Anlyon alternative

15 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.

Description, as the server wrote it
Recent ERC20 transfers for a token or wallet. Recent ERC20 Transfer events (decoded: from, to, amount with decimals, symbol, tx hash, block) for a token contract, a wallet, or both, over the last ~2,000 blocks on Base, Arbitrum or Optimism (~500 on Ethereum).

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 write19: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; ai_extract

Can send data out2: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; ai_extract

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