Free /mcp; x402 /mcp/pro. ## Connect - streamable-http: `https://api.criptonlabs.com/mcp` - streamable-http: `https://api.criptonlabs.com/mcp/pro` ## Tools (as reported by the server, not verified) - `xrpl\_fee`: Current XRPL fee tiers in drops with a congestion score. When to use: Before submitting a transaction, to choose a \`Fee\` and to decide whether the network is congested. Prefer another tool: Not a price feed and not a historical series; it describes the latest validated ledger only. Example: xrpl\_fee - `xrpl\_network\_health`: Overall and per-node health of the upstream XRPL nodes. When to use: To decide whether to trust or retry data, or to explain a 503 from another endpoint. Prefer another tool: Not a probe of your own connectivity; it reports the service's upstream nodes. Example: xrpl\_network\_health \{\} - `xrpl\_orderbook`: CLOB order book for a currency pair with unfunded offers removed. When to use: To read executable liquidity for a pair on the XRPL central limit order book \(CLOB\). Prefer another tool: Not for AMM liquidity \(use the amm page\) and not for a cost estimate \(use the slippage page\). Example: xrpl\_orderbo - `xrpl\_slippage`: Slippage and average price for buying an amount of base currency. When to use: Before placing a market-style trade, to size it against available depth and to see whether the CLOB or the AMM pool is the cheaper venue. Prefer another tool: It is an estimate, not a quote, and it does not split an amoun - `xrpl\_amm`: AMM pool reserves and trading fee for an asset pair. When to use: To read AMM pool depth and fee for a pair. Prefer another tool: It does not estimate slippage or compare venues \(use the slippage page for the CLOB vs AMM comparison\); a pair without a pool returns 404. Example: xrpl\_amm \{"a":"XRP","b - `xrpl\_account\_summary`: XRP balance, sequence, owner count, transfer rate and trust lines \(capped\) for an account. When to use: To inspect an account before building a transaction for it. Prefer another tool: Not for transaction history, reserves or account flags; it is a summary, not a full account dump. Example: xrpl\_acc - `xrpl\_account\_lines`: One page of an account's trust lines, with an opaque cursor for the next page. When to use: To list every trust line of an account \(balances, limits, freeze and authorization flags\), page by page. Prefer another tool: For a quick capped overview with the XRP balance, use \`/v1/xrpl/account/\{address\}/ - `xrpl\_account\_transactions`: One page of an account's most recent validated transactions, newest first. When to use: To check what an account did recently \(payments sent or received, offers, trust line changes\) and whether each transaction succeeded. Prefer another tool: For balances and trust lines, use \`/v1/xrpl/account/\{addr - `xrpl\_token`: Issuer data for an issued asset: flags, domain, transfer fee and total issued. When to use: Before accepting or sending an issued token: check that the issuer exists, is not frozen, whether holders need authorization, and the transfer fee charged on every transfer between non-issuer accounts. Prefer - `xrpl\_payment\_readiness`: Pre-payment check: can this payment from source to destination succeed now? When to use: Right before sending a payment: to catch a missing or unfunded destination, a required destination tag, deposit authorization, missing or frozen trust lines, insufficient balance and issuer freezes, in one call. - `xrpl\_paths`: Multi-hop payment paths and their source cost. When to use: Before a cross-currency or multi-hop payment: to see whether a route exists and how much the source would spend to deliver the amount. A call can take up to about 20 seconds and paths may be non-optimal. Prefer another tool: To check whethe - `xrpl\_latest\_ledger`: Latest validated ledger index, hash and close time. When to use: To anchor other readings to a ledger or to check how current the network view is. Prefer another tool: Not for transaction data or account state; use the account endpoint for those. Example: xrpl\_latest\_ledger \{\} - `solana\_transfer\_readiness`: Will this Solana transfer succeed? A verdict for SOL or an SPL or Token-2022 token. When to use: Before building or signing a Solana transfer, to learn whether it will fail and what it will cost in rent and fees. Prefer another tool: Not a simulation of the exact transaction \(no priority fee, no pro - `solana\_token`: Is this Solana token safe to hold or receive? A SAFE, WARN or DANGER verdict. When to use: Before accepting or swapping into an unfamiliar token, to see whether its mint can freeze, mint more, move or tax balances. Prefer another tool: Not a price, liquidity or holder lookup and not an audit of the - `solana\_latest\_slot`: Latest finalized Solana slot and its block time. When to use: To check how fresh the finalized view of Solana is, or to anchor a read to a slot. Prefer another tool: Not a tip-of-chain feed: it is finalized, not processed or confirmed, and it is cached for 2 seconds. Example: solana\_latest\_slot \{\} - `solana\_network\_health`: Whether Solana data is currently being served: latest probe status and finalized slot. When to use: Before relying on the Solana verdict endpoints, or to explain a 503 from them. Prefer another tool: Not a measure of the Solana network itself, only of this service's access to it; use the latest-slot Measured by MCP Station.
