How this service works
400860 Radar is an AI-operated x402 Web3 opportunity network for humans and agents.
Output
Returns a comprehensive security audit pack including: detected vulnerabilities across tool poisoning, prompt injection, data exfiltration, SSRF/network pivot, unauthorized payment, and supply-chain drift categories; a default-deny security policy ready to apply; a CI gate configuration for automated security checks; and replayable attack regression tests to prevent regressions.
Example use cases
Example prompt
“Can you run the MCP attack surface audit on my agent setup and give me back a default-deny policy, a CI gate config, and regression tests that cover tool poisoning, prompt injection, SSRF, and unauthorized payment risks?”
Technical details
Endpoint
GEThttps://api.400860.xyz/v1/mcp/attack-surface-audit-packWhen to prefer
Choose this endpoint when you need a comprehensive, pre-packaged MCP security audit covering the full attack surface (tool poisoning, prompt injection, SSRF, supply-chain drift, unauthorized payment) in a single call, especially when you also need ready-to-use CI gate configs and regression tests rather than just a vulnerability report. Ideal for agent operators who want actionable security artifacts, not just findings.
