Use Foldr with Cline (MCP)
Cline is an open-source autonomous coding agent that runs as a VS Code extension, pairing with any LLM provider. Cline was one of the earliest community tools to ship robust MCP support and even includes an MCP marketplace. Foldr fits naturally alongside its file-system and browser tools — it is the "send it out to the internet" primitive Cline was missing.
Installation
Add the Foldr MCP server to Cline 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_..." },
"disabled": false,
"autoApprove": ["upload_file", "shorten_url"]
}
}
}Setup tip: Click the MCP Servers icon in the Cline sidebar → "Configure MCP Servers" and paste the config. Cline hot-reloads on save.

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