What is the FileStack MCP Server?
Connect your Filestack account to any AI agent to handle complex file workflows, from cloud uploads to advanced AI content analysis, through simple commands.
What you can do
- Smart Uploads — Upload files directly from any public URL to your Filestack S3 storage using
upload_from_url. - AI Intelligence — Automatically extract text from documents (
get_ocr), detect objects and features in images (get_image_tags), and check for unsafe content (get_sfw_status). - Image Transformations — Generate optimized CDN URLs for resizing, blurring, or filtering images using
generate_transform_urlwithout manual editing. - Video Processing — Initiate and monitor asynchronous video transcoding jobs (
start_video_transcode) to convert files into web-ready formats like MP4 or HLS. - Metadata Inspection — Retrieve deep technical details including dimensions, mime types, and file sizes with
get_metadata.
How it works
- Subscribe to this server
- Enter your Filestack API Key (and optional Policy/Signature for security)
- Start processing assets directly from Claude, Cursor, or any MCP client
Who is this for?
- Developers — Automate asset pipelines and generate transformation URLs directly from the code editor.
- Content Moderators — Use AI to automatically flag unsafe images or tag visual assets at scale.
- Data Engineers — Extract structured text from scanned documents and images using OCR for downstream processing.

Frequently asked questions
How can I extract text from a scanned document or image?
Use the get_ocr tool with the file handle. The AI will perform Optical Character Recognition and return the extracted text along with its coordinates.
Is there a way to check if an uploaded image contains adult or unsafe content?
Yes, the get_sfw_status tool uses Filestack Intelligence to analyze the image and return a safety score, helping you moderate content automatically.
Can I resize an image without actually downloading and re-uploading it?
Absolutely. Use generate_transform_url to create a specific CDN URL with tasks like resize=width:400. This allows the Filestack CDN to handle the transformation on the fly.
How does the Vercel AI SDK connect to MCP servers?
Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
Can I use MCP tools in Edge Functions?
Yes. The AI SDK is fully edge-compatible. MCP connections work on Vercel Edge Functions, Cloudflare Workers, and similar runtimes.
Does it support streaming tool results?
Yes. The SDK provides streaming primitives like useChat and streamText that handle tool calls and display results progressively in the UI.
createMCPClient is not a function
