Use Foldr with Windsurf (MCP)
Windsurf (from Codeium) is an agentic IDE that popularised "Cascade" — long-running AI workflows that can read, edit and ship code with minimal supervision. MCP servers plug directly into Cascade as external tools. With Foldr connected, Cascade can upload build artifacts or design references and return a short URL you can drop in a PR description.
Installation
Add the Foldr MCP server to Windsurf with the snippet below. Replace fs_live_... with an API key from foldr.space/developers.
{
"mcpServers": {
"foldr": {
"command": "npx",
"args": ["-y", "@foldr/mcp-server"],
"env": { "FOLDR_API_KEY": "fs_live_..." }
}
}
}Setup tip: In Windsurf, open Settings → Advanced → Model Context Protocol → Edit mcp_config.json. Restart Windsurf after saving.

Windsurf + Foldr FAQ
How do I install the Foldr MCP server in Windsurf?
Open Windsurf'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 Windsurf if it doesn't hot-reload.
Which Foldr plan do I need to use the MCP integration with Windsurf?
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 Windsurf says the Foldr tool isn't available — what's wrong?
The two most common issues: (1) Windsurf 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 Windsurf upload files directly to Foldr, or just generate URLs?
Windsurf 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 Windsurf can read from disk can be uploaded.
Is the Foldr MCP integration with Windsurf production-ready?
Foldr's MCP server is stable and used in production. Windsurf's MCP support is currently stable and generally available. We pin to stable SDK versions and publish changelog entries for every breaking change.
