# Rug-Check-MCP
An MCP server that detects potential risks in Solana meme tokens, helping AI agents avoid rug pulls and unsafe projects.
[](https://smithery.ai/server/@kukapay/rug-check-mcp)
## Features
- **Token Analysis Tool**: The `analysis_token` tool retrieves and processes Solana token data from the Solsniffer API.
- **Structured Output**: Returns detailed token information including name, symbol, Snif score, market cap, price, supply, risks, and audit status.
## Prerequisites
- Python 3.10 or higher
- A Solsniffer API key (sign up at [Solsniffer](https://solsniffer.com) to obtain one)

## Tool: `analysis_token`
- **Description**: Analyzes a Solana token based on its address.
- **Input**: `token_address` (string) - The Solana token address to analyze.
- **Output**: A dictionary containing:
- `token_address`: Token address
- `token_name`: Token name
- `token_symbol`: Token symbol
- `snif_score`: Solsniffer risk score (0-100)
- `market_cap`: Market capitalization in USD
- `price`: Token price in USD
- `supply_amount`: Total supply of the token
- `risks`: High, moderate, and low risk details with counts and descriptions
- `audit_risk`: Audit status (mint/freeze disabled, LP burned, top 10 holders)
### Example Output
