microsoft-code-reference
Look up Microsoft API references, find working code samples, and verify SDK code is correct. Use when working with Azure SDKs, .NET libraries, or Microsoft APIs—to find the right method, check parameters, get working examples, or troubleshoot errors. Catches hallucinated methods, wrong signatures, and deprecated patterns by querying official docs.
摘要
- 用途
- 依据官方文档与可运作的代码范例,确认 Microsoft API 与 SDK 的用法。
- 使用时机
- 需要确认 API 是否存在、方法签章、套件或版本相符的用法,或排查 SDK 错误时使用。
- 输出结果
- 提供相关的 Microsoft 参考资料与代码范例,协助正确实作。

822d040 Add Learn CLI option to microsoft-docs skills (#1003) 添加 mslearn CLI 作为 Microsoft Learn MCP 的替代方案,并提供运行与安装范例,以及 MCP 工具与 CLI 指令的对照。 a3035a6 Add Microsoft Code Reference and Microsoft Docs skills with detailed usage instructions 添加 Microsoft Code Reference 技能,提供使用 MCP 寻找代码范例、查找 API 详情、排查错误及验证 SDK 代码的指引。 npx skills add "lettucebo/Skills#v2.2.0@microsoft-code-reference" --full-depth ⚠ v2.2.0 发布后即可使用
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.
Error Troubleshooting
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" |
When to Verify
Always verify when:
- Method name seems "too convenient" (
UploadFilevs actualUpload) - Mixing SDK versions (v11
CloudBlobClientvs v12BlobServiceClient) - 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.
