Brain On BNB MCP

START HERE for any BSC token. Honeypot and rug-pull pre-trade check, measured not labelled: For an agent about to trade ANY token on BNB Smart Chain: the check to run before every trade, in one call and at YOUR size. Answers the two questions that matter before signing - can I get in, and can I get out again - and what the trip costs. Returns stop[] (facts that end an automated trade: the sell does not go through from a fresh address, nothing quotes, half the money is gone on an immediate round trip) and caution[] (facts to weigh, each with its figure and the line it was measured against: a transfer tax that is high, unknown or changeable by the owner; a size that moves the price more than 1%; a deeper pool elsewhere; LP that can still be withdrawn, and by whom - the deployer holding the LP is named - or that was already withdrawn; holders unknown or concentrated; the deployer or a wallet it funded selling into the pool (net of liquidity it added back), a top holder selling over a quarter of its balance, launch buyers holding over 10%; contract flags), then the figures: the token’s spot price in dollars from the pool read (token.price_usd), the best PancakeSwap route at this size, what you pay and receive, the slippage in bps this size really needs, per side, from the measured tax (a fee-on-transfer token reverts below its tax), the round trip with the transfer tax applied (measured from executed trades, or, when the pool has not traded in the window, simulated on chain at that block — the answer says which), the 1% depth in both directions, LP burned and who holds the rest, pool and token age, the swaps of the last hour and who sold in it (flow). A short answer, built from bsc_pool_scan and pancakeswap_best_route, which stay available under details for every figure behind it. A token still on its four.meme launch curve is answered from four.meme's own contract. It also reads who controls the contract on-chain (control: owner() / getOwner() and whether that owner is renounced, a plain wallet or a contract, an EIP-1967 proxy and its admin, a mint(address,uint256) function in the bytecode) and names an owner that is one wallet where the token has a tax, a mint function or a proxy. gate is the verdict in one word to branch on - stop, weigh or no_known_stop - and each stop/caution item with a figure carries it as value, line and unit. A refusal comes with a code (is_wallet, not_a_token, bad_address, bad_usd, ...) and a hint. It does not say "safe" and returns no score: it cannot see an owner who has not acted yet, and says so. No API key; pool figures are never cached, the GoPlus contract flags and holder list for up to 6 h.

Free for 1,000 scans per caller a day, then a day pass. The full honeypot / rug-pull / liquidity read behind the preflight. Measure what a trade on BNB Smart Chain would actually cost, for ANY token or pool — before placing it. Reads the pool live from the chain and returns: real cost per trade size (price impact + swap fee + transfer tax together, not the headline slippage a router shows), the USD size that moves the price 1% in each direction, the transfer tax measured from executed trades (simulated on chain at that block when the pool has not traded in the last hour, and flagged measured:false) rather than taken from a label, how much of the token's liquidity the readable pool actually holds, and whether the LP is burned or still withdrawable — plus our own sell simulation on the router from a fresh address (sellability). A token still raising on four.meme with no pool yet is measured from four.meme's own contract instead (curve: raise progress, price, buy/sell cost per size, fee). Works on PancakeSwap V2, V3 and Infinity CL (an Infinity pool is found from its key on chain and priced by PancakeSwap's own Infinity quoter, its hook included), Uniswap V2 and V3, and Biswap; a token still on four.meme's or flap.sh's launch curve is read from that curve. Read tax.measured and tax.source before using the cost columns: a tax that could not be measured comes back null with a warning, never as 0%; quotable: false with a reason is an answer, not an error. Also returned: deeperPoolElsewhere (a bigger pool for the same token than the one read), tax.simulated (an independent cross-check next to the measured tax), lp.custody (who holds the LP of a V2 pair, wallet by wallet, the deployer flagged; complete from the pair's own logs when it is under an hour old; V3 positions not read), holders (the largest wallets with exchange, lock and burn addresses named apart, or unknown: true with the reason when there is no real list yet), age (pool and token, from the first block their code existed), activity (swaps, buys vs sells, unique traders, volume and the largest sell over the window read), flow (who sold over that window: the deployer and wallets it funded, netted against liquidity they added back to the same pair, top holders selling over a quarter of their balance, and for a pool under an hour old the launch-block buyers still holding), venues[] (the scanned pool first, pools under $100 left out) and contract.properties (the GoPlus contract flags, true/false/null, with the ones it did not check named). No API key; pool figures are never cached, contract properties (from GoPlus) for up to 6 h. Free for 1,000 scans per caller and UTC day; past that it answers code free_limit, and a day pass carries on (POST https://agent.brainonbnb.com/scan-pass: 0.50 USD1, half that in $BOBAI, nothing for a wallet holding 1,000,000 $BOBAI), sent as HTTP header X-Scan-Pass.
