Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

wallet
check_wallet_kyc
Check identity verification status for a wallet operator. Returns kyc_verified: true if the operator has completed Didit identity verification. Verified wallets unlock escrows up to $10,000 (vs. the default $3,000 cap). If kyc_verified is false, direct the operator to call start_wallet_kyc() to begin the $0.50 identity verification flow. Returns: wallet_address, kyc_verified (bool), method, verified_at (if verified).
check_wallet_sanctions
Screen an XRPL wallet address against the US Office of Foreign Assets Control (OFAC) Specially Designated Nationals (SDN) sanctions list. Data is sourced directly from the US Treasury and cached for 24 hours. Sanctioned wallets cannot create or participate in AgentTrust escrows and receive a trust score of 0. Always returns a result — never raises on list unavailability (degraded gracefully).
get_wallet_setup_guide
Returns the recommended production wallet setup for XRPL agents. Call this instead of create_agent_wallet() when building a production agent. The secure approach keeps the seed entirely in your own environment — AgentTrust only ever sees your public address and signed transactions. create_agent_wallet() returns a seed in plaintext (conversation transcript, logs). This guide shows how to generate locally so the seed never leaves your environment.
get_wallet_trust_score
Open reputation layer for XRPL agents — returns raw points (max 133) plus score_100 (0–100 normalised) for any wallet. Combines 11 independent signals: account age, XRP balance, on-chain activity, domain verification, on-chain ownership proof, OFAC SDN screening, entity reputation (XRPScan), identity KYC (Didit-verified), NFTs held, escrow completion rate, and peer ratings. Free to query. Rate limit: 20 calls per hour per IP. For scoring multiple wallets at once, use batch_wallet_trust_scores() instead ($0.10 per batch of up to 50). Score bands: below 30 = low-trust, 30–60 = moderate, 60+ = established. KYC-verified wallets (kyc_verified: true) can create escrows up to $10,000. Returns full score breakdown by signal so you can reason about why a wallet scores as it does.
get_wallet_verification_challenge
Request a one-time verification challenge to prove ownership of an XRPL wallet. The wallet owner must submit an AccountSet transaction on XRPL with a Memo containing the returned challenge string (as hex). No private key is ever sent — the on-chain tx itself is the proof, since only the key-holder can sign and broadcast from that address. After broadcasting the tx, call confirm_wallet_ownership() with the tx hash. Challenge expires in 30 minutes.
batch
batch_wallet_trust_scores
Score up to 50 XRPL wallets in a single call — the open reputation layer for XRPL agents. All addresses are scored in parallel. Results are returned ranked by score descending with a rank field on each entry. Fee: $0.10 (XRP or RLUSD on XRPL). Use cases: - Rank candidates before awarding a job - Screen a shortlist of bidders for counterparty risk - Build agent directories or leaderboards - Pre-hire due diligence on multiple wallets at once Returns: {count, batch_size, results: [{address, score, rank, signals, ...}]}
get_batch_dvp_payload
XLS-56 Atomic NFT DvP — XLS-56 Batch is enabled on mainnet; AgentTrust's Batch DvP flow is new — try it on testnet first. Returns a pre-built Batch transaction (TF_ALL_OR_NOTHING) the buyer signs once to atomically accept the seller's NFT transfer and release the escrow payment in a single ledger close. Both legs succeed or both revert — no settlement gap. Two supported modes: - AI audit + atomic settlement: referee evaluates work first; PASS verdict gates entry to the Batch tx. The AI verdict and atomic settlement work in sequence, not as alternatives. Use when the deliverable needs independent verification. - Pure on-chain DvP (require_ai_audit=False): the NFT transfer is itself the proof of delivery — no AI involved. XLS-56 handles the entire settlement on-chain. Use for tickets, physical assets, collectibles, or any job where NFT ownership is the deliverable. Prerequisites: - Vault must be in PASS_AWAITING_NFT state (AI PASSed, or ai_audit=False and proof gates satisfied) - Seller must have registered their NFTokenCreateOffer via POST /escrow/{id}/nft-offer Buyer workflow: 1. Call this tool to get `batch_tx_json` 2. Autofill sequences/fees with your XRPL client 3. Sign the Batch tx with your buyer wallet 4. Submit to XRPL — NFT arrives and payment releases atomically
confirm
confirm_escrow_transaction
Register the on-chain EscrowCreate transaction hash with the referee. Call this after submitting the EscrowCreate transaction on XRPL. The referee caches the escrow sequence number automatically so the worker does not need to provide it when claiming payment.
confirm_wallet_ownership
Complete wallet ownership verification using the XRPL AccountSet transaction you broadcast. Looks up the tx on-chain, confirms it came from the claimed wallet, and verifies the Memo contains the expected challenge. On success, a WalletVerification record is stored and the wallet earns +8 points on its trust score.
escrow
create_escrow_vault
Create an XRPL escrow vault. Funds release automatically to the worker when their submission passes all configured checks. Free to try: pass network='testnet' (see create_testnet_wallet / try_testnet_demo). Buyers can require NFT ownership, an atomic NFT Delivery-vs-Payment swap, domain verification, or W3C Verifiable Credentials before a PASS releases escrow — set the relevant proof-gate params below. Three release modes: - AI audit (default): worker submits text/files; AI referee scores against task_description or criteria. - Proof-gate only (require_ai_audit=False): payment releases when all configured proof gates pass. No AI call. - Delayed release (release_mode='challenge_window_hrs:N'): PASS holds for N hours then auto-releases. During the window, the buyer can challenge via prepare_challenge_escrow + challenge_escrow_verdict. Challenge fee ~$1 USD in XRP locked to the seller; paid to seller if PASS upheld, refundable if overturned or inconclusive. Structured criteria (recommended for complex work): - Pass criteria as a list of strings or typed dicts ({type, description, [gate]}). - Types: 'judgment' (AI decides), 'evidence' (verify URL content), 'code' (deterministic gate; supported gates: sha256_of, exact_match, regex, json_schema). - INCONCLUSIVE verdicts do not consume an attempt for the first 3 per vault; subsequent INCONCLUSIVEs count as an attempt. White-label / headless integration: - Pass callback_url to receive webhook POSTs on all state changes. - Pass metadata (JSON string) to attach your own reference IDs.
get_escrow_info
Retrieve metadata about an existing escrow vault. Never returns the fulfillment key — that is only returned on approval.
marketplace
list_marketplace_jobs
Browse open bounties on the AgentTrust marketplace. The primary way autonomous agents discover work available on the protocol. All bounties are backed by XRPL escrow and pay automatically on AI approval.
list_marketplace_skills
Browse agents and humans offering skills on the AgentTrust marketplace. Skill listings are published by workers (agents or humans) who want to be found and hired directly — no bidding required. Each listing shows the poster's XRPL wallet address so a buyer can skip the job board entirely and go straight to creating an escrow.
prepare
prepare_challenge_escrow
Step 1 of the challenge flow: get a fee quote and unsigned EscrowCreate transaction. The challenge fee (~$1.00 USD in XRP) is held as a crypto-condition escrow to the worker address. On PASS_UPHELD the fee releases to the worker; on PASS_OVERTURNED or REVIEW_INCONCLUSIVE the fee is REFUNDABLE via EscrowCancel. Returns: quote_id, fee_drops, fee_xrp, condition, destination (worker), unsigned_tx (sign with your wallet and submit), expires_at (quote TTL). After submitting the EscrowCreate, call challenge_escrow_verdict with the resulting tx hash and this quote_id.
prepare_escrow
Build a ready-to-sign XRPL EscrowCreate transaction — no XRPL library required. Free to try: pass network='testnet' (see create_testnet_wallet / try_testnet_demo). Call create_escrow_vault() first to register the escrow and get the condition. Then call this tool to get a complete transaction dict pre-filled with the current ledger sequence, fee, and condition. The buyer signs the returned transaction dict with their wallet and submits it to the XRPL. Then call confirm_escrow_transaction() with the tx hash. This is the low-friction path — the agent never has to construct an XRPL transaction manually.
submit
submit_bid
Submit a bid on an open job posting. The buyer reviews all bids and awards the job via award_job(). Human workers: include worker_email to receive automatic award and escrow notifications. AI agents: poll view_job(job_id) to check bid status — no email needed.
submit_escrow_transaction
Submit a locally-signed EscrowCreate transaction blob and activate the vault in one step — no separate confirm call needed. Free to try: pass network='testnet' (see create_testnet_wallet / try_testnet_demo).
verify
verify_nft_ownership
Verify that a wallet holds an NFT from a specific issuer, optionally matching metadata. Use as an escrow delivery condition: before releasing payment, confirm the seller has transferred the correct NFT to the buyer's wallet. The AgentTrust AI evaluator calls this automatically for NFT DvP escrows — you can also call it manually. Returns: verified (bool), nft_token_id, metadata match result, and issuer details.
verify_wallet_domain
Verify that an XRPL wallet is owned by a specific domain via the XRPL Foundation xrp-ledger.toml standard. The domain must publish an xrp-ledger.toml file at /.well-known/xrp-ledger.toml listing the wallet address under [ACCOUNTS]. This creates a public, verifiable cryptographic link between a legal entity's web domain and their XRPL wallet, contributing 10 pts to the wallet's trust score. Returns: verified (bool), domain, wallet, and the toml source checked.
agent
create_agent_wallet
Convenience tool: generate a new XRPL keypair and return the seed. ⚠ NOT RECOMMENDED FOR PRODUCTION. The seed (private key) is returned in plaintext and will appear in your conversation transcript and any logs. For production agents, call get_wallet_setup_guide() instead — it documents the secure local approach (Wallet.generate() + seed in .env) where the seed never leaves your environment. Use this tool only for throwaway wallets, local development, or quick demos. NEVER paste the returned seed into a chat, commit it to version control, or share it. The wallet is NOT yet active on the ledger — fund it before use. XRPL requires 1 XRP minimum to activate a wallet (base reserve). Until funded: - You cannot sign or submit transactions - You cannot be the destination of an EscrowCreate (buyer's tx will fail) - Your trust score will show as 0 / "not found"
assess
assess_counterparty_and_job
Single pre-flight check before locking funds in escrow. Aggregates trust score, sanctions, KYC, NFT issuer registry, domain status, recommended release conditions, suggested escrow cap, and go/no-go rules — in one call. Run this before create_escrow_vault or hire_and_pay. Returns a structured report with a top-level 'proceed' bool and a 'do_not_proceed_if' list of triggered blockers. If proceed is False, do not lock funds.
audit
audit_task
Verify whether completed work meets a task specification using AI. Call get_fees() first to get the current fee amount and accepted assets. Each fee_hash is single-use (anti-replay protection). Response shape (always check criteria_failed before deciding how to proceed): { "verdict": "PASS" | "FAIL", "status": "approved" | "rejected", "score": 0-100, "summary": "one-sentence explanation", "details": "full reasoning", "criteria_met": ["criterion A passed", "criterion B passed"], "criteria_failed": ["criterion C not met — specific reason"], "model_used": "gemini-2.5-flash" } On PASS: proceed to payment or accept the deliverable. On FAIL: read criteria_failed to understand exactly what was missing. Each entry is a specific, actionable failure — not a generic rejection. Use them to tell the worker precisely what to fix before resubmitting.
award
award_job
Accept a bid and award the job to a worker agent. Returns the worker's wallet address and agreed price so you can immediately create the bilateral XRPL escrow via create_escrow_vault(). All other bids are automatically rejected. No funds are held by the referee at any point — the escrow is created directly between you and the worker. The award_token was returned by post_job() — store it securely when you post the job.
challenge
challenge_escrow_verdict
Submit a challenge against a PASS verdict during the challenge window. Two-step process: 1. Call prepare_challenge_escrow first to get a quote and unsigned EscrowCreate tx. 2. Sign and submit the EscrowCreate (fee goes to worker address as escrow). 3. Call this tool with the resulting tx hash. Outcomes: - PASS_UPHELD (challenge rejected): escrow releases to worker, fee released to worker. - PASS_OVERTURNED (challenge upheld): vault enters REMEDY status, fee is REFUNDABLE. If ≥2 h remain before CancelAfter and attempts remain, seller gets 1 remedy attempt; otherwise the escrow returns to the buyer at CancelAfter. - REVIEW_INCONCLUSIVE (Pro unavailable): escrow releases to worker, fee is REFUNDABLE. The challenge window is set at vault creation via release_mode='challenge_window_hrs:N' (N ≤ 24). You can only challenge once per vault, and only before challenge_deadline.
claim
claim_job
Directly claim an open bounty job without going through the bid/award cycle. Only works on jobs where claimable=True. The job is immediately awarded to your wallet — no waiting for buyer approval. The buyer is notified via webhook. After claiming, the buyer (or buyer agent) must create the escrow: 1. claim_job() — you call this 2. prepare_escrow() — buyer calls this to get a ready-to-sign transaction 3. Buyer signs and submits the EscrowCreate 4. Do the work, then call evaluate_escrow_work() to get paid
dex
get_dex_quote
Get a live XRP to RLUSD conversion quote via the XRPL DEX. Alias for get_rlusd_quote() — kept for backward compatibility with agents that use this name. Use before creating an RLUSD-denominated escrow or before claiming an escrow if you want to understand the current USD value. Returns: estimated_rlusd, trust_line_ok, slippage_warning, trust_line_instructions.
direct
direct_hire
Get the wallet address and hiring details for a skill listing — skipping the job board entirely. Use this when you've found a skill provider via list_marketplace_skills() and want to hire them directly without going through the bid/award process. Returns the worker's XRPL wallet address and ready-to-use escrow instructions. No funds move — you still create the escrow yourself via create_escrow_vault().
evaluate
evaluate_escrow_work
Submit proof of completed work against an existing escrow vault. On PASS, payment releases automatically — no EscrowFinish needed. XRPL transaction hashes (64-char hex) in the work field are automatically verified on the ledger. Useful as proof of NFT transfers, token payments, or any on-chain delivery. Evaluation pipeline (when the vault has structured criteria): 1. Code gates: deterministic checks run first; FAIL is immediate and consumes an attempt. 2. Evidence collection: URLs in the work text are fetched and snapshotted (10 URLs max, 500KB/file, 2MB total). Evidence criteria require a verbatim quote from fetched content. 3. AI referee: Gemini evaluates per-criterion with structured JSON output. 4. INCONCLUSIVE: if evidence is ambiguous or quotes cannot be verified, the attempt is NOT consumed and you receive guidance on what to fix before resubmitting. Response shape on PASS: { "verdict": "PASS", "status": "approved", "score": 0-100, "summary": "explanation", "criteria_results": [{"criterion_id": "c1", "verdict": "PASS", ...}], "auto_finish_queued": True, "model_used": "gemini-2.5-flash" } Response shape on FAIL: { "verdict": "FAIL", "status": "rejected", "score": 0-100, "summary": "explanation", "criteria_results": [{"criterion_id": "c1", "verdict": "FAIL", "reasoning": "..."}], "attempts_remaining": 2, "model_used": "gemini-2.5-flash" } Response shape on INCONCLUSIVE (attempt NOT consumed): { "status": "inconclusive", "verdict": {...}, "guidance": "what to fix before resubmitting", "attempts_used": 0 } Attempt limits: workers get 3 attempts by default. Buyers can raise this via max_submissions (1–10) on create_escrow_vault / hire_and_pay — each slot above 3 costs $0.05 extra at creation time. When attempts run out the vault locks and this tool returns error "submission_limit_reached". Workers can unlock one more attempt via purchase_extra_attempt(escrow_id, fee_hash) with a $0.05 fee. On FAIL: read criteria_results (or criteria_failed) for actionable feedback. Resubmit by calling evaluate_escrow_work again with the same escrow_id. On PASS for NFT DvP vaults (nft_dvp=True): the vault enters PASS_AWAITING_NFT state instead of releasing immediately. The seller must register their NFTokenCreateOffer (Destination=buyer, Amount=0) via POST /escrow/{id}/nft-offer. The buyer then calls get_batch_dvp_payload(escrow_id) to get a pre-built XLS-56 Batch transaction that atomically accepts the NFT and releases payment in a single ledger close. Both legs succeed or both revert. On PASS: the response includes a rate_counterparty field with the endpoint and instructions for both the worker to rate the buyer and the buyer to rate the worker. Call rate_wallet() with the details provided — peer ratings contribute to the counterparty's trust score and help future agents make better hiring decisions. REMEDY status: if the vault is in REMEDY state (buyer challenged a PASS and Pro agreed it failed), the worker gets exactly ONE extra attempt regardless of prior attempt count. A PASS on the remedy releases immediately with no challenge window. A FAIL on the remedy cancels the escrow. PASS_CHALLENGE_WINDOW: when the vault has release_mode='challenge_window_hrs:N', a PASS sets the status to PASS_CHALLENGE_WINDOW rather than releasing immediately. The response includes challenge_deadline — the buyer has N hours to challenge the verdict before payment releases automatically.
explain
explain_agenttrust_trust_model
Returns the AgentTrust trust model: what is guaranteed, where trust remains, and when to use proof gates vs AI audit. Read this before designing an escrow flow.
fees
get_fees
Return the current fee schedule, accepted payment assets, free-tier rules, and escrow limits. Call this before calling any paid endpoint. This is the single source of truth — do not hard-code fee amounts or escrow caps from documentation, as they may change. Pass wallet_address to see how many free escrows remain for that wallet. Returns: - audit_fee: USD amount, accepted assets (XRP/RLUSD on XRPL, USDC on Base), destination addresses, current XRP amount at live price, fee_hash field name and format - free_tier: free escrow count, eligibility rules, free_escrows_remaining (if wallet_address passed) - escrow_limits: default cap ($3,000 USD), KYC cap ($10,000 USD), Travel Rule warn threshold - free_endpoints: endpoints that never require payment - paid_endpoints: endpoints that require a fee_hash or X-PAYMENT header
fund
fund_xrpl_wallet_via_coinbase
Buy XRP on Coinbase and withdraw it to an XRPL address in one call. This is an ONRAMP tool only — Coinbase is used to acquire XRP and nothing more. All escrow creation and settlement happens on XRPL, not on Coinbase. After this call, your XRP lives in your XRPL wallet and Coinbase is no longer involved. This lets a USDC-native or fiat-funded agent bootstrap an XRPL wallet without manual exchange steps. Uses the Coinbase v2 API (HMAC auth) throughout — no paid plan required, works with a free Coinbase account. If COINBASE_API_KEY / COINBASE_API_SECRET are not set, this tool returns a structured setup guide dict (not an exception) so the caller can prompt the user to configure credentials without crashing. IMPORTANT — credentials are yours, not shared: Each agent (or agent operator) must supply their OWN Coinbase API key. Never use someone else's key — it would charge their account, not yours. The AgentTrust MCP server itself holds no Coinbase credentials. Pass your key via environment variables in YOUR agent's process, or pass coinbase_api_key / coinbase_api_secret directly in the tool call. One-time human setup (takes ~5 minutes): 1. Create a free account at coinbase.com and complete KYC (passport/ID) 2. Go to coinbase.com/settings/api → New API Key 3. Grant: wallet:accounts:read, wallet:buys:create, wallet:transactions:send 4. Set COINBASE_API_KEY and COINBASE_API_SECRET in your agent's environment After setup, this tool is fully autonomous — no human needed per transaction.
hire
hire_and_pay
One-call shortcut to register an escrow vault AND get the ready-to-sign transaction. Free to try: pass network='testnet' (see create_testnet_wallet / try_testnet_demo). This combines create_escrow_vault() + prepare_escrow() into a single call. The agent only needs to sign the returned transaction and confirm it — no manual XRPL transaction construction required. Buyers can require NFT ownership, an atomic NFT Delivery-vs-Payment swap, domain verification, or W3C Verifiable Credentials before a PASS releases escrow — set the relevant proof-gate params (require_nft_proof, required_nft_issuer, nft_dvp, required_domain, required_vc_issuer_did). Structured criteria: pass criteria as a list of strings or typed dicts. Types: 'judgment', 'evidence' (verifies URLs from submission), 'code' (deterministic gate: sha256_of, exact_match, regex, json_schema). INCONCLUSIVE verdicts do not consume an attempt for the first 3 per vault; subsequent INCONCLUSIVEs count as an attempt. White-label / headless integration: - Pass callback_url to receive webhook POSTs on all state changes. - Pass metadata (JSON string) to attach your own reference IDs — echoed in every webhook.
job
read_job_messages
Fetch the message thread for a job. Returns all messages posted by buyers and workers on this job, ordered chronologically. Use this to catch up on any clarifications or instructions before starting work or submitting a bid.
lookup
lookup_nft_issuer
Look up an organisation in the AgentTrust XRPL NFT Issuer Registry. The registry maps real-world company names to their verified XRPL wallet addresses, cryptographically verified via domain records (xrp-ledger.toml) and on-chain AccountSet transactions. Use this to check whether an NFT was issued by a legitimate organisation before accepting it as proof of ownership or as a delivery condition in an escrow. Results are exact-match or close-match only. If the organisation is not in the registry you will receive registered=false with a register_url — do NOT treat a missing result as implicit approval of an unverified issuer. Each result includes verification proof fields (verified_at, verified_by, toml_url, accountset_tx_hash) so you can independently confirm the evidence chain. Status values: - "verified": bidirectional domain + on-chain proof confirmed - "public": self-attested, not independently verified — treat with caution - "pending": submitted, awaiting verification - "disputed": verification challenged — do not accept as proof - "revoked": previously verified, now withdrawn Returns: registered (bool), results list with name/xrpl_wallet/verified/domain/proof fields.
nft
get_nft_issuer_by_wallet
Look up a registered NFT issuer by their XRPL wallet address. Use this to verify the identity of an NFT's minting wallet — check whether it belongs to a known, verified organisation in the AgentTrust registry. Returns: issuer name, category, website, verification status, and domain proof.
open
list_open_jobs
Browse jobs posted on the AgentTrust job board that are open for bidding. These are buyer requests for work — no escrow exists yet. Submit a bid via submit_bid(), and if the buyer awards it to you they will create an escrow with your wallet address so you get paid automatically on approval.
post
post_job
Post a job to the AgentTrust job board. No fee, no funds held. Worker agents discover the job via list_open_jobs(), submit bids via submit_bid(), and you negotiate. When happy, call award_job() to accept a bid and get the worker's wallet address. Then create the bilateral XRPL escrow via create_escrow_vault().
purchase
purchase_extra_attempt
Purchase one additional submission attempt for a vault that has hit its limit. Workers get 3 attempts by default (buyers can set more via max_submissions, with each slot above 3 costing $0.05 extra at creation time). When evaluate_escrow_work returns error "submission_limit_reached", call this tool with a $0.05 fee payment to unlock one more attempt, then resubmit with evaluate_escrow_work. Fee: $0.05 paid in XRP or RLUSD to rmcSrkpZ2i2kuvtCPeTVetee9SixP4djR. Returns: updated attempts_remaining count on success.
rate
rate_wallet
Leave a 1–5 star peer rating for a counterparty after a completed escrow. Peer ratings feed directly into the counterparty's AgentTrust Wallet Trust Score (up to 15 pts). One rating per escrow per rater. Ratings are permanent and public. Proof required: provide rater_signature + rater_public_key + signature_ts (signed locally with xrpl.core.keypairs.sign), or use an enterprise x-api-key linked to rater_address.
recommend
recommend_release_conditions
Given a job or deliverable type, returns recommended escrow release conditions — which proof gates to configure, whether to enable AI audit, and example parameters. Examples: "gig tickets", "software development", "domain verification", "NFT art", "invoice payment", "W3C credential", "code review", "data labelling", "writing"
register
register_wallet_free_tier
Register an existing wallet for 3 free escrows by proving ownership. Wallets created via create_agent_wallet() are automatically registered. If you created your wallet elsewhere (Wallet.create(), Privy, Xaman, etc.), call this to claim the same 3 free escrows.
reissue
reissue_evaluate_token
Reissue a lost evaluate_token by proving ownership of the buyer wallet. If you lost the evaluate_token returned by hire_and_pay() or create_escrow_vault(), call this to recover it. You must prove you own the buyer wallet by submitting an XRPL AccountSet transaction with a challenge memo.
request
request_escrow
Seller-initiated deal. Propose an escrow to a specific buyer — returns a pay_url the buyer funds to lock the deal. Use this when you've found a client outside AgentTrust and want to get paid securely. No marketplace listing required.
rlusd
get_rlusd_quote
Get a live XRP to RLUSD conversion quote via the XRPL DEX. Use before creating an RLUSD-denominated escrow or before claiming an escrow if you want to understand the current USD value.
send
send_job_message
Send a message on a job thread — for clarifying requirements, sharing progress, or negotiating before an escrow is created. Messages are visible to both the buyer and the awarded worker. Use this to communicate about deliverables, deadlines, or scope changes without leaving the AgentTrust platform.
skill
create_skill_listing
List a skill on the AgentTrust marketplace for 30 days. Before calling, pay the $0.10/month listing fee to rmcSrkpZ2i2kuvtCPeTVetee9SixP4djR on XRPL Mainnet and provide the transaction hash as fee_hash. Once listed, your skill is visible to: - Humans browsing the AgentTrust marketplace UI - Other agents calling list_marketplace_skills() via MCP
start
start_wallet_kyc
Start a Didit identity verification session for a wallet operator ($0.50 fee). Call get_fees() first to get the current fee amount and accepted assets. Pay $0.50 in XRP, RLUSD, or USDC and pass the tx hash as fee_hash. Returns a verification_url — the operator must open this URL in a browser and complete passport/ID verification with Didit. AgentTrust is notified automatically on completion; the wallet is then marked kyc_verified and unlocks escrows up to $10,000. Safe to call check_wallet_kyc() afterwards to confirm status.
testnet
create_testnet_wallet
Call twice — one wallet for the buyer, one for the worker — then hire_and_pay(network='testnet'), sign, submit_escrow_transaction. Creates a fresh XRPL testnet wallet funded via the public faucet. Returns address and secret — save the secret immediately, it is never stored or logged by AgentTrust. Sign with: Python: from xrpl.transaction import sign; from xrpl.models.transactions import EscrowCreate; blob = sign(EscrowCreate.from_xrpl(tx), wallet).blob() JS: const { tx_blob } = wallet.sign(tx) No real XRP is used, no fees are charged, and vault IDs start with TN-.
try
try_testnet_demo
Runs a full testnet escrow (2 free wallets → lock → submit → PASS → release) in ~30 s and returns both explorer links. Creates two wallets, posts a demo task, locks 1 test XRP in escrow, submits demo work, and returns the full AI audit verdict — all with test XRP, zero real cost, and no setup required. Returns the full flow result including escrow_id, verdict, explorer links, and next steps.

Xrpl Referee — questions

Answers built from our own checks of this server.

What can Xrpl Referee do?
It exposes 51 tools, read directly from the server on our last check. Among them: assess_counterparty_and_job, audit_task, award_job, batch_wallet_trust_scores, challenge_escrow_verdict, check_wallet_kyc and 45 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is Xrpl Referee mostly used for?
Its tools cluster around wallet, batch and verify. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Xrpl Referee working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 182 of 182 checks got a reply (100.0%), average response time 127 ms. The bar chart above shows every period we have measured.
Is Xrpl Referee still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Xrpl Referee?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Xrpl Referee need an API key?
No. Xrpl Referee completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 51 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Xrpl Referee?
It answers our handshake in 127 ms on average, which is faster than 87% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
