  What this check looks for
Description, as the server wrote it
WRITE (spends credits): look up ONE phone number's carrier data (country, network, MCC/MNC, ported, reachable, mobile or fixed). Each lookup is billed to the D7 account's credit balance (the cost is returned by d7_get_lookup_report as number_lookup_cost) and the account must have lookup routing enabled. It does not message the number. D7 REST: POST /hlr/v1/lookup.

- readOnlyHint: false
- destructiveHint: true
- idempotentHint: false
- openWorldHint: true

Description, as the server wrote it
WRITE (sends real text messages and spends credits): send ONE text message to 1-10 recipients (never a list or campaign). Each recipient costs the per-country price for every message part (about 160 GSM characters or 70 unicode characters per part; see d7_get_sms_pricing), taken from the D7 credit balance, and a sent SMS cannot be recalled. Free trial accounts may only use D7's demo sender id; other sender ids must be registered with D7. Send only messages the recipients expect, as unsolicited SMS violates D7's terms. Returns a request_id for d7_get_message_status. D7 REST: POST /messages/v1/send.

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.

3 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 1 outbound tool breaks every one.

Reads private data1: Reads files, mail, messages, databases, secrets, calendars or repositories.; d7_get_message_status
Reads text others write3: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; d7_get_message_status
d7_lookup_number
d7_send_sms
Can send data out1: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; d7_send_sms

deny to break every path

{
  "permissions": {
    "deny": [
      "mcp__d7-networks__d7_send_sms"
    ]
  }
}

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 1.3.4. Values in angle brackets are yours to fill in.

claude mcp add --transport http d7-networks https://d7-networks.usefulapi.io/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__d7-networks__d7_get_balance",
      "mcp__d7-networks__d7_get_sms_pricing",
      "mcp__d7-networks__d7_get_message_status",

  }
}

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 d7-networks. Review it before you use it.

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.
