## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1192 tokens (~132/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 75/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 26% of tool parameters carry a description.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "screen_transfer" implies "transfer" and declares readOnlyHint instead, contradicting what its own name says it does.
  - An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (9)

### `screen_wallet` (~133 tokens)

Screen wallet / contract

Wallet and smart-contract risk screening (KYT / AML): check any EVM address against Prax threat intelligence - OFAC and global sanctions, exploits, hacks, phishing, scams, drainers, mixers, malicious contracts, and first-hop exposure to them. Returns risk band, labels, roles, alerts naming it, counterparties and a plain-language story. Use before onboarding, paying or interacting with an address. Free plan. Set live=true for live on-chain screening too.

Input parameters:

- `address` (string, required)
- `chain` (string)
- `live` (boolean): also run live chain screening (slower)

### `analyze_transaction` (~79 tokens)

Analyze transaction

Transaction risk analysis: given an EVM transaction hash, returns status, value, counterparties and the risk of both sides (sanctions, exploit, phishing, scam exposure) with flags. Use for post-trade monitoring, incident triage and fraud investigation. Builder plan and above.

Input parameters:

- `chain` (string)
- `hash` (string, required)

### `screen_transfer` (~147 tokens)

Screen transfer (pre-sign)

Pre-signature transfer check (payment screening): is it safe to send `amount` of `asset` from `from` to `to`? Returns allow / review / block with reasons - sanctioned or flagged parties, malicious or scam token, look-alike address poisoning, first-time payee. Works before the transaction exists; no chain lookup needed. Use in wallet, custody, payment and treasury flows. Builder plan and above.

Input parameters:

- `amount` (number): in the asset's own units
- `asset` (string): 'native' or token contract address
- `chain` (string)
- `from` (string, required): sender address
- `to` (string, required): recipient address

### `screen_entity` (~122 tokens)

Sanctions screening

Sanctions screening for people, companies, vessels and crypto addresses: fuzzy name match (aliases, transliterations) or exact wallet / contract lookup against the OFAC SDN and other sanctions lists Prax tracks. Returns match / possible_match / no_match with hits (entity, type, programs, list, aliases, linked crypto addresses, score). Use for KYC / KYB onboarding and payment screening. Free plan.

Input parameters:

- `limit` (integer)
- `name` (string, required)
- `type` (string): optional: individual, entity, vessel, aircraft

### `screen_wallets_batch` (~72 tokens)

Screen wallets (batch)

Bulk wallet screening: screen_wallet for up to 50 addresses in one call - portfolio, customer-base or deposit-address sweeps. Returns per-address risk band and labels plus a summary. Builder plan and above; 10 credits per call.

Input parameters:

- `addresses` (array, required)
- `chain` (string)

### `screen_transfers_batch` (~75 tokens)

Screen transfers (batch)

Bulk transfer screening: screen_transfer for up to 50 transfers in one call (items of {from, to, amount, asset, chain}) - payout batches, payroll, exchange withdrawals. Returns a verdict per item and a summary. Builder plan and above; 10 credits per call.

Input parameters:

- `items` (array, required)

### `get_alerts` (~102 tokens)

Threat-intel alerts (24h)

Threat-intelligence alert feed: approved Prax alerts from the last 24 hours (new exploits, attacker wallets, malicious contracts, phishing campaigns, sanctions updates), newest first, same payload as the webhook feed. Use for SOC / compliance monitoring and watchlist updates. Business plan and above; 100 credits per pull.

Input parameters:

- `cursor` (string)
- `limit` (integer)
- `severity` (string)
- `since_hours` (integer)

### `search` (~194 tokens)

Search Prax intel

Search Prax threat intelligence in plain words (e.g. 'critical attacker wallets on base this week', 'phishing contracts created by 0x...'). Returns COUNTS of matching addresses (by band, chain, role) plus approved alerts from the last 24 h; address lists are not enumerable - look a specific address up with screen_wallet. Filters: chain (eth, base...), risk band (critical, high), role (attacker wallet, malicious contract, deployer, funding ancestry, clone), period (today, last 7 days, since 2026-10-01), free text (bytecode clone, phishing), 'created by 0x...', 'counterparties of 0x...'. An exact address or tx hash returns that record's id. Use fetch(id) for the full record. Business plan and above.

Input parameters:

- `limit` (integer)
- `query` (string, required)

### `fetch` (~51 tokens)

Fetch intel record

Fetch the full Prax intelligence record for an id returned by search (address:<chain>:<addr>, tx:<chain>:<hash>, alert:<id>). Business plan and above.

Input parameters:

- `id` (string, required)
