## Supported GoPlus Tools

This MCP server provides the following GoPlus security analysis tools:

### Core Security Analysis Tools

- **`token_security`** - Analyze token security for EVM-compatible blockchains with comprehensive risk assessment including honeypot detection, liquidity analysis, and holder concentration

- **`malicious_address`** - Detect malicious addresses and potential scams across multiple blockchains with real-time threat intelligence

- **`phishing_website`** - Detect phishing websites and malicious URLs in the crypto space using GoPlus's extensive database

- **`nft_security`** - Analyze NFT contract security and detect potential risks with optional specific token analysis

- **`approval_security`** - Analyze token approvals and detect potential security risks for user addresses

### Multi-Chain Support Tools

- **`solana_token_security`** - Analyze Solana token security including mint authority, freeze capability, and metadata mutability

- **`sui_token_security`** - Analyze Sui token security including contract upgradeability and capability ownership

## Tool Parameters

### EVM-Compatible Chain Tools
**Parameters for `token_security`, `malicious_address`, `nft_security`, `approval_security`:**
- `chain_id`: Blockchain ID (see supported chains table above)
- `contract_addresses` or `addresses`: Contract/wallet address(es) to analyze (comma-separated for multiple)
- `token_id` (NFT only): Optional token ID for specific NFT analysis

### Cross-Chain Tools
**Parameters for `phishing_website`:**
