Nukez Mcp

Step 1: Get storage pricing and payment options. Returns price breakdown and every available payment method (SOL/USDC/USDT/WETH/BETA on Solana, USDC/USDT0/MON/WETH on Monad). Each option carries a `destination_kind`: 'wallet' (native SOL — send lamports to pay_to_address), 'spl_token_account' (Solana SPL tokens — pay_to_address IS already the treasury's token account; pass it DIRECTLY as the transferChecked destination, do NOT derive an ATA from it), or 'evm_address' (Monad — send native value to the address, or call transfer() on the token contract at token_address). SPL options also include a self-contained `spl_transfer` block (program_id, destination_token_account, mint, amount_raw, decimals) you can pass straight to a signer. Review payment_options, pick one, then sign+submit externally and call nukez_pay with the resulting tx_sig. Providers: gcs (default), mongodb, storj, arweave, filecoin, firestore.

Step 2: Record an externally-executed on-chain payment. The server is keyless and never signs transactions — execute the transfer yourself (Solana sendTransaction or an EVM client) and pass the resulting signature as tx_sig. Uses pay_req_id from nukez_quote (auto-resolved from state). Specify chain and pay_asset to identify the rail (e.g. chain='solana-mainnet', pay_asset='BETA'); defaults to the quote's choice. Solana SPL pre-flight: when the quote selected an SPL token (USDC/USDT/WETH/BETA), this tool fetches the tx via read-only RPC and verifies it transferred ≥ the expected amount of the expected mint to the treasury's SPL token account. A confirmed mismatch (typically: tokens sent to an ATA derived from pay_to_address) is REJECTED with a structured WRONG_DESTINATION error and the tx_sig is NOT recorded — the quote remains valid so you can re-pay correctly. Indeterminate pre-flights (RPC down, tx not yet visible) fall through to recording.

Step 3: Confirm payment settlement on the gateway and provision the storage locker. Two modes: (a) Without `envelope`: pass pay_req_id + tx_sig (auto-resolved from state). Returns the receipt_id and a hint to build a signed `locker:provision` envelope. (b) With `receipt_id` + `envelope`: forwards the signed envelope to /v1/storage/signed_provision and activates the locker. Also accepts `receipt_id` alone to rehydrate an already-provisioned locker without re-paying.

Set up Nukez storage: checks wallet, purchases storage, and provisions locker in a single call. Call with no args to run the full flow. Call with receipt_id to rehydrate an existing locker. Providers: gcs (default), mongodb, storj, arweave, filecoin, firestore. Payments: Solana (SOL, USDC, USDT, WETH, BETA) and Monad/EVM (MON, USDC, USDT0, WETH) — chain is auto-detected.

Create a file entry and get upload_url + confirm_url for direct upload. The client PUTs raw bytes directly to the upload_url (307-redirects to GCS), then calls nukez_confirm to finalize. Bytes never transit the MCP server. Use this for large files from local/external sources against Cloud Run. For small inline content (<4KB), use nukez_store with data_b64 instead. KEYLESS (hosted) SERVER: this server holds no signing key. A call without `envelope` returns action_required='sign_envelopes' with the exact spec to sign (method, path, ops, body); sign it with your wallet and re-call with envelope=<signed result>. One file per call in envelope mode.

Store files in your Nukez locker. ALWAYS BATCH: pass ALL the files you want to upload in a SINGLE call, as a list under `files`. Do NOT loop over your file list and call nukez_store once per file — that triggers one on-chain attestation per file (slow + costs SOL fees per push). One nukez_store call with N files triggers exactly ONE attestation for the whole batch. Each list item: {name, <data_source>, content_type?, expected_size_bytes?, expected_sha256?, large?}. UPLOAD PATH PRIORITY: 1. source_url — if the file is available at a public HTTPS URL, pass it and the server fetches directly (fastest, zero token cost). 2. sandbox_path — if you have compute/bash access and the file is on disk, pass the absolute path. 3. local_path — if the file exists on local disk (desktop/CLI environments). 4. data_b64 — LAST RESORT for small content only (<4KB). Sends bytes through your context window. Accepts both base64-encoded binary and plain UTF-8 text. 5. nukez_upload_chunk — if sandbox_path curl failed (HTTP 000 / network blocked), upload in 4KB chunks with sha256 verification. Run the prep script from the response, then call nukez_upload_chunk for each chunk. NEVER base64-encode files >4KB in one call. Upload path is auto-selected based on size and runtime environment. HARD SIZE LIMITS per path: the sandbox curl proxies through the gateway and is capped at 32 MiB (the platform rejects larger request bodies); the chunked ingest pipeline caps at 20 MiB per file. LARGE FILES (>= 32 MiB, any size up to terabytes): pass expected_size_bytes (and ideally the file's expected_sha256) with sandbox_path, or set large=true — the response then returns a resumable direct-to-provider upload session (action_required='execute_upload') with a session-open command and a stdlib-only transfer script that uploads in 8 MiB chunks and resumes after interruptions. Bytes go straight to the storage provider, so the sandbox needs outbound access to the session URI's host. After the transfer, co

Confirm a file upload after sandbox curl completes. Call this after executing the curl command returned by nukez_store in sandbox mode. The server computes SHA-256 and records the hash. Requires a payer-signed locker:write envelope: signer-mode deployments sign automatically via the SDK; keyless clients first call without envelope to receive the exact envelope spec to sign, then re-call with envelope=<signed result> (the batch spec returned by nukez_store is also accepted here). LARGE FILES: pass use_job=true after a resumable upload — the synchronous confirm streams the whole stored object on the request path, so large objects confirm through the gateway's asynchronous finalize job instead. Signer mode creates and polls the job automatically; keyless mode signs the job creation spec first, then signs the returned poll spec (fresh nonce each time, re-calling with job_id) until job_status is terminal (complete, partial, or failed).

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).

List files or download content from your Nukez locker. Call with no filenames to list all files. Call with filenames=['file.txt'] to download specific files. KEYLESS (hosted) SERVER: a call without `envelope` returns action_required='sign_envelopes' with the exact list spec to sign (locker:list, plus locker:read when downloading); sign it with your wallet and re-call with the same arguments plus envelope=<signed result>.

Fast structural verification of locker state. Returns merkle root, attestation status, and optional per-file proof. Pass memory_key to verify a specific memory record by key. Cheap: reads the persisted attestation; latency is independent of locker size (~sub-second typical). With push=True, also triggers a fresh on-chain attestation: the gateway enqueues the same background job the async path uses (its Cloud Tasks worker performs the single on-chain push) and polls server-side, returning the settled attestation — or a 202-style accepted response pointing at the verify endpoint if its 90-second poll ceiling expires first. DO NOT call repeatedly after every store/delete just to keep the attestation current — the gateway already runs auto-reattest after every file mutation, gated to skip when the manifest is unchanged since the last attestation, so manual push calls are normally unnecessary. Use push=True only when you explicitly need the on-chain anchor right now and inline. For byte-level proof that storage bytes still match the recorded hashes (re-downloads everything), use nukez_recompute_verify instead.

Byte-level integrity proof: re-downloads every file from storage, recomputes content hashes, rebuilds the merkle tree, and compares the result against the persisted attestation. Returns match=True when storage bytes still match the recorded hashes, match=False when they have drifted. Cost: scales with total locker bytes (re-downloads everything). Slower than nukez_verify — reach for this only on audits, post-migration sanity checks, or when you suspect drift between storage and the persisted manifest. For routine integrity checks, nukez_verify is the right tool (sub-second, structural). Requires payer authorization (a signed locker:read envelope): signer-mode deployments sign automatically via the SDK; keyless deployments get action_required='sign_envelopes' with the exact envelope spec, then re-call with envelope=<signed result>.

Check wallet balance, locker state, and lifecycle stage. Works at any stage — no active locker required.

Delete files from your Nukez locker. WARNING: permanent and irreversible. Invalidates existing attestation. KEYLESS (hosted) SERVER: a call without `envelope` returns action_required='sign_envelopes' with the exact delete spec to sign (locker:write, bound to one file's path); sign it with your wallet and re-call with filenames=[that file] plus envelope=<signed result>. One file per call in envelope mode.

Store a structured memory record in your Nukez locker. Memories are indexed for fast search via nukez_recall. Use namespaces to organize (e.g., 'config', 'context', 'decisions'). Requires: key, content, summary. ENVELOPE: pass a list of 2 envelopes (each with unique nonce, POST path, ops=locker:write) — one for the record file, one for the index.

Search and retrieve memory records from your Nukez locker. Two modes: exact key lookup (pass key) returns full content + proof, or search (pass namespace/tags/query/prefix) returns matching index entries. ENVELOPE: none needed — both index and record are read via the public receipt-proxy URL. Just pass receipt_id.
