Use Foldr with Perplexity Desktop (MCP)
Perplexity Desktop is the dedicated macOS and Windows client for the Perplexity answer engine. Perplexity added "Connectors" in 2026 using an MCP-compatible surface so third-party tools can feed into research threads. Foldr lets you pull files hosted on foldr.space into a Perplexity thread or publish a Perplexity answer snapshot as a short URL.
Installation
Add the Foldr MCP server to Perplexity Desktop with the snippet below. Replace fs_live_... with an API key from foldr.space/developers.
Perplexity Desktop → Settings → Connectors → + New Name: Foldr URL: https://foldr.space/api/mcp Auth: API Key → fs_live_...
Setup tip: Requires Perplexity Pro or Enterprise. Beta — feature set evolving quickly.

Perplexity Desktop + Foldr FAQ
How do I install the Foldr MCP server in Perplexity Desktop?
Open Perplexity 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 Perplexity Desktop if it doesn't hot-reload.
Which Foldr plan do I need to use the MCP integration with Perplexity 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 Perplexity Desktop says the Foldr tool isn't available — what's wrong?
The two most common issues: (1) Perplexity 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 Perplexity Desktop upload files directly to Foldr, or just generate URLs?
Perplexity 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 Perplexity Desktop can read from disk can be uploaded.
Is the Foldr MCP integration with Perplexity Desktop production-ready?
Foldr's MCP server is stable and used in production. Perplexity 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.
