ChainK9 MCP server

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

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 60+ 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.

Every tool takes chain: bsc (default), eth or base.

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, 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.
