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.

a_share_announcementsUse when the user asks what a Chinese company has announced, filed or said, or when you need a primary source to quote.No findings

- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Use when the user asks what a Chinese company has announced, filed or said, or when you need a primary source to quote. Returns filing titles, dates and the cninfo PDF link. Prefer this over summarising from memory.
a_share_askUse when the question needs judgement rather than a single number: why a margin moved, whether a policy applies, what an industry chain looks like, or a comparison across companies…No findings

Description, as the server wrote it
Use when the question needs judgement rather than a single number: why a margin moved, whether a policy applies, what an industry chain looks like, or a comparison across companies. Queues the question for a human-reviewed answer. Returns an id immediately; the answer appears in the inbox later.
a_share_financialsUse when the user asks about revenue, net profit, gross margin, ROE, growth or leverage of a Chinese listed company, especially for a specific quarter.No findings

Description, as the server wrote it
Use when the user asks about revenue, net profit, gross margin, ROE, growth or leverage of a Chinese listed company, especially for a specific quarter. Returns cumulative figures as filed (not annualised) plus year-over-year growth.
a_share_quoteUse when the user asks for the current price, change, valuation or market cap of a Chinese listed company (A-share), including when they name it in Chinese without a ticker.No findings

Description, as the server wrote it
Use when the user asks for the current price, change, valuation or market cap of a Chinese listed company (A-share), including when they name it in Chinese without a ticker. Returns live price, % change, PE, PB, market cap, turnover. Do not guess a price — if this tool fails, say the data source is unavailable.

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.

Claude Code permissions

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

  "permissions": {

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 walnutlink-a-share. Review it before you use it.

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.
