Use Foldr with Dive (MCP)

Dive is an open-source desktop MCP host that works with OpenAI, Claude, Gemini, and local Ollama models through one UI. It is aimed at teams who want a provider-neutral front-end for agents. Foldr works in Dive the same way across every model.

Installation

Add the Foldr MCP server to Dive with the snippet below. Replace fs_… with an API key from foldr.space/developers/signup. Each upload costs 5¢ - top up account credits or subscribe to Pro tier to bypass per-call charges.

  "mcpServers": {
    "foldr": {
      "command": "npx",
      "args": ["-y", "@foldr/mcp-server"],
      "env": { "FOLDR_API_KEY": "fs_live_..." }
    }
  }
}

Setup tip: Dive → Settings → MCP Servers → Edit JSON. Restart Dive.

Dive + Foldr FAQ

How do I install the Foldr MCP server in Dive?

Open Dive'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/developers/signup. Restart Dive if it doesn't hot-reload.

How much does it cost to use Foldr from Dive?

Each upload costs 5¢. You can pay by topping up account credits via the `top_up_credits` MCP tool (min $5) - every upload then debits from balance. Or subscribe to Pro tier ($25/mo) and per-call charges are bypassed entirely. Tools that don't write data (list_files, mint_capability, get_usage, etc.) are free.

I set the key but Dive says the Foldr tool isn't available - what's wrong?

Three common causes: (1) Dive wasn't restarted after editing the config - most MCP hosts need a restart to pick up new servers. (2) The API key is wrong or missing - verify the env var name your client reads (e.g. FOLDR_API_KEY) matches the config snippet above. (3) Your client doesn't support the streamable-http transport - most modern clients do, but check Dive's docs for the version that added MCP support.

Can Dive upload files directly to Foldr, or just generate URLs?

Dive can do both. The MCP server exposes tools for `upload_file` (base64-encoded file content), `bulk_upload` (up to 20 files in one call), `mint_capability` (short-lived shareable links), and `create_short_url`. Any file Dive can read from disk can be uploaded.

Is the Foldr MCP integration with Dive production-ready?

Foldr's MCP server is stable and used in production - streamable-http transport at https://foldr.space/api/mcp with 23 tools. Dive's MCP support is currently in public beta - suitable for day-to-day use. Every write endpoint accepts an Idempotency-Key so retries are safe.
