Use Foldr with Cursor (MCP)
Cursor is the AI-first fork of VS Code used by hundreds of thousands of engineers for paired coding with Claude and GPT-4. Cursor added first-class MCP support in its 0.45 release, exposing servers to every agent and Cmd-K command. Adding Foldr gives Cursor a place to upload generated assets (screenshots, PDFs, design exports) and turn them into shareable URLs inline.
Installation
Add the Foldr MCP server to Cursor with the snippet below. Replace fs_live_... with an API key from foldr.space/developers.
{
"mcpServers": {
"foldr": {
"url": "https://foldr.space/api/mcp",
"headers": {
"Authorization": "Bearer fs_live_..."
}
}
}
}Setup tip: Open Cursor Settings → MCP → "Add new MCP server" and paste the config, or edit ~/.cursor/mcp.json directly.

Cursor + Foldr FAQ
How do I install the Foldr MCP server in Cursor?
Open Cursor's MCP configuration (the JSON settings file) and paste the config block shown above. Set FOLDR_API_KEY to a key you create at foldr.space/api-keys. Restart Cursor if it doesn't hot-reload.
Which Foldr plan do I need to use the MCP integration with Cursor?
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 Cursor says the Foldr tool isn't available — what's wrong?
The two most common issues: (1) Cursor 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 Cursor upload files directly to Foldr, or just generate URLs?
Cursor 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 Cursor can read from disk can be uploaded.
Is the Foldr MCP integration with Cursor production-ready?
Foldr's MCP server is stable and used in production. Cursor's MCP support is currently stable and generally available. We pin to stable SDK versions and publish changelog entries for every breaking change.
