Connect Claude & ChatGPT to FilePost

Ask your AI to upload a file and give you a public link, copy a file from a URL into FilePost, or find a file you uploaded last week. It can create intake links so other people can send you files, list what came in, and delete files you no longer need. Your AI gets a place to put files and hand out links.

Connect FilePost free

Free plan, no credit card. Takes about a minute.

Try asking

“Save this report as report.pdf and give me a link that expires in 7 days.”
The AI uploads the file and returns its public link. FilePost deletes it automatically after 7 days.
“Copy the image at this URL into FilePost.”
It fetches the file from the public URL and gives you a permanent link. This needs a verified FilePost account.
“Make an upload link where clients can send me up to 5 PDFs.”
It creates an intake link with a label, a file limit and allowed file types that you can share.

What your AI can do

Upload and share

Upload files from base64 data or a public URL and get a permanent public link, with optional auto-delete after a set time.

Manage files

List your files, read one file's details and link, choose whether the filename shows in the link, and delete files.

Intake links

Create links that let others upload files to you, see what came in, and deactivate a link when you are done.

“What has been uploaded through the Client documents intake link?”
It reads the intake link and lists the files sent through it.
“Delete the file I uploaded yesterday called draft.docx.”
It finds the file in your list and deletes it. The public link stops working and this cannot be undone.
“How much of my FilePost allowance have I used?”
It reads your account info and current usage.

Questions

What can the AI do in FilePost?

The AI can upload files from base64 data or from a public URL, list your files and read their details and links, change whether a filename shows in its link and delete files. It can also create, list, read and deactivate intake links and show your account usage.

Does the AI see my FilePost credentials?

No. Your FilePost API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can leave out deletes. Deleting a file or deactivating an intake link can require your approval before it runs. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own FilePost account. HeyMyApps is not affiliated with FilePost.

Are uploaded files public?

Yes. Every file uploaded to FilePost gets a public link, and anyone with the link can open it. Do not upload anything you would not share. You can set an expiry when uploading, or delete a file later, to stop the link from working.
