    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; actu

    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. Ret

    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 (Pancake

    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

Common questions

Is Chaink9 safe?

It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: CHAINK9_PRIVATE_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed 5 days ago, and the latest version (0.2.3) reached the registry 5 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

In the same category: World Monitor, Claude Flow, Tldraw

ChainK9 MCP server

Token risk checks for AI agents on BNB Smart Chain, Ethereum, Base and Arc.

Most token scanners read flags from someone else's API. ChainK9 does what a buyer would: it forks the chain and really buys and sells the token through its market (PancakeSwap or Uniswap V2, V3 or V4, hooks included), then runs 70+ checks. A honeypot is caught by what it does, not by what its code looks like.

Each successful call is paid automatically in USDC on Base with the x402 protocol, from a wallet you choose. There is no account and no API key, and failed calls (bad input, not a token, no liquidity, engine busy) are free.

Tools

The tool list is read live from api.chaink9.com, so new products appear without updating this package.

ToolPriceWhat it does
scan$0.02Full check of a token: honeypot, buy/sell taxes and how they change, owner pause, blacklist, mint and confiscation powers, limits, liquidity, upgrade authority. Verdict: danger, caution or ok.
scan-lite$0.005Faster check for bots (2–5 s): one real buy and sell plus the contract reads. Skips the extra trade and time-travel probes.
scan-ultra$0.05Everything in scan, plus who holds the token: top holder and top-10 share, and whether one wallet can pull the liquidity.
report$0.002The latest stored scan of a token, without a new one.
feed$0.002Tokens that just got a market, with a verdict where scanned.
simulate-trade$0.02Buy or sell for a given wallet on a fork, with its real balances.
exit-check$0.04Test up to four sell sizes from a wallet's real balance.
transaction-preview$0.02Run any transaction on a fork and see balance changes.
liquidity-report$0.003The token's pool: reserves and LP tokens (V2), or liquidity and price (V3/V4).
launch-feed$0.003New markets that are actually funded, optionally by verdict.
risk-changes$0.002What changed between a token's last two scans.
deployer-report$0.005A token's verified creator and their other known tokens.
portfolio-screen$0.005A wallet's balances of given tokens, riskiest first.
trace$0.01Follow the money out of one transaction, wallet to wallet and through swaps, up to five hops, until it rests, reaches a busy wallet such as an exchange, a mixer, or is burned.

Every tool takes chain: bsc (default), eth, base or arc. trace takes a transaction hash; the others a token or wallet address.

Setup

  1. Make a new wallet just for this and put a few dollars of USDC on Base in it. It needs no ETH: x402 payments are signatures, and the payment service pays the gas.
  2. Add the server to your MCP client with that wallet's private key.

Claude Code:

claude mcp add chaink9 -e CHAINK9_PRIVATE_KEY=0x... -- npx -y chaink9-mcp

Cursor, Claude Desktop or any client with a JSON config:

{

"mcpServers": { "chaink9": { "command": "npx", "args": ["-y", "chaink9-mcp"], "env": { "CHAINK9_PRIVATE_KEY": "0x..." } } } }

Claude Desktop can also install the .mcpb bundle from the releases with a click.

Hosted server, no install

https://api.chaink9.com/mcp serves the same tools over streamable HTTP (MCP 2025 and 2026-07-28 clients alike), plus a free verdict tool (the stored verdict and which checks flagged it). Paid tools there take the payment inside the MCP call, x402-style, so they need an x402-aware client such as @x402/mcp's createx402MCPClient. Ordinary MCP clients can connect and use verdict; to pay from those, use the package above.

Limits

VariableDefaultMeaning
CHAINK9_PRIVATE_KEY(required)Private key of the dedicated Base wallet that pays.
CHAINK9_MAX_USD_PER_CALL0.05Any single payment above this is refused.
CHAINK9_MAX_USD_PER_DAY1Stops paying once this much was spent today (UTC).

The daily total is kept in ~/.chaink9-mcp/spend.json. The wallet only ever signs payments on Base, and the key never leaves your machine.

Disclaimer

ChainK9 reports what happened when it traded the token on a private copy of its blockchain at the block shown. That is evidence, not a guarantee: a token's owner can change its rules after the scan, and traps no check tests can be missed. Nothing here is financial advice; you trade at your own risk.
