Installation

In SourceWeft

  1. Open Criptonlabs Agent APIs in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.criptonlabs%2Fagent-apis/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

16

xrpl_fee

Fee intelligence

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 {}

Takes no parameters.

xrpl_network_health

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 {}

Takes no parameters.

xrpl_orderbook

Funded order book

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_orderbook {"base":"XRP","quote":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}

Parametersbaserequireddepthquoterequired

xrpl_slippage

Slippage estimate

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 amount across venues or route through other pairs. To read pool reserves, use the amm page. Example: xrpl_slippage {"base":"XRP","quote":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh","amount":"1000"}

Parametersbaserequireddepthquoterequiredamountrequired

xrpl_amm

AMM pool

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":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}

Parametersarequiredbrequired

xrpl_account_summary

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_account_summary {"address":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}

Parametersaddressrequired

xrpl_account_lines

Account trust 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}/summary`; for issued totals of a token, use the token endpoint. Example: xrpl_account_lines {"address":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}

Parameterspeerlimitmarkeraddressrequired

xrpl_account_transactions

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/{address}/summary` or `/v1/xrpl/account/{address}/lines`; for full archival history, use a full-history node or indexer: history depth depends on the serving node and older pages may be slower. Example: xrpl_account_transactions {"address":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}

Parameterslimitmarkeraddressrequired

xrpl_token

Token issuer

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 another tool: For XRP (not an issued asset; 400), for one account's own balances use `/v1/xrpl/account/{address}/lines`, and for prices use `/v1/xrpl/orderbook` or `/v1/xrpl/amm/{a}/{b}`. Example: xrpl_token {"asset":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}

Parametersassetrequired

xrpl_payment_readiness

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. Prefer another tool: To find a multi-hop route or the source amount needed for a cross-currency payment (use the paths endpoint), or to list balances (use `/v1/xrpl/account/{address}/summary`). Example: xrpl_payment_readiness {"source":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh","destination":"rvYAfWj5gh67oV6fW32ZzP3Aw4Eubs59B"}

Parametersassetamountsourcerequireddestinationrequireddestination_tag

xrpl_paths

Payment 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 whether a direct payment can succeed (use `/v1/xrpl/payment-readiness`), or for the single-hop cost of a trade on one pair (use `/v1/xrpl/slippage`, which compares the order book and the AMM). Example: xrpl_paths {"source":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh","destination":"rvYAfWj5gh67oV6fW32ZzP3Aw4Eubs59B","asset":"XRP","amount":"1"}

Parametersassetrequiredamountrequiredsourcerequiredsend_maxdestinationrequiredsource_assetssend_max_asset

xrpl_latest_ledger

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 {}

Takes no parameters.

solana_transfer_readiness

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 program logic), not a token price or holder lookup, and not a way to read raw accounts. Example: solana_transfer_readiness {"source":"83astBRguLMdt2h5U1Tpdq5tjFoJ6noeGwaY3mDLVcri","destination":"A1TMhSGzQxMr1TboBKtgixKz1sS6REASMxPo1qsyTSJd","mint":"SOL","amount":"0.5"}

Parametersmintrequiredamountrequiredsourcerequireddestinationrequired

solana_token

Solana token verdict

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 token's project; it reads only the mint account. Example: solana_token {"mint":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"}

Parametersmintrequired

solana_latest_slot

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 {}

Takes no parameters.

solana_network_health

Solana data status

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 endpoint to see chain progress. Example: solana_network_health {}

Takes no parameters.
