Python CLI

The published Python package name is okfile.

Install the latest release from PyPI:

py -3 -m pip install okfile
okfile --version

Install a pinned version when you need reproducible environments:

py -3 -m pip install okfile==1.4.1

Upgrade to the latest release:

py -3 -m pip install --upgrade okfile

Fallback wheel install:

py -3 -m pip install "https://www.okfile.com/downloads/okfile-1.4.1-py3-none-any.whl"

If okfile is not on PATH yet, use one of these repo-local fallbacks first:

py -3 -m pip install -e .
okfile --version

py -3 -m okfile_cli --version
py -3 -m okfile_cli publish ./my-site/

Do not use py -m okfile. The published package exposes the okfile console command, while the module entrypoint is okfile_cli.

okfile config --stream-account-id <account_id> --stream-token <token>

Help examples:

okfile upload --help
okfile publish --help
okfile status --help

Notes:

• okfile upload defaults to --multipart-concurrency 3 for multipart uploads
• larger values can improve throughput for bigger files, but small files may not benefit
• okfile upload and okfile publish now retry failed file uploads by default with --retries 3 --retry-delay 2
• retry delay uses exponential backoff per file, so later retries wait longer than earlier ones
• okfile publish continues uploading other files after an individual file failure and reports a failed-file summary at the end
• okfile publish writes a local resume file by default at <site>/.okfile-publish-state.json and reuses already uploaded files on the next run when size and mtime still match
• the publish state file is deleted automatically after a fully successful site publish
• use --fail-fast when you want publish to stop immediately on the first file failure instead of collecting a failure summary
• okfile upload --stream sends video files to Cloudflare Stream with the tus resumable upload protocol; without Cloudflare credentials it uses OkFile hosted transcoding automatically
• --stream requires a Cloudflare account ID and API token with Stream Write; use command flags, okfile config, or CLOUDFLARE_ACCOUNT_ID plus CLOUDFLARE_STREAM_API_TOKEN
• okfile status --stream <video_uid> queries Cloudflare Stream video status and playback URLs
• --max-downloads only applies to OkFile file storage and cannot be combined with --stream
• --expires-at maps to Cloudflare Stream scheduled deletion when --stream is used

MCP Server

@okfilecom/okfile-mcp is a Model Context Protocol server (stdio, Node 18+) exposing OkFile as agent tools: okfile_upload_file, okfile_publish_site, okfile_upload_video_stream, okfile_get_status, okfile_get_limits. Register it with one command in Claude Code (claude mcp add okfile -- npx -y @okfilecom/okfile-mcp), Claude Desktop, or Cursor; optional env vars OKFILE_API_KEY, OKFILE_ORIGIN, and OKFILE_MCP_ROOT (restricts which local paths may be published). The source lives in mcp-server/; a self-contained build is served at https://www.okfile.com/okfile-mcp.mjs (node okfile-mcp.mjs).

What It Does

OkFile is designed for Agents, scripts, and lightweight manual upload use cases.

It supports:

• anonymous uploads
• authenticated uploads with user API keys
• video-to-streaming-media transcoding via hosted Cloudflare Stream (okfile upload video.mp4 --stream or POST /api/stream/prepare), returning watch/HLS/DASH playback URLs with no Cloudflare account required
• direct file URLs for download or embedding
• preview/playback URLs for image, video, and PDF
• anonymous single-file uploads up to 1GB
• API Key uploads up to 1TB per file
• temporary retention for anonymous uploads, with current default expiry at 24 hours
• multipart upload for larger authenticated files
• phase-1 site directory upload with nested subdirectories and per-site subdomain publish URLs
• automatic shared top-level directory stripping for folder-based site uploads
• directory listing fallback when a published site does not contain root index.html
• retrying only missing parts after incomplete multipart uploads
• email magic-link login and account management
• localized home, upload, and account pages

Main User Flows

1. Anonymous Publish

1. POST /api/upload/prepare
2. PUT uploadUrl or each parts[].uploadUrl
3. POST /api/upload/complete
4. return url and optionally playUrl
5. current single-file limit is 1GB, and uploaded files expire after 24 hours

2. API Key Publish

1. request a magic link and log in
2. create an API key in /account
3. call POST /api/upload/prepare with X-API-Key header
4. upload file data to signed URLs
5. call POST /api/upload/complete
6. current single-file limit is 1TB when a valid API key is used

3. Manual Upload

Users can also use:

• /zh/upload/
• /en/upload/

This path is kept as a fallback entry, while API integration remains the recommended flow.

4. Site Directory Publish

1. select a whole folder in /zh/upload/ or /en/upload/
2. the uploader preserves nested relative paths
3. if every file sits under one shared top-level folder, that folder is stripped and treated as the site root
4. if the site contains root index.html, / renders that page
5. if root index.html does not exist, / renders a directory listing with file name, size, and upload time
6. image and video entries open inline, while other files use download links

Architecture

Runtime

• Cloudflare Pages Functions for routing and API handling
• Cloudflare Worker route for *.ok26.org/* site subdomains
• Cloudflare R2 for file storage
• Cloudflare D1 for auth and API key metadata
• Resend for email magic links

Frontend

• static index.html for homepage
• static upload.html for manual upload
• server-side localization and SEO injection in worker-app.js

Backend Responsibilities

• issue presigned R2 upload URLs
• complete multipart uploads
• activate public file routes
• resolve published site subdomains from request Host
• manage sessions, magic links, and API keys
• enforce anonymous and per-key quota limits

Core Routes

Pages

• /zh/ and /en/: localized home pages
• /zh/upload/ and /en/upload/: manual upload pages
• /account: redirects to localized account page
• /zh/account/ and /en/account/: localized account pages
• /admin: admin console

Upload APIs

• POST /api/upload/prepare
• POST /api/upload/complete
• GET /api/upload/status/{id}
• POST /api/stream/prepare and GET /api/stream/status/{uid} for hosted video-to-streaming transcoding
• authenticated automation should send X-API-Key: okf_...

Authenticated prepare example:

curl -X POST "https://www.okfile.com/api/upload/prepare" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: okf_..." \
  --data '{"filename":"photo.jpg","size":12345,"contentType":"image/jpeg"}'

Auth APIs

• POST /api/auth/request-link
• GET /auth/verify?token=...
• GET /api/account/me
• POST /api/account/api-keys

File URLs

• /i/{id}: direct file URL
• /i/{id}?play=1: preview/playback page
• /d/{id}: controlled download route

Site URLs

• https://{subdomain}.ok26.org/: site root or directory listing
• https://{subdomain}.ok26.org/path/to/file: published site asset or document
• https://{subdomain}.ok26.org/path/to/file?download=1: force download for a site file

Local Development

Install dependencies:

npm install

Run local development:

npx wrangler pages dev .

Deploy to Cloudflare Pages:

npx wrangler pages deploy . --project-name okfile --branch main

CI/CD

.github/workflows/ci.yml runs on every push and pull request:

• test: Python CLI unit tests (tests/) plus esbuild bundle checks for the main worker and the admin worker
• deploy (push to main only): deploys all three targets from the same commit — the Pages project (www.okfile.com), the sites worker (*.ok26.org), and the admin worker (admin.okfile.com) — then runs a post-deploy smoke check

Required repository secrets (Settings → Secrets and variables → Actions):

• CLOUDFLARE_API_TOKEN: token with Pages Edit + Workers Scripts Edit + D1 Edit for the account
• CLOUDFLARE_ACCOUNT_ID: the Cloudflare account id

Deploying all three targets together prevents the Pages project and the classic workers (which share worker-app.js) from drifting apart.

Configuration

Store secrets in Cloudflare, not in the repository.

Secrets

• R2_ACCESS_KEY_ID
• R2_SECRET_ACCESS_KEY
• RESEND_API_KEY

Plain-Text Vars

• R2_ACCOUNT_ID
• RESEND_FROM_EMAIL
• ADMIN_EMAILS

Database

The D1 schema is defined in schema.sql and includes:

• users
• magic_links
• sessions
• api_keys
• api_key_usage_windows

Upload Notes

See these repo docs for integration details:

• SKILL.md
• SITE_UPLOAD_DESIGN.md
• .trae/skills/okfile/SKILL.md
• okfile-upload-pitfalls.md

The pitfalls doc includes practical notes such as:

• Cloudflare requiring a normal User-Agent for some requests
• explicit Content-Length on R2 PUT
• multipart retry strategy
• large-file client recommendations on Windows

For site publishing:

• use root index.html when you want the subdomain root to render a page
• if you upload a single wrapper folder such as my-site/..., OkFile strips my-site/ automatically
• if no root index.html exists, users land on a browsable directory listing instead of downloading an arbitrary file
