Anlyon alternative

2 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.

build_unsigned_tradeBuild a fresh Solana mainnet v0 transaction and quote for a Limitless bonding-curve buy/sell.Reads text others writeNo findings
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
Build a fresh Solana mainnet v0 transaction and quote for a Limitless bonding-curve buy/sell. Every signature is zero. The caller must independently validate, simulate, sign and broadcast. No keys accepted. Network fees and possible account/escrow rent are extra.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: false
- openWorldHint: true
submit_listingPrepare or dispatch supported listing requests through the website’s shared Get listed backend.Reads text others writeNo findings
Why it is in this group
- The name "submit_listing" says "submit": a word for a change.
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
Prepare or dispatch supported listing requests through the website’s shared Get listed backend. Requires proof from the token creator. Omit signature and issuedAt to get the exact message to sign locally, then repeat with both. Manual forms remain action_required; paid targets remain payment_required. No paid submission, wallet signing or blockchain transaction. A prepared packet is not provider acceptance.
Annotations the server declares
- readOnlyHint: false

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 write10: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; build_unsigned_trade
get_listing_status
get_portfolio
get_prices
get_token_detail
get_tokens
get_trade_quote
get_trending
list_listing_targets
submit_listing
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 limitless. Review it before you use it.
