CVE-2022-29244high · fixedCVSS 7.5

Packing does not respect root-level ignore files in workspaces

### Impact `npm pack` ignores root-level `.gitignore` & `.npmignore` file exclusion directives when run in a workspace or with a workspace flag (ie. `--workspaces`, `--workspace=<name>`). Anyone who has run `npm pack` or `npm publish` with workspaces, as of [v7.9.0](https://github.com/npm/cli/releases/tag/v7.9.0) & [v7.13.0](https://github.com/npm/cli/releases/tag/v7.13.0) respectively, may be affected and have published files into the npm registry they did not intend to include. ### Patch - Up

CVE-2018-7408high · fixedCVSS 7.8

Incorrect Permission Assignment for Critical Resource in NPM

An issue was discovered in an npm 5.7.0 2018-02-21 pre-release (marked as "next: 5.7.0" and therefore automatically installed by an "npm upgrade -g npm" command, and also announced in the vendor's blog without mention of pre-release status). It might allow local users to bypass intended filesystem access restrictions because ownerships of /etc and /usr directories are being changed unexpectedly, related to a "correctMkdir" issue.

CVE-2013-4116info · fixed

Local Privilege Escalation in npm

Affected versions of `npm` use predictable temporary file names during archive unpacking. If an attacker can create a symbolic link at the location of one of these temporary file names, the attacker can arbitrarily write to any file that the user which owns the `npm` process has permission to write to, potentially resulting in local privilege escalation. ## Recommendation Update to version 1.3.3 or later.

npm CLI exposing sensitive information through logs

Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through log files. The CLI supports URLs like `<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>`. The password value is not redacted and is printed to stdout and also to any generated log files.

npm Vulnerable to Global node_modules Binary Overwrite

Versions of the npm CLI prior to 6.13.4 are vulnerable to a Global node_modules Binary Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a `serve` binary, any subsequent installs of packages that also create a `serve` binary would overwrite the first binary. This will not overwrite system binaries but only binaries put into the global node_modules directory. This b

README

chainanalyzer-mcp

MCP Server for ChainAnalyzer — multi-chain blockchain AML risk analysis for AI agents.

Scan any address across 8 chains live for self-serve — Bitcoin, Ethereum, Polygon, Base, Arbitrum, Optimism, Avalanche, Solana — plus BNB Smart Chain on Enterprise rollout (paid Etherscan tier required, available via API key only). 76+ detection rules across 9 chains, ML anomaly scoring, and Neo4j graph analysis.

Tools

Tool	Description	Price
`check_address_risk`	AML risk score for any blockchain address	$1.00
`sanctions_check`	OFAC / FATF / JFSA sanctions screening	$0.50
`trace_transaction`	Transaction flow tracing with ML anomaly detection	$3.00
`detect_coinjoin`	CoinJoin / mixing pattern detection (Bitcoin)	$1.00
`cluster_wallet`	Wallet clustering via Neo4j graph analysis	$2.50
`batch_screening`	Batch AML screening (up to 50 addresses)	$5.00

Quick Start

Claude Desktop / Claude Code

Add to your MCP configuration:

{
  "mcpServers": {
    "chainanalyzer-aml": {
      "command": "npx",
      "args": ["-y", "chainanalyzer-mcp"],
      "env": {
        "CHAINANALYZER_API_KEY": "tfk_your_api_key"
      }
    }
  }
}

From Source

git clone https://github.com/rascal-3/chainanalyzer-mcp.git
cd chainanalyzer-mcp
npm install
npm start

Authentication

Choose one of three modes:

1. API Key (Subscription)

Get a tfk_ API key from chain-analyzer.com (Pro plan).

{
  "env": {
    "CHAINANALYZER_API_KEY": "tfk_your_api_key"
  }
}

2. x402 USDC Payment (Pay-Per-Request)

No account needed. Pay with USDC on Base or Solana per request.

{
  "env": {
    "X402_PRIVATE_KEY": "your_wallet_private_key",
    "X402_NETWORK": "base"
  }
}

Requires the x402 npm package: npm install x402

3. Dev Mode

No authentication. Works when the ChainAnalyzer server has X402_ENABLED=false.

{
  "env": {
    "CHAINANALYZER_BASE_URL": "http://localhost:3000"
  }
}

Environment Variables

Variable	Description	Required
`CHAINANALYZER_API_KEY`	`tfk_` API key (subscription auth)	One of API key or x402
`X402_PRIVATE_KEY`	Wallet private key for USDC payments	One of API key or x402
`X402_NETWORK`	Payment network: `base` or `solana` (default: `base`)	No
`CHAINANALYZER_BASE_URL`	API base URL (default: `https://chain-analyzer.com`)	No

Example Usage

Once configured, ask your AI agent:

"Check if this Ethereum address is sanctioned: 0x1234..."

"Analyze the risk score for this Solana wallet: ABC123..."

"Trace the fund flow of this Bitcoin transaction and check for mixing patterns"

"Screen these 20 addresses for AML compliance"

The agent will automatically call the appropriate ChainAnalyzer tools.

Supported Chains

Bitcoin — OFAC screening, dust attacks, peel chains, CoinJoin detection
Ethereum — 18+ detectors, Neo4j graph analysis, sanctions, mixers
Polygon — Full EVM AML suite, Etherscan V2 compatible
Avalanche — Full EVM AML suite, Routescan API
Solana — Token security (rug pull, honeypot), wallet drainer detection
