## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: health (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_web (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); scrape_url (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,745 tokens to load every tool

### stability: 100 (weight 15)

- pass `stability.changes`: 4 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-16 `lookup_wallet` changed (description)
  - before: Universal address lookup — any address, any chain, auto-detected. Params: address (EVM 0x address or XRPL classic r-address, required); chain (optional EVM history hint: base default, or ethereum). Detects EVM vs XRPL from the format. Returns one normalized envelope: { address, chain, chain_detected, exists, risk_score, risk_level, verdict, flags, entity, name }. Free. For a fast first-pass check on a counterparty wallet.
  - after: Address lookup for Ethereum and Base 0x addresses and XRPL r-addresses, auto-detected. Params: address (EVM 0x address or XRPL classic r-address, required); chain (optional EVM history hint: base default, or ethereum). Detects EVM vs XRPL from the format. Returns one normalized envelope: { address, chain, chain_detected, exists, risk_score, risk_level, verdict, flags, entity, name }. Free. For a fast first-pass check on a counterparty wallet.
- 2026-10-16 `lending_grade` changed (description)
  - before: A-F risk grade for one XRP Ledger lending vault or loan broker, from on-ledger data only (size, utilization, first-loss cover ratio, late/impaired/defaulted loans, unrealized loss, realized yield), with every rule that moved the grade. Not a credit rating. This is a PAID x402 call: $0.02 USDC on Base at GET /api/lending/grade. This tool returns the payment resource to call; it does not compute the grade. Until XRPL lending is enabled on mainnet it says so instead. Params: id (64-hex Vault or LoanBroker ID, required); type (vault | broker, optional).
  - after: A-F risk grade for one XRP Ledger lending vault or loan broker, from on-ledger data only (size, utilization, first-loss cover ratio, late/impaired/defaulted loans, unrealized loss, realized yield), with every rule that moved the grade. Not a credit rating. This is a PAID x402 call: $0.02 USDC on Base at GET /api/lending/grade. This tool returns the payment resource to call; it does not compute the grade. NOT LIVE YET: it goes live when XRPL lending (the LendingProtocol and SingleAssetVault amendments) is enabled on mainnet. Until then this tool returns available:false and GET /api/lending/grade returns 503 with no charge. Params: id (64-hex Vault or LoanBroker ID, required); type (vault | broker, optional).
- 2026-10-16 `yield_grade` added
  - A-F risk grade for one way to earn on XRP or RLUSD, from the XRP Yield Desk (xrplhub.io/yield): XRPL AMM pools, Doppler vaults, Firelight stXRP and other Flare FXRP products, RLUSD and XRP DeFi pools, and exchange earn programs. Returns the rate, size, lockup and withdrawal terms, who holds the keys, chain, age, audits, the data source with its timestamp, and every rule that moved the grade. General information, not advice; the products graded pay nothing. This is a PAID x402 call: $0.02 USDC on Base at GET /api/yield/grade. This tool returns the payment resource to call; it does not compute the grade. Find ids for free at https://www.xrplhub.io/api/yield/options. Params: id (option id, required).
- 2026-10-16 `lending_grade` added
  - A-F risk grade for one XRP Ledger lending vault or loan broker, from on-ledger data only (size, utilization, first-loss cover ratio, late/impaired/defaulted loans, unrealized loss, realized yield), with every rule that moved the grade. Not a credit rating. This is a PAID x402 call: $0.02 USDC on Base at GET /api/lending/grade. This tool returns the payment resource to call; it does not compute the grade. Until XRPL lending is enabled on mainnet it says so instead. Params: id (64-hex Vault or LoanBroker ID, required); type (vault | broker, optional).

## Packages

_none_

## Tools (9)

- `caller_id`: Should this wallet be answered? For wallet messaging (XMTP, Push), which has no spam filter. Params: address (0x EVM address, required); chain (base default, or ethereum). Composes entity attribution + risk score + on-chain history + forward-verified name into ANSWER | SCREEN | BLOCK with reasons[] and a confidence flag. BLOCK on sanctioned/drainer/phishing/scam/mixer or risk verdict BLOCK; SCREEN is the default for unknown addresses. Free.
- `check_entity`: Entity attribution — what IS this address, not who owns it. Params: address (0x EVM address, required); chain (base default, or ethereum). Returns { address, chain, is_known, label, category }. category is one of sanctioned, mixer, exchange, bridge, dex_router, scam, drainer, phishing, flagged, token_contract, protocol, unknown. "sanctioned" is set only when the address is on the OFAC SDN list (the same source /api/risk uses); a non-OFAC blocklist hit is "flagged". Sourced from OFAC, ScamSniffer, MEW, eth-labels and curated Base/Tornado sets. Never guesses. Free.
- `health`: Service health check. No parameters. Returns { ok, service, time, upstream } — confirms the uxus.finance API is reachable. Free.
- `lending_grade`: A-F risk grade for one XRP Ledger lending vault or loan broker, from on-ledger data only (size, utilization, first-loss cover ratio, late/impaired/defaulted loans, unrealized loss, realized yield), with every rule that moved the grade. Not a credit rating. This is a PAID x402 call: $0.02 USDC on Base at GET /api/lending/grade. This tool returns the payment resource to call; it does not compute the grade. NOT LIVE YET: it goes live when XRPL lending (the LendingProtocol and SingleAssetVault amendments) is enabled on mainnet. Until then this tool returns available:false and GET /api/lending/grade returns 503 with no charge. Params: id (64-hex Vault or LoanBroker ID, required); type (vault | broker, optional).
- `lookup_wallet`: Address lookup for Ethereum and Base 0x addresses and XRPL r-addresses, auto-detected. Params: address (EVM 0x address or XRPL classic r-address, required); chain (optional EVM history hint: base default, or ethereum). Detects EVM vs XRPL from the format. Returns one normalized envelope: { address, chain, chain_detected, exists, risk_score, risk_level, verdict, flags, entity, name }. Free. For a fast first-pass check on a counterparty wallet.
- `resolve_name`: Bidirectional name <-> address resolution for ENS (name.eth) and Basenames (name.base.eth). Param: q (an ENS/Basename name, an EVM 0x address, or an XRPL r-address, required). Auto-detects direction. Reverse records are forward-verified against the address to stop name spoofing. Returns { query, kind, namespace, chain, resolved, address, name, sources }. XRPL .xrp names are detected but resolved:false (no canonical registry). Free.
- `scrape_url`: Any web page as clean, LLM-ready markdown, text or html. This is a PAID x402 call: $0.01 USDC on Base at GET /api/scrape. This tool returns the payment resource to call; it does not fetch the page. Params: url (absolute http/https URL, required); format (markdown | text | html, default markdown); max_chars (integer, default 40000, max 120000).
- `search_web`: Live web search: ranked results plus Google's answer box, knowledge graph, people-also-ask and related searches when the Google-backed provider answers. This is a PAID x402 call: $0.01 USDC on Base at GET /api/search. This tool returns the payment resource to call; it does not run the search. Params: query (string, required); count (integer 1-20, default 10); country/language/page/device (optional).
- `yield_grade`: A-F risk grade for one way to earn on XRP or RLUSD, from the XRP Yield Desk (xrplhub.io/yield): XRPL AMM pools, Doppler vaults, Firelight stXRP and other Flare FXRP products, RLUSD and XRP DeFi pools, and exchange earn programs. Returns the rate, size, lockup and withdrawal terms, who holds the keys, chain, age, audits, the data source with its timestamp, and every rule that moved the grade. General information, not advice; the products graded pay nothing. This is a PAID x402 call: $0.02 USDC on Base at GET /api/yield/grade. This tool returns the payment resource to call; it does not compute the grade. Find ids for free at https://www.xrplhub.io/api/yield/options. Params: id (option id, required).
