## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__prax-data-services__analyze_transaction` `mcp__prax-data-services__fetch` `mcp__prax-data-services__get_alerts` `mcp__prax-data-services__screen_entity` `mcp__prax-data-services__screen_transfer` `mcp__prax-data-services__screen_transfers_batch` `mcp__prax-data-services__screen_wallet` `mcp__prax-data-services__screen_wallets_batch` `mcp__prax-data-services__search` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__prax-data-services__screen_transfer` |

## Findings

- **warn** Annotations that disagree with the tool in `screen_transfer` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "screen_transfer" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "screen_transfer" says "transfer": a word for a change that another call does not undo.
```

- **warn** Annotations that disagree with the tool in `screen_transfers_batch` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "screen_transfers_batch" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "screen_transfers_batch" says "transfer": a word for a change that another call does not undo.
```


## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `screen_transfer`

- The name "screen_transfer" says "transfer": a word for a change that another call does not undo.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `screen_transfers_batch`

- The name "screen_transfers_batch" says "transfer": a word for a change that another call does not undo.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `screen_entity`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `screen_wallet`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `screen_wallets_batch`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `analyze_transaction`

- The name "analyze_transaction" says "analyze": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `fetch`

- The name "fetch" says "fetch": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

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

### `get_alerts`

- The name "get_alerts" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `search`

- The name "search" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Claude Code permissions
