Verify a skill, tool, or package for malicious behavior before your agent installs it. Hosted.

JWT-gated LLM gateway: authenticate (bcrypt/JWT), then run a LangChain-on-Vertex Gemini completion.

Google-OAuth-gated LLM gateway: verify a Google ID token, then run a Gemini (Vertex AI) completion f

Deterministic gate for AI agents: ALLOW/DENY a step before it runs, sealed to a verifiable receipt.

Scan any public site for AI-agent visibility; get scored findings, a machine-readable fix pack, and

Personalised developer security learning pathways from SecDim's challenges and courses.

Domain intelligence platform that turns your LLM into a professional domain consultant.

Promotion gate for AI agents: leakage audits, exact-statistics verdicts, and a live report card.

Detects and redacts PII (emails, phones, SSNs, names, addresses) from text. $0.02/call via x402.

Search a directory of SOC 2 audit and compliance firms; read GRC migration guides. Read-only.

Validate whether an IP address belongs to Applebot. Remote MCP server exposing a validate_ip tool.

Pre-signature x402 payment-risk oracle. AI agents call forecast_payment before paying a counterparty and get a GO / HOLD / STOP verdict from settlement reputation, price-anomaly (quoted vs the payee's own median), and OFAC sanctions screening — plus a third-party-verifiable Ed25519 signed receipt. Verdict only; never takes custody. Free under $10 at risk; returns an x402 payment challenge over that.

Scans text for personally identifiable information — emails, phone numbers, SSNs, credit card numbers, physical addresses, names — and returns a redacted version. Built for agents sanitizing user content, support tickets, logs, or documents before storage, sharing, or feeding into another LLM call. Pay-per-call via x402 (USDC on Base): $0.01/call, no account or API key. tools/list and /openapi.json are free for discovery.
