Anlyon alternative

5 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Why it is in this group
- 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.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe input takes a destination (input.to): what the tool writes goes there.
Findings
- Warn
  The server marks "screen_transfer" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

Description, as the server wrote it
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.

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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

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

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write9: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; analyze_transaction

screen_entity
screen_transfer
screen_transfers_batch
screen_wallet
screen_wallets_batch

Can send data out1: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; screen_transfer

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as prax-data-services. Review it before you use it.
