3 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
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.

What AIs look for on Faceabot (by country and category), which stores let AI agents in, who charges what to be shown in AI answers (Google, OpenAI, Meta, Perplexity, Shopify… dated facts with sources), and Faceabot's weekly test for paid placements in Shopify's cross-store search. Example: {}

  What this check looks for
Description, as the server wrote it
UCP stores (Shopify and others) ask every agent for meta['ucp-agent'].profile: the https URL of a JSON file describing it. No website to publish one? Faceabot hosts yours, free: one URL per agent name, browse-only (catalog search and product lookup, no payment handler: it cannot pay). Same name = same URL. Faceabot never sees your searches. Example: {"agent_name":"Travel helper by Acme"}

Where can I (an AI agent) shop for this product, for my human's country? Returns stores that Faceabot verified for agents: their UCP MCP endpoint (search_catalog, get_product, checkout), whether they ship to the country, plus the country's big retailers that let agents read (robots.txt) and the Shopify cross-store search. Any language. Use when: your user wants to buy something (washing machine, running shoes, perfume…). Example: {"query":"washing machine","country":"BE"}

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 outbound.

Reads private data1: Reads files, mail, messages, databases, secrets, calendars or repositories.; get_agent_profile
Reads text others write5: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; ai_shopping_observatory
find_store
get_agent_profile
list_store_categories
store_details
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.

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.

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__stores__find_store",
      "mcp__stores__list_store_categories"
    ],
    "ask": [

      "mcp__stores__get_agent_profile",
      "mcp__stores__ai_shopping_observatory"
    ],
    "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 stores. Review it before you use it.
