Use Foldr with LM Studio (MCP)
LM Studio is the most popular desktop app for running local LLMs (Llama, Mistral, Qwen, DeepSeek) with an OpenAI-compatible API. LM Studio 0.3.x added MCP tool-calling, letting local models reach the same tools cloud models use. Foldr lets a fully local model still hand out a public URL for any file it produced.
Installation
Add the Foldr MCP server to LM Studio with the snippet below. Replace fs_live_... with an API key from foldr.space/developers.
{
"mcp": {
"servers": {
"foldr": {
"command": "npx",
"args": ["-y", "@foldr/mcp-server"],
"env": { "FOLDR_API_KEY": "fs_live_..." }
}
}
}
}Setup tip: LM Studio → App Settings → Integrations → Model Context Protocol. Works best with tool-calling-capable models.

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