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.

    Why it is in this group

    • The name "get_receipt" says "get": a word for reading.
    • The server marks it as not read-only (readOnlyHint: false).

      What this check looks for
    Description, as the server wrote it
    Privately refresh an order against Stripe and retrieve its receipt/digital fulfillment. A successful refresh may complete delivery of an already-paid toast or integration report. No new order, charge or future permission is created.

    Annotations the server declares

    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: true
  • place_orderExplicitly order one item.Reads text others writeCan send data outNo findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    • outboundThe input takes a URL (input.target_url): a request to a URL can carry data to whoever runs it.
    Description, as the server wrote it
    Explicitly order one item. Totals: beer 0, sponsor round 300, report 500 EUR cents. Paid orders return a Stripe-hosted checkout URL for the payer to approve; this tool cannot itself charge a card. Use public_credit only for explicit opt-in sponsor display. A report requires your public HTTPS Agent Card URL. Public buyer identity is self-declared. Never provide card details, secret keys, or private endpoint URLs. Save the private receipt token.

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.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write2
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.

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.

All changes to this server

Install

Pinned to version 1.1.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http barman-ai-agent https://barman-ai-agent.onrender.com/mcp
claude mcp add --transport http barman-ai-agent https://barman-ai-agent.onrender.com/mcp

Run in a terminal.

Claude Code permissions

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

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__barman-ai-agent__get_catalog"
    ],
    "ask": [
      "mcp__barman-ai-agent__place_order",
      "mcp__barman-ai-agent__get_receipt"
    ],
    "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 barman-ai-agent. Review it before you use it.

Capability tags behind 2 rules
  • mcp__barman-ai-agent__place_order untrusted-input, outbound
  • mcp__barman-ai-agent__get_receipt untrusted-input
