Allow, ask, or veto — a policy decision point your agent consults before signing any payment

Anlyon alternative
5 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.

Deletes or cancels 1Claude Code: deny
revoke_policy[USER ONLY] Revoke a policy chain (takes effect immediately; subsequent payments default to DENY).No findings
Why it is in this group
- The name "revoke_policy" says "revoke": a word for removing or ending something.
Description, as the server wrote it [USER ONLY] Revoke a policy chain (takes effect immediately; subsequent payments default to DENY). Must carry the user's wallet signature over the revocation statement.
Can't be undone 1Claude Code: ask
evaluate_paymentEvaluate a payment intent.Can send data outNo findings
Why it is in this group
- The name "evaluate_payment" says "evaluate": a word for a change.
- The name "evaluate_payment" also says "payment": a word that usually means money moves, which cannot be taken back.
- The input addresses people (input.recipient): what it sends cannot be taken back.
What it can reach
- outboundThe input takes a destination (input.recipient): what the tool writes goes there.
Description, as the server wrote it Evaluate a payment intent. MUST be called before executing any payment. ALLOW = you may pay; DENY = you must abandon; ASK = a challenge is returned — relay the reason to the user, then retry with approval_token once the user signs. An optional mandate parameter carries a user-issued single-task authorization.
Changes things 3Claude Code: ask
render_templateRender a natural-language rule from a template + parameters (then compile, sign & publish)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 Render a natural-language rule from a template + parameters (then compile, sign & publish)
request_policy_change[For agents] Ask the user for a policy/budget change (e.g.No findings
Why it is in this group

Description, as the server wrote it [For agents] Ask the user for a policy/budget change (e.g. 'raise daily budget from 50 to 80'). The request is queued for user approval; the user signs and publishes a new policy version. Agents can NEVER change policy directly.
set_policy[USER ONLY] Submit a new policy version.No findings
Why it is in this group
- The name "set_policy" says "set": a word for a change.
Description, as the server wrote it [USER ONLY] Submit a new policy version. Must carry the user's wallet EIP-191 signature over the policy document; accepted only after signature + version-chain checks pass. Agents MUST NOT call this tool.

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.
- 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 out1
- 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
Pinned to version 0.1.2. Values in angle brackets are yours to fill in.

Claude Code permissions
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 boundra. Review it before you use it.

Keep the decision: fail CI when the tools change, follow every change, or show a badge.
