterns, mismatched SDK versions (v11 vs v12), and incorrect package names Works with Azure SDKs, .NET libraries, and... npx skills add https://github.com/github/awesome-copilot --skill microsoft-code-reference Download ZIPGitHub36.2k

Microsoft Code Reference

Tools

Need Tool Example API method/class lookup microsoft_docs_search "BlobClient UploadAsync Azure.Storage.Blobs" Working code sample microsoft_code_sample_search query: "upload blob managed identity", language: "python" Full API reference microsoft_docs_fetch Fetch URL from microsoft_docs_search (for overloads, full signatures)

Finding Code Samples

Use microsoft_code_sample_search to get official, working examples:

microsoft_code_sample_search(query: "upload file to blob storage", language: "csharp")
microsoft_code_sample_search(query: "authenticate with managed identity", language: "python")
microsoft_code_sample_search(query: "send message service bus", language: "javascript")

When to use:

• Before writing code—find a working pattern to follow

• After errors—compare your code against a known-good sample

• Unsure of initialization/setup—samples show complete context

API Lookups

# Verify method exists (include namespace for precision)
"BlobClient UploadAsync Azure.Storage.Blobs"
"GraphServiceClient Users Microsoft.Graph"

# Find class/interface
"DefaultAzureCredential class Azure.Identity"

# Find correct package
"Azure Blob Storage NuGet package"
"azure-storage-blob pip package"

Fetch full page when method has multiple overloads or you need complete parameter details.

When to Verify

Always verify when:

• Method name seems "too convenient" (UploadFile vs actual Upload)

• Mixing SDK versions (v11 CloudBlobClient vs v12 BlobServiceClient)

• Package name doesn't follow conventions (Azure.* for .NET, azure-* for Python)

• Using an API for the first time

Validation Workflow

Before generating code using Microsoft SDKs, verify it's correct:

• Confirm method or package exists — microsoft_docs_search(query: "[ClassName] [MethodName] [Namespace]")

• Fetch full details (for overloads/complex params) — microsoft_docs_fetch(url: "...")

• Find working sample — microsoft_code_sample_search(query: "[task]", language: "[lang]")

For simple lookups, step 1 alone may suffice. For complex API usage, complete all three steps.

CLI Alternative

If the Learn MCP server is not available, use the mslearn CLI from a terminal or shell (for example, Bash, PowerShell, or cmd) instead:

# Run directly (no install needed)
npx @microsoft/learn-cli search "BlobClient UploadAsync Azure.Storage.Blobs"

# Or install globally, then run
npm install -g @microsoft/learn-cli
mslearn search "BlobClient UploadAsync Azure.Storage.Blobs"

MCP Tool CLI Command microsoft_docs_search(query: "...") mslearn search "..." microsoft_code_sample_search(query: "...", language: "...") mslearn code-search "..." --language ... microsoft_docs_fetch(url: "...") mslearn fetch "..."

Pass --json to search or code-search to get raw JSON output for further processing.
