Use Foldr with ChatGPT iOS (MCP)

ChatGPT iOS is the most installed AI app on mobile. It shares Custom Connectors with the desktop client, so any MCP-compatible server set up on the web is available on your phone. Foldr on ChatGPT iOS is the fastest way to upload a camera-roll file and share a URL — no intermediate screenshots required.

Installation

Add the Foldr MCP server to ChatGPT iOS with the snippet below. Replace fs_live_... with an API key from foldr.space/developers.

chatgpt.com → Settings → Connectors → Add custom connector
Name:    Foldr
URL:     https://foldr.space/api/mcp
Auth:    Bearer  →  fs_live_...

(The connector syncs automatically to ChatGPT iOS.)

Setup tip: Custom Connectors are a Team/Business/Enterprise feature — ensure your workspace has them enabled.

ChatGPT iOS + Foldr FAQ

How do I install the Foldr MCP server in ChatGPT iOS?

Open ChatGPT iOS's MCP configuration (Settings → Connectors / Integrations) and paste the config block shown above. Set FOLDR_API_KEY to a key you create at foldr.space/api-keys. Restart ChatGPT iOS if it doesn't hot-reload.

Which Foldr plan do I need to use the MCP integration with ChatGPT iOS?

The Foldr MCP server is available on every paid plan (Pro from $5/mo and Developer tier for API-heavy usage). The free tier can generate temporary 7-day links; for permanent storage, a Pro plan or Foldr Space is required.

I set the key but ChatGPT iOS says the Foldr tool isn't available — what's wrong?

The two most common issues: (1) ChatGPT iOS wasn't restarted after editing the config — most MCP hosts need a restart to pick up new servers. (2) Your API key is missing the `mcp:invoke` scope. Regenerate a key at foldr.space/api-keys with full scope and retry.

Can ChatGPT iOS upload files directly to Foldr, or just generate URLs?

ChatGPT iOS can do both. The MCP server exposes tools for `upload_file` (takes a local path or base64 blob), `shorten_url`, and `create_bio_page`. On mobile, uploads use the device camera roll / share sheet via the remote MCP endpoint.

Is the Foldr MCP integration with ChatGPT iOS production-ready?

Foldr's MCP server is stable and used in production. ChatGPT iOS's MCP support is currently in public beta — suitable for day-to-day use. We pin to stable SDK versions and publish changelog entries for every breaking change.
