Upload a file in chunks when sandbox curl/network is blocked. PREPARATION — run this bash script first to split and hash: python3 -c " import base64, hashlib, os, json, math path = '<SANDBOX_FILE_PATH>' CHUNK = 4096 size = os.path.getsize(path) n = math.ceil(size / CHUNK) os.makedirs('/tmp/nkz', exist_ok=True) hashes = [] with open(path, 'rb') as f: for i in range(n): raw = f.read(CHUNK) h = hashlib.sha256(raw).hexdigest() b = base64.b64encode(raw).decode() open(f'/tmp/nkz/{i:04d}.b64','w').write(b) open(f'/tmp/nkz/{i:04d}.sha','w').write(h) hashes.append(h) print(json.dumps({'chunks':n,'bytes':size,'hashes':hashes})) " Then for each chunk: read the .b64 file, read the .sha file, and call this tool: cat /tmp/nkz/0000.b64 → data_b64 cat /tmp/nkz/0000.sha → sha256 nukez_upload_chunk(filename=..., data_b64=..., sha256=..., part_no=0) Set is_last=True on the final chunk. Server verifies sha256 — hash mismatch means token corruption, retry by re-reading. Always use 4KB chunks (CHUNK=4096). Do not use larger chunks. STATELESS RELAY: part_no=0 returns job_id and file_id. Pass both back on every subsequent chunk (required when each chunk is a separate MCP session).
