Anlyon alternative
3 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.

Changes things 3Claude Code: ask
build_swap_txFree.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Free. Returns an UNSIGNED base64 transaction for the taker wallet to sign. Advan never signs and never holds keys. Default (selfBroadcast false) keeps JupiterZ routes, which need Jupiter POST /swap/v2/execute to add the market-maker co-signature. Pass selfBroadcast true to exclude jupiterz so the taker can broadcast the signed transaction.
token_riskPaid token risk report ($0.02 USDC via x402 exact on solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Paid token risk report ($0.02 USDC via x402 exact on solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp). Combines RPC mint/freeze authority, Jupiter Tokens V2, and RugCheck. Ordinary MCP clients that cannot pay receive a payment-required error.
wallet_portfolioPaid wallet portfolio ($0.02 USDC via x402 exact).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Paid wallet portfolio ($0.02 USDC via x402 exact). SOL plus SPL Token and Token-2022 balances, priced with Jupiter Price V3.
Only reads 1Show 1 read-only tool
get_quoteFree Jupiter Swap API V2 quote (GET /swap/v2/order, no taker).No findings
Why it is in this group
- The name "get_quote" says "get": a word for reading.
Description, as the server wrote it Free Jupiter Swap API V2 quote (GET /swap/v2/order, no taker). Returns amounts, route, slippage, and referral fee fields. Does not return a transaction.
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.
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.
Install

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [
"mcp__advan__get_quote"
],
"ask": [
"mcp__advan__build_swap_tx",
"mcp__advan__token_risk",
"mcp__advan__wallet_portfolio"
],
"deny": []
}
}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 advan. Review it before you use it.
Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
