A set of instructions for answering questions about TON, a blockchain network, and GRAM, its native token. It uses a read-only wallet connection to retrieve balances, tokens, transactions, prices, NFTs, and .ton names.

Use it to inspect a TON wallet, resolve a .ton name to an address, check GRAM or token prices, view jetton and NFT holdings, and review recent transactions.

It provides a defined way to look up blockchain information without handling private keys or moving funds.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00080	$0.00482
Opus 5.5	$0.00032	$0.00193
Sonnet 5.5	$0.00016	$0.00096
Haiku 4.5	$0.00008	$0.00048

Security

Grade A, and why

ton-gram scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

TON / GRAM on-chain queries

Answer questions about The Open Network (TON) and its native token GRAM (formerly Toncoin, ticker TON → GRAM since 2026‑06‑15) using the tegro-wallet-mcp MCP server. Read-only, no keys, cannot move funds.

Prerequisite

The tegro-wallet-mcp MCP server must be connected:

claude mcp add tegro-wallet-mcp -- npx -y @tegroton/wallet-mcp

Tools

ton_get_account(address) — GRAM balance, status, wallet flag
ton_get_jettons(address, currency?) — jetton (token) balances + fiat value
ton_get_transactions(address, limit?) — recent activity (GRAM amounts, comments)
ton_get_rate(token?, currency?) — GRAM (default) or jetton price + 24h change
ton_get_jetton_info(master) — token metadata by master address
ton_get_nfts(address, limit?) — NFTs owned
ton_resolve_dns(name) — .ton name → wallet address

How to answer

A .ton name (e.g. foundation.ton) → call ton_resolve_dns first, then use the returned address.
"How much is GRAM / Toncoin / TON?" → ton_get_rate (token defaults to ton, returned as GRAM).
"What's in wallet X?" → ton_get_account + ton_get_jettons; add ton_get_nfts only if asked.
Always name the native token GRAM; the network and addresses stay TON (e.g. "TON address").
This is read-only — never offer to send, sign, or move funds.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
