Can't be undone 2Sends, pays, publishes or merges: once done, it cannot be taken back.Claude Code: ask

check_paymentAsk Fresh SEM to look for the exact official-USDC payment from the quoted sending wallet and return the verified order state.Reads text others writeNo findings
Why it is in this group
- The name "check_payment" says "payment": a word that usually means money moves, which cannot be taken back.
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
Ask Fresh SEM to look for the exact official-USDC payment from the quoted sending wallet and return the verified order state. This never signs or broadcasts.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: true
- openWorldHint: true
submit_payment_proofSubmit a transaction hash as a lookup aid.Reads text others writeNo findings
Why it is in this group
- The name "submit_payment_proof" says "submit": a word for a change.
- The name "submit_payment_proof" also says "payment": a word that usually means money moves, which cannot be taken back.
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
Submit a transaction hash as a lookup aid. Fresh SEM independently verifies chain, official token, sender, recipient, amount, quote time, success, finality, and single use before fulfilment.

- 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
Create one pending order and return exact USDC payment coordinates. This does not connect a wallet, sign, broadcast, or move funds. Keep the access token secret and obtain the wallet owner's approval before payment.

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 write5: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; check_payment
check_service_health
create_quote
get_order_status
submit_payment_proof
Can send data out1: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; create_quote

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Install

Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http agent-backlinks https://freshsem.com/scripts/agent_backlinks_mcp.php

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__agent-backlinks__describe_backlink_service",
      "mcp__agent-backlinks__get_payment_requirements",
      "mcp__agent-backlinks__check_service_health"
    ],
    "ask": [
      "mcp__agent-backlinks__create_quote",
      "mcp__agent-backlinks__check_payment",

      "mcp__agent-backlinks__get_order_status"
    ],
    "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 agent-backlinks. Review it before you use it.

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.
