Use Foldr with LibreChat (MCP)
LibreChat is a mature open-source ChatGPT alternative with plugin support, multi-user auth, and a growing MCP implementation. It is the most common self-hosted chat stack for teams that want centralized billing plus BYO-model. Foldr fits in alongside its other tool plugins for quick file sharing from chat.

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