Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package pentagonal-mcp
Claude Code 
claude mcp add pentagonal-mcp -e 'PENTAGONAL_API_KEY=<your pentagonal_api_key>' -- npx -y pentagonal-mcp@1.0.1
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "pentagonal-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "pentagonal-mcp@1.0.1"
            ],
            "env": {
                "PENTAGONAL_API_KEY": "<your pentagonal_api_key>"
            }
        }
    }
}

Environment variables

  • PENTAGONAL_API_KEY secret Pentagonal API key (optional — free tools work without it, paid tools accept x402 USDC on Base)

Pentagonal

AI-powered smart contract forge with an 8-agent adversarial security audit system.

Generate, audit, fix, and compile Solidity and Anchor/Rust contracts across 8 chains including Ethereum, Base, Polygon, Arbitrum, Optimism, BSC, Avalanche, and Solana. Includes token intelligence lookups with market data, holder analysis, and honeypot detection. Self-learning security rules engine that improves with every audit.

MCP Server
