StealthGuard 402 🛡️ — Open-Source MCP Server for Web Scraping & Market Intelligence
[License: MIT]
[MCP Standard]
[Python]
[Base Mainnet]
[Solana Mainnet]
[Glama]
This repository contains the complete open-source Model Context Protocol (MCP) server implementation of StealthGuard 402. It equips LLM agents (Claude Desktop, Cursor, Windsurf, LangChain) with tools for Cloudflare-bypassing web scraping, prompt injection firewall sanitization, Polymarket whale orderbook divergence, and cross-chain pre-trade agent gating.
🛠️ MCP Tools Implemented
This MCP server provides the following tools via standard stdio and streamable HTTP transports:
🚀 Running from Source (Local Stdio Transport)
You can run this MCP server locally from source using Python and the Model Context Protocol SDK.
1. Installation
2. Configure with Claude Desktop
Add this server to your claude_desktop_config.json:
- macOS:
~/Library/Application Support/Claude/claude_desktop_config.json
- Windows:
%APPDATA%\Claude\claude_desktop_config.json
Or run via uv:
3. Configure with Cursor or Windsurf
Add to your workspace .cursor/mcp.json or Windsurf settings:
🌐 Connecting to the Hosted Remote MCP Endpoint

🏛️ System Architecture
📦 Developer Integrations & Autonomous Auto-Pay
StealthGuard supports 100% gasless automated settlement on Base Mainnet (eip155:8453) and Solana Mainnet (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp). Zero native gas ($0 ETH / $0 SOL) is required from your agent wallet.
1. Autonomous Agent Auto-Pay Quickstart (TypeScript)
Wrap standard fetch with @x402/fetch to automatically detect HTTP 402, sign EIP-712 payment authorization, and unlock full unredacted scrape & intelligence feeds:
2. Autonomous Agent Auto-Pay Quickstart (Python)
AI agent frameworks (LangChain, CrewAI, AutoGen) can auto-settle the 402 challenge in Python:
3. Direct REST API (cURL)
💳 Optional Cloud Subscriptions (MCPize / Apify)
