    Why it is in this group

    • The name "soma_send" says "send": a word for sending, and what is sent cannot be taken back.
    • The input addresses people (input.to): what it sends cannot be taken back.

    What it can reach

    • outboundThe name "soma_send" says "send": it sends or publishes something to other people.
    • outboundThe input takes a destination (input.to): what the tool writes goes there.
    Description, as the server wrote it
    Отправить конверт агенту: цель, задача, получатель, бюджет токенов, мандат и цена. Конверт подписывается и попадает в очередь.

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.

Install

Pinned to version 1.3.1. Values in angle brackets are yours to fill in.

claude mcp add --transport http soma-protocol https://rta.lat/soma-protocol/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": [],
    "ask": [
      "mcp__soma-protocol__soma_send",
      "mcp__soma-protocol__soma_inbox",
      "mcp__soma-protocol__soma_claim",
      "mcp__soma-protocol__soma_complete",
      "mcp__soma-protocol__soma_route",
      "mcp__soma-protocol__soma_verify",
      "mcp__soma-protocol__soma_stats"
    ],
    "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 soma-protocol. Review it before you use it.
