Overview

chaink9 MCP server evaluates tokens by trading them on private blockchain forks before returning risk results. It supports BNB Smart Chain, Ethereum, Base, and Arc, with tools for scans, stored verdicts, simulated trades, liquidity, portfolios, deployers, launches, and transaction tracing. Paid calls use USDC on Base through x402, while the free verdict tool reads the latest stored result. Reach for chaink9 when an agent needs behavioral token checks or on-chain investigation rather than contract flags alone.

Use cases

  • Screen a token before buying it
  • Simulate a wallet exit on a fork
  • Compare a token’s latest risk scans
  • Inspect liquidity and deployer history
  • Trace funds from a suspicious transaction

Key features

  • Fork-based buy and sell risk checks
  • Support for BNB Smart Chain, Ethereum, Base, and Arc
  • Lite, full, and ultra scan tiers
  • Simulated trades and transaction previews
  • Liquidity, portfolio, deployer, and launch analysis
  • x402 USDC payments with spending limits

How Chaink9 works

What chaink9 MCP server does

chaink9 MCP server gives agents tools for token-risk analysis and on-chain investigation across BNB Smart Chain, Ethereum, Base, and Arc. Its distinguishing approach is behavioral: full scans execute a real buy and sell on a disposable fork through the token’s available V2, V3, or V4 market, including supported hooks, then run more than 60 checks.

The scan family covers honeypots, changing buy and sell taxes, owner controls, blacklists, minting and confiscation powers, trading limits, cooldowns, liquidity, and upgrade authority. scan-lite performs a faster, narrower check, while scan-ultra adds holder concentration and liquidity-token custody analysis. Stored results can be read with report or the free verdict tool.

How it works

Most paid calls are charged in USDC on Base using x402. The local server signs payments from a dedicated wallet; the wallet only signs Base payments, and its private key remains on the machine. Failed calls, invalid inputs, missing liquidity, and similar unsuccessful requests are free. Per-call and daily spending limits can prevent unexpected usage.

The server also exposes tools for simulated buys and sells, sell-size testing, arbitrary transaction previews, pool inspection, launch discovery, scan comparisons, deployer reports, portfolio screening, and transaction tracing. Fork-based execution does not broadcast transactions to the live chain. Results describe observed behavior at the relevant block and should not be treated as a guarantee of future trading outcomes.

Setup and configuration

Create a separate wallet, fund it with USDC on Base, and add the package to an MCP client with its private key:

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

JSON-based clients can launch npx -y chaink9-mcp and provide CHAINK9_PRIVATE_KEY in the server environment. CHAINK9_MAX_USD_PER_CALL defaults to 0.05, and CHAINK9_MAX_USD_PER_DAY defaults to 1; daily spending is recorded in ~/.chaink9-mcp/spend.json.

A hosted streamable-HTTP endpoint is also available at https://api.chaink9.com/mcp. It provides the same tools and a free verdict operation. Paid hosted calls require an x402-aware MCP client, such as the client created by @x402/mcp.

Tools and capabilities

  • Run full, lite, or ultra token scans and retrieve stored reports or verdicts.
  • Simulate buys, sells, and up to four independent exit sizes using a wallet’s forked balances.
  • Preview an EOA transaction and inspect native-coin and selected ERC-20 balance changes.
  • Examine V2 reserves and LP information, or V3/V4 liquidity and pricing.
  • Find newly funded markets, compare the latest two scans, and inspect known deployer activity.
  • Screen supplied wallet holdings and trace native or token funds through transaction call trees.

Each tool accepts a chain selection, with BNB Smart Chain as the default. Paid prices vary by operation, from the low-cost stored-report and feed tools to the deeper ultra scan and exit-check.

Limitations and notes

Scan results reflect execution on a private fork at a stated block. Owners may change token behavior afterward, and untested traps can remain. Portfolio screening reads only supplied token addresses and does not discover all wallet assets or prove wallet-specific sellability. Deployer reports cover verified creation transactions and known stored deployments, not every deployment or launchpad path.

Liquidity reporting differs by pool type: V2 data includes reserves and selected LP-holder information, while V3 and V4 data focuses on active liquidity and price. Holder and lock discovery is limited, and some LP custody remains unknown. Transaction tracing follows supported transfers to a bounded depth and can end at contracts, services, mixers, burns, wallets, or the depth limit.

Frequently Asked Questions about Chaink9

chaink9 is an MCP server that connects AI agents to token-risk and on-chain analysis tools for BNB Smart Chain, Ethereum, Base, and Arc. Its main tools scan tokens on disposable forks, retrieve stored verdicts, simulate trades, inspect liquidity, screen portfolios, report deployers, and trace funds. Paid calls use USDC on Base through x402.

Install it by launching `npx -y chaink9-mcp` from your MCP client and setting `CHAINK9_PRIVATE_KEY` to a dedicated wallet key. Claude Code supports `claude mcp add`; JSON-based clients can add the command and environment variable directly. The wallet needs USDC on Base for paid calls.

chaink9 pays for successful paid calls in USDC on Base using x402. The local package signs payments with the configured wallet, while the hosted endpoint expects an x402-aware MCP client for paid operations. Failed calls are free, and per-call and daily limits can cap spending.

Yes, chaink9 simulates sells on a disposable fork and does not send a live transaction. `simulate-trade` tests a requested buy or sell, while `exit-check` tests up to four sell sizes from an EOA’s existing token balance. Results show observed outcomes rather than guaranteeing future execution.

Yes, chaink9 works with Cursor through its standard MCP JSON configuration. Add `npx -y chaink9-mcp` as the server command and provide `CHAINK9_PRIVATE_KEY` in the environment. Cursor can use the local tools; hosted paid calls require an x402-aware client.
