11 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 Was a trade well executed? Give the token sold and bought, the amount sold, the amount received, the time (ISO such as 2026-10-27T18:05:00Z, or unix seconds) and optionally the venue. The trade is priced again on every venue from the pool reserves and order books read at the five-minute ticks either side of it (archive since 27 Oct 2026), by the same code as quote(), after network fees. Returns the venue that returned the most, how far the trade fell short of it in basis points (at the reading least favourable to that), and with venue given, how much of the gap was the choice of venue and how much the fill itself. Nothing is executed or stored.

Description, as the server wrote it What selling a token for dollars (USDCx) nets on Canton, as a share of its value at our price: a ladder from $1K to $1M per venue and at the best one (with across_venues when selling the token for CC on one venue and that CC for dollars on another keeps more), the largest sale each venue (and all of them together) takes within 1%, 2% and 5%, what limited each (the cost, or the end of a venue's visible order book), and the worst share at $10K and $50K since the record began. For lending, vault and risk tools: what collateral sells for on Canton, not only what it is quoted at. With amount_usd, also that exact sale priced now on every venue (as quote() would).

Description, as the server wrote it Best execution for selling `amount` of token `sell` (or `amount_usd` worth) for token `buy`, on every venue that can make the trade on its own markets in one or two swaps: an AMM pool (Cantex, Tradecraft, OneSwap, Pool Party), an order book (Temple, Rocky), or two of them in a row on the same venue (Temple: CC to USDCx, then USDCx to CBTC; Pool Party: CC to USDC.B, then USDC.B to CBTC). The same comparison as the site's best execution, at any size. Pool fees, book fees and price impact are included; `after_network_fee` also takes off the venue's per-trade network fee on each swap (the fee table, with which fees are measured, documented or assumed, is in `network_fees`). A pool whose reserves have stood still while its price left the market is no market here (`not_trading`). A venue whose route takes an order book that shows more of a token than exists (a side larger than its registry's total supply) carries `book_shows_more_than_exists`: its price, not a size it can fill.

Description, as the server wrote it Buy-on-one-venue, sell-on-the-other round trips at their best size, after each venue's network fee: `cost_cc` per route, `swap_cost_cc` per venue (Cantex measured, OneSwap and Tradecraft documented, the rest assumed at 1.5 CC). A trip through an order book in dollars (via=usd) also pays the CC/USDCx leg of each pool side. `clears` is true when one nets at least $0.50.

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 or untrusted-input or outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out0
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
