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.

Can't be undone 1Claude Code: ask
agent_payment_checkBefore an AI agent pays, checks the proposed payment against the person's mandate (who allowed it, limits per payment and per period, allowed shops and UPI IDs, end date) and again…1 finding
Why it is in this group
- The name "agent_payment_check" says "payment": a word that usually means money moves, which cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Findings
- Warn
The server marks "agent_payment_check" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".
What this check looks forMatched text
annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The name "agent_payment_check" says "payment": a word that usually means money moves, which cannot be taken back.
Description, as the server wrote it Before an AI agent pays, checks the proposed payment against the person's mandate (who allowed it, limits per payment and per period, allowed shops and UPI IDs, end date) and against what the person actually asked for (items, quantities, budget, shop). It works the total out again from the cart lines, and flags lookalike payees, extra items, too much quantity, going over a limit and repeat payments. Returns every check and a receipt signed by Nityaflow. It never pays, holds or moves money: a licensed bank or payment app does that, only after a person approves.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: false
- idempotentHint: true
Changes things 2Claude Code: ask
gst_credit_matchIndia GST input tax credit check.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.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it India GST input tax credit check. Matches the supplier invoices in GSTR-2B against the purchase register from the books (Tally, Zoho Books, Busy, QuickBooks or any list) and sorts every invoice into: matched, amount mismatch, possible match (invoice number written differently), in books but not in GSTR-2B (credit at risk), in GSTR-2B but not in books. A separate checker re-derives the totals, and the result comes with a receipt signed by Nityaflow. Invoices are processed in memory and not stored. It never files or accepts anything on the GST portal.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: false
- idempotentHint: true

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.
The server marks "agent_payment_check" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [],
"ask": [

"mcp__gst-credit-match__agent_payment_check"
],
"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 gst-credit-match. 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.
