6 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.

  What this check looks for
Description, as the server wrote it
Live on-chain token & smart contract rug-pull / honeypot shield for Base, Ethereum, and Solana. Inspects live EVM bytecode (blacklist selectors, mutable tax fees, pause toggles, unverified proxies) and Solana SPL / Token-2022 mint accounts (active mint authority, freeze authority, Permanent Delegate wallet seizure, Transfer Hook honeypots) plus live DexScreener liquidity and 24h buy/sell ratios. Price: $0.05 Base USDC or 0.00035 SOL.
create_session_depositActivate a prepaid session voucher (0.006 SOL or 0.85 Base USDC for 10 operations).No findings
Why it is in this group
- The name "create_session_deposit" says "create": a word for a change.
Description, as the server wrote it
Activate a prepaid session voucher (0.006 SOL or 0.85 Base USDC for 10 operations). Eliminates per-request payment prompts and RPC latency in autonomous agent loops.

  What this check looks for
Description, as the server wrote it
Deterministic code security scanner for AI agents. Analyzes Python, JavaScript, and TypeScript code for 45+ vulnerability patterns (injection, hardcoded secrets, wallet key exfiltration, SSRF, infinite x402 loops, unsimulated Solana transactions). Returns deterministic AST patches, unified diffs, and execution verdicts (PASS, WARN, BLOCK). Price: $0.10 Base USDC or 0.0007 SOL.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
What it can reach
- untrusted-inputThe name "scrape_url" says "scrape": it reads web pages, which anyone can write.
- outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

  What this check looks for
Description, as the server wrote it
Anti-bot web access & scraper oracle for AI agents. Fetches web pages with stealth headers to bypass Cloudflare Turnstile, WAFs, and anti-bot challenges. Purifies HTML by removing scripts, stylesheets, tracking pixels, ads, and navigation boilerplate, returning clean, token-efficient Markdown ready for LLM consumption with cryptographic oracle attestation. Price: $0.02 Base USDC or 0.00015 SOL.

  What this check looks for
Description, as the server wrote it
Pre-flight transaction & drainer shield for AI agents. Simulates and inspects EVM (Base/Ethereum) and Solana transactions before signing or broadcasting. Detects unlimited approvals, known drainers, honeypots, MEV sandwich exposure (min_output=0), and unauthorized Solana authority takeovers. Returns execution verdict (ALLOW, WARN, BLOCK) and cryptographic oracle attestation. Price: $0.05 Base USDC or 0.00035 SOL.

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 write1: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; scrape_url
Can send data out1: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; scrape_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.

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

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 scanpay. Review it before you use it.
