Upload and Download Files with AI Agents

Use MCP tools to upload code, datasets, and configs to GPU instances, and download results — all through conversation.

Transfer files to and from GPU instances without manual SCP commands. Your AI agent handles uploads, downloads, and file verification.

”Upload my training script and config to the training instance.”

The agent transfers files directly:

1. list_instances — finds the target instance
2. file_upload — uploads train.py to /workspace/train.py
3. file_upload — uploads config.yaml to /workspace/config.yaml
4. ssh_execute — runs ls -lh /workspace/ to confirm

Uploaded 2 files to training-run:

File	Size	Remote Path
train.py	3.8 KB	/workspace/train.py
config.yaml	512 B	/workspace/config.yaml

Both files verified on the instance.

”Download the trained model weights and the training log.”

The agent retrieves files from the instance:

1. ssh_execute — runs ls -lh /workspace/output/ to see what’s there
2. file_download — downloads /workspace/output/model.safetensors
3. file_download — downloads /workspace/output/training.log

Files on the instance:

-rw-r--r-- 1 root root 1.2G model.safetensors
-rw-r--r-- 1 root root  48K training.log
-rw-r--r-- 1 root root 2.1K config.json

Downloaded model.safetensors (1.2 GB) and training.log (48 KB).

File upload and download have a 10MB limit per transfer. For larger files, use ssh_execute with wget or curl to transfer directly between instances or from external URLs.

---

”Upload a requirements.txt and install everything on my dev-box.”

The agent combines file transfer with command execution:

1. file_upload — uploads requirements.txt to /root/requirements.txt
2. ssh_execute — runs pip install -r /root/requirements.txt
3. ssh_execute — runs pip list | wc -l to confirm packages installed

Uploaded requirements.txt (28 packages) to dev-box.

Installation output:

Successfully installed torch-2.4.0 transformers-4.44.0 ...

28 packages installed. Environment is ready.
