The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

check_xrpl_token unknown never probed
Live safety verdict for an XRPL token: clawback & global-freeze hard rejects, issuer blackhole status (can supply ever be re-minted?), NoFreeze, pool depth & trading fee, LP-burn fraction (is liquidity locked?), plus Cerberus's proprietary rug blocklist & detection history. Verdicts: unsafe | caution | likely_safe | unknown, with reasons. Covers BOTH XRPL fungible-token standards. `currency` may be a 3-char or 40-char hex trust-line code, OR a 48-char MPTokenIssuanceID — pass an issuance ID and the token is screened as a Multi-Purpose Token instead (issuance locked, clawback, freeze power, allow-listing, transferability, mint headroom and transfer fee), with `issuer` ignored because the issuance ID already identifies it. Price: $0.005 USDC. Missing something? Call `submit_feedback` (free) to request it. Pass `attest=true` to also get an Ed25519-SIGNED attestation of this verdict — portable proof you can log, hand to a counterparty, or verify later with `verify_attestation` (free) or the published key.

check_address unknown never probed
Cross-chain address & counterparty risk — one call before you send to, approve, or trust an address. EVM chains (ethereum, base, bsc, polygon, arbitrum, optimism, avalanche, …): sanctions, mixer, phishing, drainer, money-laundering & cybercrime flags aggregated from GoPlus, told whether it's a contract or a wallet. XRP Ledger (r-addresses): Cerberus's own engine — the production rug blocklist, live clawback/global-freeze flags (can this address seize or freeze tokens it issues?), burn-address detection, and prior launch history — coverage no incumbent offers. Chain is auto-detected; pass `chain` to pick the EVM network (default ethereum). Verdict: high_risk | caution | safe | unknown, source named. Price: $0.008 USDC. Missing something? Call `submit_feedback` (free) to request it. Pass `attest=true` to also get an Ed25519-SIGNED attestation of this verdict — portable proof you can log, hand to a counterparty, or verify later with `verify_attestation` (free) or the published key.

arguments 30 lines
check_transaction unknown never probed
Simulate an unsigned XRPL transaction and tell you what it will ACTUALLY do — before you sign it. Pass the transaction JSON; get back (1) its intent in plain language, (2) a live-ledger dry-run (`simulate`): would it succeed, and the exact balance changes per account — computed, never submitted, never signed — and (3) drain vectors flagged: handing over your signing key (SetRegularKey / SignerListSet), disabling your master key, enabling clawback, partial-payment tricks, trustlines to blocklisted issuers, sends to flagged addresses. Verdict: danger | caution | safe | unknown. A transaction that would fail on-chain is reported as such. Price: $0.010 USDC. Missing something? Call `submit_feedback` (free) to request it.

arguments 38 lines
check_endpoint unknown never probed
Endpoint & tool trust — one call before an agent connects to a third-party MCP server or HTTP tool. Pass the endpoint `url` (and, to unlock the strongest check, its `tools`: the name/description/inputSchema the agent is about to trust). Returns three signals behind one verdict: (1) transport & TLS identity — encrypted, valid chain, not expired or self-signed; (2) domain age via RDAP — freshly-registered hosts are a scam tell; (3) a TOOL-POISONING scan of the tool definitions for the hidden directives that hijack agents — instruction overrides, 'don't tell the user', data exfiltration, secret harvesting, tool-shadowing, and invisible-unicode / homoglyph steganography that a human reviewer can't see. Nobody else screens tool descriptions for injection. Verdict: trusted | caution | untrusted | unknown, with per-finding evidence. Price: $0.008 USDC. Missing something? Call `submit_feedback` (free) to request it.

token_holders unknown never probed
Holder distribution & concentration risk for an XRPL token: holder count, top-1 and top-10 share of circulating supply, AMM pool excluded from whale math. Flags single-wallet dump risk. Best for newer tokens (large tokens report 'unknown_large' honestly rather than guessing). Price: $0.008 USDC. Missing something? Call `submit_feedback` (free) to request it.

verify_issuer_domain unknown never probed
Bidirectional domain verification for an XRPL issuer: decodes the on-chain Domain field and checks the domain's /.well-known/xrp-ledger.toml actually claims the issuer back. verified true/false with reasons — a strong legitimacy signal (its absence is a yellow flag). Price: $0.003 USDC. Missing something? Call `submit_feedback` (free) to request it.

resolve_asset unknown never probed
Cross-chain identity for an XRPL token — 'what is this, everywhere it exists?' Resolves the token's real identity across chains and catches IMPOSTORS: a token using a famous symbol (USDC, WBTC, SOLO…) from an issuer that is NOT that asset's canonical deployment is flagged — a fake USDC is a fake USDC on every chain, and a single-chain check misses it. Combines XRPLMeta (the XRPL registry: name, issuer, trust_level), CoinGecko (the canonical multi-chain asset and every chain it lives on), and Cerberus's rug blocklist. Verdict: verified_crosschain | native_xrpl | impostor_suspected | unverified | unknown. Price: $0.008 USDC. Missing something? Call `submit_feedback` (free) to request it. Pass `attest=true` to also get an Ed25519-SIGNED attestation of this verdict — portable proof you can log, hand to a counterparty, or verify later with `verify_attestation` (free) or the published key.

arguments 23 lines
verify_price unknown never probed
Cross-chain value truth for an XRPL token — 'is the price real?' Reconstructs the token's USD price on XRPL (XRPLMeta price × live XRP/USD) and checks it two ways: for a stablecoin, whether the PEG still holds (is USDC actually ~$1 here?); for any cross-chain asset, whether the XRPL price has DIVERGED from its canonical price elsewhere (manipulation, stale liquidity, or arbitrage). Weighs it against real 24h volume — a price on a dead pool is a number, not a market. Verdict: price_consistent | price_divergent | depegged | thin_liquidity | native_no_reference | unknown. Price: $0.008 USDC. Missing something? Call `submit_feedback` (free) to request it.

Discover XRPL tokens — a DexScreener-style feed over 160k+ tokens. Rank by `sort` (volume_24h | marketcap | holders | trustlines | price), `query` to search by name, `limit`/`offset` to page, `trust_only` for XRPLMeta-trusted only. Each row returns name, icon, USD price, 24h volume, market cap, holder count, XRPLMeta trust level, AND our rug-blocklist flag — discovery with a trust signal built in. Run check_xrpl_token on any row for the full verdict. Price: $0.004 USDC. Missing something? Call `submit_feedback` (free) to request it.

get_token_ohlc unknown never probed
OHLC price-history candles for an XRPL token — open/high/low/close plus volume per interval, the series behind a candlestick chart. `interval` is 5 | 15 | 60 | 240 | D | W (minutes, or Day/Week); `bars` is how many candles (max 1000); prices are quoted in XRP, or pass `fx="USD"` for USD. Sourced from the XRPL DEX/AMM; returns ok:false with a reason when the pair is unknown or the source is unreachable — never invented prices. Price: $0.004 USDC. Missing something?

arguments 40 lines
get_wallet_activity unknown never probed
A readable, risk-annotated history of what an XRPL wallet did: recent transactions turned into plain language (sent/received amounts with token names, trustlines, DEX/AMM ops), with counterparties on the Cerberus rug blocklist flagged, new trustlines to blocklisted issuers flagged, and account-takeover transactions (SetRegularKey, SignerListSet, master-key disable) surfaced as notable — watching your OWN wallet is compromise detection. Returns XRP balance, a summary (in/out counts, distinct and flagged counterparties, notable events), and a `marker` to page further back. Read-only. Price: $0.008 USDC. Missing something? Call `submit_feedback` (free) to request it.

arguments 18 lines
analyze_token_trend unknown never probed
A data-driven technical read on an XRPL token. Computes real indicators from OHLC — trend (9/21 EMA), RSI momentum, support/resistance, volatility, volume trend — with a plain-language assessment, and (when the server has an LLM configured) an AI-written outlook plus a genuine counter-argument. `interval` is 5|15|60|240|D|W, `bars` how many candles. Returns `ai_available` so you know whether the narrative is live. Always an informational signal, NEVER financial advice or a price target. Price: $0.020 USDC. Missing something?

find_best_path unknown never probed

Find the safest EXECUTABLE route to acquire an XRPL token and screen every hop. Unlike quote_amm (one direct AMM pool), this asks the ledger for real payment paths (order books + AMM + multi-hop) and runs the rug-safety engine over every issuer and gateway the route touches — a clean token reached through a hop that can freeze or claw back mid-route is a trap a destination-only check misses. Returns the cheapest route, its effective price, hop count, and a verdict: route_safe | route_caution | route_unsafe | no_route, with the risk on each hop. Pass your `account` for routes specific to your trustlines, or omit it for an indicative route. Price: $0.006 USDC. Missing something? Call `submit_feedback` (free) to request it.

watch_token unknown never probed
Monitor an XRPL token you hold and get alerted when it turns dangerous. A one-time check can't catch a rug that happens later — this watches the chain continuously for: AMM pool destroyed (completed rug), liquidity drained past your threshold, clawback enabled, global freeze set, issuer un-blackholed (supply re-mintable), issuer blocklisted, LP lock weakened. Returns a `subscriber_key` — STORE IT — then poll `check_alerts` (free). Registration is refused (with the reason) for tokens that are ALREADY compromised — blocklisted, clawback-enabled, frozen, or a husk pool — since those need a verdict now, not monitoring later. Sold as packages by monitoring window (`duration_days`): 1d $0.005 · 3d $0.012 · 7d $0.020 · 14d $0.035 · 21d $0.048 · 30d $0.060 USDC (longer = cheaper per day). The x402 payment demand lists every tier; pay the one you want and the watch length is set by what you pay. Calling again renews (extends) the watch. Missing something?

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
