Anlyon alternative

4 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
- 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.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it
Backtest any crypto strategy on 399 Coinbase coins, bias-free. Breakout, momentum, dip-buy or MA trend rules on Coinbase daily data with fees, slippage, H1/H2 split, luck flag and survivorship-bias-free universe. Price: $0.05 USDC per call (x402, Base mainnet). Free pre-check: validate_backtest.

Description, as the server wrote it
Daily crypto market regime: BTC/ETH trend, breadth, breakout watchlist. BTC/ETH vs 20/50-day MAs, market breadth (% of point-in-time top-N above 20DMA), coins nearest a 20-day breakout, and the R1 breakout strategy's gate and entry signals. Completed UTC daily closes only. Price: $0.01 USDC per call (x402, Base mainnet).

Find robust strategy params, not lucky ones: tests up to 50 combos of a backtest strategy; ranks by worst-half (H1/H2) return with neighbourhood smoothing, flags overfitting, and recommends the most robust parameters rather than the best-fit ones.

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 outbound.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write11: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; backtest
get_schema
health
market_signals
optimize_strategy
token_check
universe_snapshot
validate_backtest
validate_optimize
validate_token_check
validate_universe
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.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

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 crypto-quant. Review it before you use it.
