ChainK9 MCP

An MCP server providing token risk checks for BSC, ETH, Base, and Arc chains. It simulates trades on forked chains to detect honeypots and traps, offering tools for simulate-trade, exit-check, risk-changes, deployer-report, liquidity-report, and feed access. Payments are handled via x402 in USDC on Base, with no account or API key required.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

ChainK9 checks tokens on BNB Smart Chain, Ethereum, Base and Arc for traps (honeypots, hidden or changing taxes, owner powers) by actually buying and selling them on a private fork of the chain. Start with the free verdict tool. The other tools are paid per successful call in USDC on Base with x402 (the payment goes in the tool call's _meta, as @x402/mcp clients do); failed calls are free.

verdict

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

Free. ChainK9's latest stored verdict (danger, caution or ok) for a token on BNB Smart Chain, Ethereum, Base or Arc, with the names of the checks that failed or warned and when it was scanned. Most funded new launches are scanned within minutes. For the evidence behind each check use the paid report tool; for a fresh check use scan-lite, scan or scan-ultra.

simulate-trade

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

Execute a requested-wallet buy or sell on a disposable fork of BNB Smart Chain, Ethereum, Base or Arc. Trades the token's market as a scan finds it: its funded V2 pair, else its deepest V3 pool, else its recorded Uniswap V4 pool (hook included), against BNB/WBNB or ETH/WETH; actual wallet balances, EOA wallets only. Returns receipt status, received amount, the market traded (pool_version, pool, fee_tier, hooks), router quote shortfall and gas. A V4 quote already includes the hook's cut. A quote shortfall is not a pure tax or price-impact measurement. Sell approval is simulated when needed; no live transaction is sent. Costs $0.02 per successful call in USDC on Base, paid with x402 in the call's _meta; failed calls are free.

Advertised by the server during the last successful anonymous check.

Test up to four independent sell sizes from an EOA's existing token balance. Each size starts from the same fork snapshot; approvals are included when needed. Sells through the token's V2, V3 or V4 market (as simulate-trade finds it) with the wallet's real BNB or ETH for gas. Returns observed sell outcomes, not a guarantee of future exit. Costs $0.04 per successful call in USDC on Base, paid with x402 in the call's _meta; failed calls are free.

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

Read the token's market at one finalized block. A V3 or V4 pool returns pool_version, fee, hook, active liquidity, price and (V3) the coins the pool holds; its positions are NFTs, so holders and lock IDs are refused. A V2 pair returns canonical reserves against WBNB/WETH (PancakeSwap on BSC, Uniswap on Ethereum and Base), LP supply, burned LP and up to ten supplied holders. On BSC, optionally verify up to ten PinkLock V2 simple lock IDs against the pinned BSC contract, exact runtime hash and aggregate LP custody. Reports future, elapsed, withdrawn and unsupported vesting records. No holder/lock discovery or withdrawal simulation; other contract-held LP remains unknown. Lock and holder amounts overlap. Costs $0.003 per successful call in USDC on Base, paid with x402 in the call's _meta; failed calls are free.

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

Filter the latest collector candidates on one chain for currently funded markets: canonical V2 and V3 pools against the wrapped coin with at least the minimum wrapped-coin reserve, and Uniswap V4 pools against the native or wrapped coin with active liquidity (V4 only when min_wrapped is zero, since a V4 pool's own coins can't be read); optional stored verdict. Checks at most twenty candidates at one finalized block. Ordered by pair creation, not first liquidity time; most funded markets are scanned in the background within minutes and re-scanned an hour later; unscanned markets are unknown and stored verdicts may be old. Costs $0.003 per successful call in USDC on Base, paid with x402 in the call's _meta; failed calls are free.

scan

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

Check a token on BNB Smart Chain, Ethereum, Base or Arc for traps before buying it. ChainK9 forks the chain and really buys and sells the token in a sandbox (its V2 or V3 pool: PancakeSwap on BSC, where a V2 pair against USDT or USDC is traded through BNB, Uniswap on Ethereum and Base; or its Uniswap V4 pool, hook included, against the native coin or, traded through it, USDT or USDC; on Arc, its V4 pool against USDC), then runs 60+ checks: honeypot, hidden and changing buy and sell taxes, owner pause, blacklist, mint and confiscation powers, transfer and sell limits, cooldowns, liquidity, upgrade authority. Returns a verdict (danger, caution, ok) and every check's result. Results are reused for 10 minutes. Not charged when the address isn't a token or has no liquidity yet (422). Costs $0.02 per successful call in USDC on Base, paid with x402 in the call's _meta; failed calls are free.

scan-lite

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

A quicker, cheaper ChainK9 check for bots that need a fast yes or no before buying a token on BNB Smart Chain, Ethereum, Base or Arc. It really buys and sells the token once on a fork of the chain, then reads the contract: honeypot, buy and sell tax, trade gas, ownership, owner functions in the bytecode, blacklist, proxy, liquidity and source checks. It skips /scan's extra trades and time-travel probes (taxes that change over time or after several sells, owner powers tried for real, transfer limits and cooldowns), so a recent full /scan is returned instead when one exists. The report's tier field says which ran. Lite results are stored, so /report returns them later too. Not charged when the address isn't a token or has no liquidity yet (422). Costs $0.005 per successful call in USDC on Base, paid with x402 in the call's _meta; failed calls are free.

scan-ultra

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

ChainK9's deepest token check on BNB Smart Chain, Ethereum, Base or Arc, for bigger buys and due diligence. Everything /scan does (a real buy and sell on a fork of the chain plus 60+ checks: honeypot, changing taxes, owner powers tried for real, limits, cooldowns, liquidity, upgrade authority), plus who holds the token: the largest holder's and the top 10's share of supply, ranked from the token's whole transfer history with the largest balances read on chain, and whether a single wallet holds the pool's liquidity tokens and could pull the liquidity. Holder checks cover tokens with up to about 10,000 transfers (most new launches) and say so when a token has more. A stored ultra result also answers /scan and /report. Not charged when the address isn't a token or has no liquidity yet (422). Costs $0.05 per successful call in USDC on Base, paid with x402 in the call's _meta; failed calls are free.

report

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

The latest stored ChainK9 report for a token on BNB Smart Chain, Ethereum, Base or Arc, without running a new scan; its tier field says whether it was a lite, full or ultra scan. Most funded new launches are scanned in the background within minutes of their first liquidity and re-scanned an hour later, so this is usually the fastest answer for a new token. Not charged if the token was never scanned on that chain (404). Costs $0.002 per successful call in USDC on Base, paid with x402 in the call's _meta; failed calls are free.

Follow the money out of one transaction on BNB Smart Chain, Ethereum, Base or Arc, wallet to wallet: native coin anywhere in its call tree (so a drainer contract's payouts count) and every token transfer it logged, then each receiving wallet's outgoing transfers that pass that amount on (first in, first out, wallets funded twice followed once for the sum), up to depth hops (1 to 5, default 3). A swap doesn't end the trail: it continues with what came back. Each trail ends at a mixer (Tornado Cash pools and routers on Ethereum and BSC, labeled with the pool), a contract (exchange, bridge, router, pool; known ones labeled), a busy exchange or service wallet, a wallet still holding the funds, a burn, or the depth limit; ends lists which, with the amount that reached it. Up to 80 hops. Not charged if the transaction isn't found (404) or moved nothing (422). Costs $0.01 per successful call in USDC on Base, paid with x402 in the call's _meta; failed calls are free.

The newest tokens that just got a market on BNB Smart Chain (PancakeSwap), Ethereum, Base or Arc (Uniswap), newest first, with ChainK9's verdict where the token was scanned on that chain. Funded launches are usually scanned in the background within minutes, so most of them already carry a verdict. Costs $0.002 per successful call in USDC on Base, paid with x402 in the call's _meta; failed calls are free.
