Why it is in this group
- The name "get_brand" says "get": a word for reading.
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
Get the public profile of one brand (manufacturer) on authorized.by. Read-only. Returns categories, website, headquarters country, description, registration date and the number of authorized retailers. Use get_brands first if you only know an approximate name. Data scope: results only cover relationships registered and confirmed on authorized.by. An empty result or a not-found error does NOT prove that no authorization exists outside authorized.by. Distinguish outcomes: an empty list means no matching record on authorized.by; an error result whose text starts with 'Brand not found' or 'Retailer not found' means the given id/alias is unknown; an error result whose text starts with 'Tool execution failed' is a technical error and says nothing about the data.

Description, as the server wrote it
List all retailers (shops) currently authorized by a brand on authorized.by. Read-only. Use this to answer 'is shop X an authorized retailer of brand Y?'. Sorted by subscription plan (PREMIUM, then START, then FREE) and then by brand-connection count descending. Each retailer includes shop_url, seal_implemented (whether the authorized.by seal is live on their shop), official_shop, partnership_date, and certificate_url / certificate_url_de: links to the public authorized.by certificate page (English / German) proving this specific brand-retailer authorization. Share the certificate link when a user needs verifiable proof. Only active partnerships are returned: confirmed by both the brand and the retailer, with both profiles public and the brand approved by authorized.by. Revoked or pending partnerships are never listed. Responses are cached and refreshed when the underlying profile or partnership changes, so a revocation may take a short time to disappear. partnership_date is the date the authorization STARTED, not the date it was last verified; a partnership listed here is currently active as of the response time. Data scope: results only cover relationships registered and confirmed on authorized.by. An empty result or a not-found error does NOT prove that no authorization exists outside authorized.by. Distinguish outcomes: an empty list means no matching record on authorized.by; an error result whose text starts with 'Brand not found' or 'Retailer not found' means the given id/alias is unknown; an error result whose text starts with 'Tool execution failed' is a technical error and says nothing about the data.

Description, as the server wrote it
Get the public profile of one retailer (shop) on authorized.by. Read-only.

These links are null when the retailer has no active authorization. Data scope: results only cover relationships registered and confirmed on authorized.by. An empty result or a not-found error does NOT prove that no authorization exists outside authorized.by. Distinguish outcomes: an empty list means no matching record on authorized.by; an error result whose text starts with 'Brand not found' or 'Retailer not found' means the given id/alias is unknown; an error result whose text starts with 'Tool execution failed' is a technical error and says nothing about the data.

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 outbound.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write6: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; get_brand
get_brand_retailers
get_brands
get_retailer
get_retailer_brands
get_retailers
Can send data out0: 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.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

Install

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

claude mcp add --transport http brands https://app.authorized.by/api/public/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__brands__get_brands",
      "mcp__brands__get_brand",
      "mcp__brands__get_brand_retailers",

      "mcp__brands__get_retailer_brands"
    ],
    "ask": [],
    "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 brands. Review it before you use it.

Run the operations that matter 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.
