Use Foldr with ChatGPT Desktop (MCP)

ChatGPT Desktop is OpenAI's native app for macOS and Windows, now with support for "Custom Connectors" — OpenAI's MCP-compatible tool protocol for Team and Enterprise users. Connecting Foldr puts the full upload, short-link, and bio-page surface inside ChatGPT without a browser round-trip.

ChatGPT Desktop + Foldr FAQ

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

Open ChatGPT Desktop'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 Desktop if it doesn't hot-reload.

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

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 Desktop says the Foldr tool isn't available — what's wrong?

The two most common issues: (1) ChatGPT Desktop 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 Desktop upload files directly to Foldr, or just generate URLs?

ChatGPT Desktop can do both. The MCP server exposes tools for `upload_file` (takes a local path or base64 blob), `shorten_url`, and `create_bio_page`. Any file ChatGPT Desktop can read from disk can be uploaded.

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

Foldr's MCP server is stable and used in production. ChatGPT Desktop'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.
