TRUSTED BY TEAMS AT

The word teachable is written in all lowercase, sans-serif letters with a colon between teach and able, in a light purple color on a light background.

Plain English. Production Output.

Upload files, build image pipelines, run OCR, transcode video, and sign security policies. Your agent handles the Filestack API calls.

See all examples →

# Upload a file
› Upload ./hero-banner.jpg to Filestack
→ { handle: "abc123XYZ",
     url: "https://cdn.filestackcontent.com/abc123XYZ" }

# Build a transformation pipeline
› Crop to face, resize 400×400, output webp
→ cdn.filestackcontent.com/crop_faces/resize=400,400/output=webp/abc123XYZ

# Generate a signed URL
› Give me a read-only signed URL, valid 2 hours
→ cdn.filestackcontent.com/abc123XYZ?policy=eyJ...&signature=a1b2...

# Use the slash command
› /filestack-transform abc123XYZ rotate 90 and monochrome
→ cdn.filestackcontent.com/rotate=deg:90/monochrome/abc123XYZ

What It Does

The Full Filestack Platform, One Conversation Away

Seven capability categories, wired into your agent from day one.

📤

File Operations

Upload local files, ingest remote URLs server-side, retrieve metadata, or delete stored files. CDN-ready handles back instantly.

🖼️

Image Transformations

Resize, crop, rotate, enhance, detect faces, watermark, convert formats. Build chained transformation URLs or persist the output as a new handle.

🔐

Security & Signed URLs

Generate scoped policies, sign them with HMAC-SHA256, and produce time-limited CDN URLs. Your app secret stays on your machine.

🧠

Intelligence (AI/ML)

Auto-tagging, NSFW detection, image captioning, OCR, copyright checks, sentiment analysis, and mobile document detection — one tool, eight tasks.

🎞️

Document & Video

Convert between DOC, DOCX, PDF, PPT, images, and more. Transcode video to HLS, DASH, MP4, or WebM with Telestream-backed async jobs.

📦

Archive & Capture

Bundle up to 100 handles into a single ZIP via CDN URL, or capture screenshots of any web page on desktop or mobile viewports.

🔀

Workflows & Webhooks

Run saved Filestack Workflows for multi-step pipelines, virus scanning, and video intelligence. Sign or verify webhook signatures locally with HMAC-SHA256.

✨

Skills & Slash Command

Five context-aware skills auto-activate on Filestack imports, errors, and webhook patterns. Plus /filestack-transform turns English into CDN URLs.

Running in Three Steps

Install the plugin, set your API key, and start using Filestack from Claude Code or Cursor. Works out of the box with a built-in demo key.

1Install from Marketplace

Add the plugin from the marketplace — the manifest auto-detects Claude Code vs. Cursor.

CLAUDE CODE

# Add plugin from marketplace
› /plugin marketplace add https://github.com/filestack/filestack-claude-plugin.git

# Install the plugin
› /plugin install filestack-claude-plugin@filestack-plugin

2Set your API key

Export your Filestack credentials before starting your editor. Find them in the Filestack Developer Portal — or skip this step to use the built-in demo key.

BASH

# Set Filestack environment variables
export FILESTACK_API_KEY=your_api_key
export FILESTACK_APP_SECRET=your_app_secret # for security tools

3Start a conversation

Open your agent and start asking.

CLAUDE CODE

Upload ./my-image.jpg to Filestack and give me a signed read URL valid for 1 hour

Skills

Five Skills. Expert Knowledge, Built In.

Skills activate on their own when your agent detects Filestack patterns — imports, error payloads, webhook headers, AI/ML tasks, or workflow design. Context-aware help, every time.

`filestack-sdk-integration`

Activates on filestack-js imports, picker config, upload calls

SDK initialization for JS/TS and Python
Picker widget configuration and cloud sources
React and Next.js patterns
Common mistakes: wrong API key scope, missing CORS whitelist

`filestack-error-diagnosis`

Activates on HTTP 401/403/404/429 errors and Filestack error payloads

HTTP error reference with likely causes and fixes
Security policy breakdown: expired, wrong scope, bad signature
Step-by-step diagnosis checklist
Rate limit detection and remediation

`filestack-webhook-setup`

Activates on FS-Signature, FS-Timestamp, webhook event types

Complete webhook event type reference
HMAC-SHA256 verification in Node.js, Python, Go
Production patterns: immediate 200 ACK, idempotency
Retry behavior: 5 retries with exponential backoff

Start using Filestack in Claude Code

Install in under a minute. Just your API key and a conversation.
