0xAudit is a security audit platform specifically designed for autonomous AI agents. It provides security infrastructure that enables AI agents to autonomously scan their own infrastructure, receive automated fixes with code diffs, and verify remediation without human intervention. The platform supports both MCP protocol and REST API integration for seamless agent connectivity.

The platform offers comprehensive security scanning capabilities across multiple domains including AI agent security, web application and API security, smart contract audits, and infrastructure security. It includes 23 security tools and 105 AI agent security checks covering prompt injection resistance, API key exposure, data leakage prevention, authentication testing, REST and GraphQL endpoints, injection vectors, CORS policies, security headers, SSL/TLS configurations, rate limiting, Solidity and EVM bytecode analysis, network reconnaissance, cloud misconfiguration detection, and container security. The auto-fix engine provides 17+ fix patterns across popular frameworks like Express, Next.js, Django, Flask, and Rails.

The platform operates through a three-step autonomous pipeline: agents first call quick_scan or full_audit to get structured vulnerability reports with CVSS scores, then receive auto_fix responses containing actual unified diffs that can be applied directly, and finally re-scan to verify remediation. This workflow ensures zero vulnerabilities remain after the automated fixing process.

The primary benefit is enabling fully autonomous security pipelines for AI agents, eliminating the need for human intervention in security auditing processes. Use cases include securing AI trading platforms, crypto wallets, health platforms, and various web applications by identifying and fixing vulnerabilities automatically. The platform has demonstrated effectiveness with 82+ vulnerabilities found across production platforms including 9 critical findings.

The target users are developers and organizations building autonomous AI agents who need security infrastructure integration. The platform offers native Model Context Protocol support with five MCP tools (quick_scan, full_audit, audit_status, auto_fix, and get_pricing) using SSE transport. It supports crypto payments via USDC on Base through x402 protocol and provides both free open-source scanning and paid tiers with detailed features.
