02Multipart uploads for large files
03Four file visibility levels
04File management REST API
05Find examples through document search

Use cases

01Upload ordinary files
02Handle large files in parts
03Serve files with access controls
04Find code examples for file operations

MCP support

The guide notes that bkend MCP has no dedicated storage tools. MCP clients can search storage documentation and use it to generate REST API code for file operations.

MCP Storage Workflow

bkend MCP does NOT have dedicated storage tools. Use this workflow:

Search docs: search_docs with query "file upload presigned url"
Get examples: search_docs with query "file upload code examples"
Generate code: AI generates REST API code for file operations

Searchable Storage Docs

Doc ID	Content
`7_code_examples_data`	CRUD + file upload code examples

REST Storage API

Method	Endpoint	Description
POST	/v1/files/presigned-url	Generate presigned URL
POST	/v1/files	Register metadata (complete upload)
GET	/v1/files	File list
GET	/v1/files/:fileId	File detail
PATCH	/v1/files/:fileId	Update metadata
DELETE	/v1/files/:fileId	Delete file
POST	/v1/files/:fileId/download-url	Generate download URL

Multipart Upload (Large Files)

Method	Endpoint	Description
POST	/v1/files/multipart/init	Initialize multipart upload
POST	/v1/files/multipart/presigned-url	Get part upload URL
POST	/v1/files/multipart/complete	Complete multipart upload
POST	/v1/files/multipart/abort	Abort multipart upload

Upload Flow (Single File)

1. POST /v1/files/presigned-url -> { url, fileId }
2. PUT {url} with file binary + Content-Type header
3. POST /v1/files with { fileId, filename, contentType, size, visibility }

Multipart Upload Flow (Large File)

1. POST /v1/files/multipart/init -> { uploadId }
2. POST /v1/files/multipart/presigned-url -> [{ partNumber, url }]
3. PUT each part URL with file chunk
4. POST /v1/files/multipart/complete -> { file }

Prepare azd-based Azure projects for deployment: generates azure.yaml, infrastructure (Bicep/Terraform), and Dockerfiles for the Azure Developer CLI (azd) workflow. USE ONLY when the user explicitly wants to use azd as the deployment tool, or the project already has an azure.yaml file. DO NOT USE FOR: non-azd deployments, Python App Service code-only deploys (use python-appservice-deploy), or cross-cloud migration (use azure-cloud-migrate). WHEN: prepare app for azd, create azure.yaml, set up azd infrastructure, modernize app for Azure with azd, deploy with azd, function app, timer trigger, service bus trigger, event-driven function, managed identity, generate Bicep, generate Terraform, create and deploy to Azure.
