Use Foldr with Continue (MCP)

Continue is the open-source AI code assistant extension for VS Code and JetBrains, used by enterprise teams that want to bring their own models. Continue added MCP support in v0.9, letting every Chat, Edit, and Agent mode reach external tools. With Foldr connected, Continue can ship generated docs and artifacts to a URL without shell-outs.

Installation

Add the Foldr MCP server to Continue 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.

      }
    ]
  }
}

Setup tip: Edit ~/.continue/config.json and restart the Continue extension. MCP tools show up in Agent mode automatically.

Continue + Foldr FAQ

How do I install the Foldr MCP server in Continue?

Open Continue'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 Continue if it doesn't hot-reload.

How much does it cost to use Foldr from Continue?

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 Continue says the Foldr tool isn't available - what's wrong?

Three common causes: (1) Continue 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 Continue's docs for the version that added MCP support.

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

Continue 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 Continue can read from disk can be uploaded.

Is the Foldr MCP integration with Continue production-ready?

Foldr's MCP server is stable and used in production - streamable-http transport at https://foldr.space/api/mcp with 23 tools. Continue'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.
