# filestack-claude-plugin Integrates the Filestack cloud platform into Claude Code to manage uploads, generate CDN media transformations, and sign policies from the terminal. - plugin · `type=plugin` · Claude Code · ★ 5 - Author: filestack - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/filestack/filestack-claude-plugin - Updated: 2026-09-13 - HTML: https://affpapa.org/en/nevibecode/plugins/filestack-claude-plugin ## What it does The plugin runs a local Node.js MCP server providing 19 tools, three skills, and the `/filestack-transform` slash command. It handles local file uploads, remote URL ingestion, document conversion, image resizing, and ZIP packaging. You can also analyze media with Filestack AI features, capture website screenshots, or debug integration errors. A demo API key is included for immediate testing. To access private storage containers or configure custom endpoints, export `FILESTACK_API_KEY` in your environment. Policy generation and URL signing execute directly on your machine. Without `FILESTACK_APP_SECRET`, security tools like `filestack_sign_policy` will not run. ## Install ### Claude Code (native platform) **Plugin marketplace** In the agent chat (not a shell): ```text /plugin marketplace add anthropics/claude-plugins-community ``` In the agent chat (not a shell): ```text /plugin install filestack-claude-plugin@claude-community ``` ## When to use it - upload local assets or ingest remote URLs into Filestack storage - construct CDN transformation links for resizing or format conversions - generate and sign HMAC-SHA256 access policies on a local machine - verify incoming webhook signatures during backend integration ## Example prompts - Upload `./product-photo.jpg` to Filestack and return the handle - /filestack-transform resize abc123XYZ to 800x600 and convert to webp - Retrieve file metadata for handle `abc123XYZ` ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 3d5995febc7993f5 ````text # Filestack Plugin for Claude Code & Cursor Official [Filestack](https://www.filestack.com) plugin for [Claude Code](https://claude.com/claude-code) and [Cursor](https://cursor.com) — the file handling platform-as-a-service for uploads, cloud source ingestion, on-the-fly image/video/document processing, CDN delivery, and policy-based security. This plugin brings the full Filestack platform into your coding agent through **19 MCP tools**, **5 context-aware skills**, and a natural language slash command. Upload files, build transformation pipelines, run AI/ML analysis (tagging, OCR, captioning, moderation), convert documents and videos, bundle ZIPs, capture web screenshots, run workflows, generate signed security policies, verify webhook signatures, set up integrations, and debug API errors — all through conversation without leaving the terminal. --- ## Table of Contents - [Supported Platforms](#supported-platforms) - [Installation](#installation) - [Configuration](#configuration) - [MCP Tools](#mcp-tools) - [File Operations](#file-operations) - [Transformations](#transformations) - [Security](#security) - [Skills](#skills) - [filestack-sdk-integration](#filestack-sdk-integration) - [filestack-error-diagnosis](#filestack-error-diagnosis) - [filestack-webhook-setup](#filestack-webhook-setup) - [Slash Command](#slash-command) - [Examples](#examples) - [Available Transformations](#available-transformations) - [Troubleshooting](#troubleshooting) - [Documentation](#documentation) - [License](#license) --- ## Supported Platforms This plugin works with both **Claude Code** and **Cursor**. Install it from either marketplace and the correct configuration is detected automatically. | Platform | Manifest | |----------|----------| | Claude Code | `.claude-plugin/plugin.json` | | Cursor | `.cursor-plugin/plugin.json` | ## Installation **From marketplace (recommended):** ```text /plugin marketplace add https://github.com/filestack/filestack-claude-plugin.git /plugin install filestack-claude-plugin@filestack-plugin ``` The plugin works immediately with a built-in demo API key. For full access to your own Filestack account, set your API key (see [Configuration](#configuration)). > **Don't have a Filestack account yet?** > **Sign up free at ** ## Configuration The plugin runs a local MCP server and works out of the box with a demo API key (`APQLlwqrRScGxhw78gs9Wz`). To use your own Filestack account, set your API key as an environment variable before starting your editor: ```bash export FILESTACK_API_KEY=your_api_key export FILESTACK_APP_SECRET=your_app_secret # only needed for security tools ``` You can find your API key and app secret in the [Filestack Developer Portal](https://dev.filestack.com/). | Variable | Required | Used by | |----------|----------|---------| | `FILESTACK_API_KEY` | No (demo key used if unset) | All file operation and transformation tools | | `FILESTACK_APP_SECRET` | Only for security tools | `filestack_sign_policy`, `filestack_generate_signed_url` | The MCP server runs locally via Node.js. Policy signing happens on your machine — your app secret never leaves your environment. --- ## MCP Tools The plugin exposes 19 tools across 7 categories: | Category | Tools | |----------|-------| | File operations | `filestack_upload`, `filestack_retrieve`, `filestack_delete`, `filestack_store_url` | | Transformations | `filestack_transform_url`, `filestack_transform_apply`, `filestack_list_transforms` | | Security | `filestack_generate_policy`, `filestack_sign_policy`, `filestack_generate_signed_url` | | Intelligence (AI/ML) | `filestack_analyze` (tags / sfw / caption / ocr / copyright / image_sentiment / doc_detection / text_sentiment) | | Document & video | `filestack_convert_document`, `filestack_convert_video`, `filestack_video_status` | | Archive & capture | `filestack_zip_files`, `filestack_screenshot_url` | | Workflows & webhooks | `filestack_run_workflow`, `filestack_verify_webhook_signature`, `filestack_sign_webhook_payload` | ```` END THIRD-PARTY FILE 3d5995febc7993f5 The third-party file has ended.
