One question. Four layers.
Every autonomous agent faces the same moment: about to buy, send, sign, or call something irreversible. This suite exists for that moment — and it's built in the open, layer by layer.
Token safety — XRP Ledger
LIVE“Is this token going to rug me?”
Live verdicts composed from clawback & global-freeze hard rejects, issuer blackhole status, LP-burn fraction, pool depth, and a proprietary rug blocklist earned in production. Serving now, per-call. Try it →
Address & counterparty risk
LIVE“Is this address a scam, drainer, mixer, or sanctioned?”
Cross-chain address screening, agent-native: per-call, MCP, x402. EVM sanctions/mixer/drainer/phishing flags in one call — plus live XRPL address risk (rug blocklist, clawback & freeze powers, burn detection) that no incumbent covers. Try it →
Transaction intent
LIVE“If my agent signs this, what actually happens?”
Pre-sign simulation as a metered tool: dry-run an unsigned XRPL transaction against the live ledger for its exact balance changes, plus a scan for drain vectors — key handover, master-key disable, clawback, partial-payment tricks — before the signature, not after. Try it →
Endpoint & tool trust
PLANNED“Is this x402 endpoint or MCP tool safe to pay and call?”
The layer nobody built: endpoint reputation, MCP tool-poisoning scans, and agent reputation — trust infrastructure for the rails this service itself runs on.
Maturity labels are honest: LIVE means deployed and serving real calls now.
Nothing planned is presented as shipped. Want a layer sooner? The free
submit_feedback tool is how agents vote — demand decides build order.

Why agents use this
Verdicts, not raw data
Every tool returns
verdict · confidence · reasons[] — a decision an agent can act on in one
hop, not a data dump to interpret. Learn the schema once, use every layer.
Production-grade signals
The screening logic comes from a live XRPL trading pipeline: issuer blackhole checks, clawback hard-rejects, LP-burn verification. The blocklist contains rugs we caught with real money on the line.
Every check makes it smarter
Usage is metered, feedback is ranked, and each screened token or issuer feeds the threat data. More agents → better verdicts → more agents. Knowledge compounds.
The coverage gap
Token-security APIs (GoPlus, Webacy) stop at EVM chains and Solana. The XRP Ledger — with its own AMM and its own rug mechanics — had no equivalent. Now it does, built agent-native from day one.
Quickstart
Point any MCP client at https://cerberusindex.com/mcp and call a tool. Unpaid
calls return x402 payment terms; x402-aware clients pay in USDC and retry automatically.
