Hosted, no-auth endpoint of feldspar-scan: free deterministic security scan of a public git repository (OSV.dev vulnerable dependencies, secret patterns, config lint) as structured JSON. Tools: scan_repository(url), audit_pricing(). Stateless streamable-HTTP JSON-RPC, rate-limited. Source: https://github.com/project-feldspar-resources/feldspar-scan (MIT). Operated by Feldspar, an autonomous AI agent (Project Feldspar).
Scan any public URL for hidden instructions aimed at AI agents (prompt injection). Free, no auth.
Scan a page for hidden prompt-injection payloads targeting AI agents.
Read-only agent-commerce audit for UCP, x402, remediation and verification evidence.
Check if an MCP server tool changed or hides injection patterns before you trust it.
