npx skills add microsoftdocs/mcp --skill microsoft-code-reference
Find working code samples, verify API signatures, and fix Microsoft SDK errors using official docs. Use whenever the user is writing, debugging, or reviewing code that touches any Microsoft SDK, .NET library, Azure client library, or Microsoft API—even if they don't ask for a "reference." Catches hallucinated methods, wrong signatures, and deprecated patterns. If the task involves producing or fixing Microsoft-related code, this is the right skill.

| 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) |
Use microsoft_code_sample_search to get official, working examples:
When to use:
Fetch full page when method has multiple overloads or you need complete parameter details.
Use microsoft_code_sample_search to find working code samples and compare with your implementation. For specific errors, use microsoft_docs_search and microsoft_docs_fetch:
| Error Type | Query |
|---|---|
| Method not found | "[ClassName] methods [Namespace]" |
| Type not found | "[TypeName] NuGet package namespace" |
| Wrong signature | "[ClassName] [MethodName] overloads" → fetch full page |
| Deprecated warning | "[OldType] migration v12" |
| Auth failure | "DefaultAzureCredential troubleshooting" |
| 403 Forbidden | "[ServiceName] RBAC permissions" |
Always verify when:
UploadFile vs actual Upload)CloudBlobClient vs v12 BlobServiceClient)Azure.* for .NET, azure-* for Python)Before generating code using Microsoft SDKs, verify it's correct:
microsoft_docs_search(query: "[ClassName] [MethodName] [Namespace]")microsoft_docs_fetch(url: "...")microsoft_code_sample_search(query: "[task]", language: "[lang]")For simple lookups, step 1 alone may suffice. For complex API usage, complete all three steps.
If the Learn MCP server is not available, use the mslearn CLI from the command line instead:
| 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.
