## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__stores__get_agent_profile` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__stores__ai_shopping_observatory` `mcp__stores__find_store` `mcp__stores__get_agent_profile` `mcp__stores__list_store_categories` `mcp__stores__store_details` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `store_details` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "store_details" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "store_details" says "store": a word for a change.
```

- **warn** Annotations that disagree with the tool in `get_agent_profile` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "get_agent_profile" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "get_agent_profile" says "get": a word for reading.
```


## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `ai_shopping_observatory`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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: {}
```

### `get_agent_profile`

- The name "get_agent_profile" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag private-data: The description's first sentence says "file": it reads files.
- Tag untrusted-input: The description's first sentence says "http": it reads web pages, which anyone can write.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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"}
```

### `store_details`

- The name "store_details" says "store": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
One store's record: UCP version and MCP endpoint, capabilities, tools listed, countries it ships to, robots.txt rules for agents, last checks, and the exact search_catalog call.
Example: {"domain":"allbirds.com","country":"US"}
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `find_store`

- The name "find_store" says "find": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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"}
```

### `list_store_categories`

- The name "list_store_categories" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
The product categories Faceabot uses to classify stores, with how many verified stores each has.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `stores`:

```json
{
  "permissions": {
    "allow": [
      "mcp__stores__find_store",
      "mcp__stores__list_store_categories"
    ],
    "ask": [
      "mcp__stores__store_details",
      "mcp__stores__get_agent_profile",
      "mcp__stores__ai_shopping_observatory"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__stores__find_store`: untrusted-input
- `mcp__stores__store_details`: untrusted-input
- `mcp__stores__get_agent_profile`: private-data, untrusted-input
- `mcp__stores__list_store_categories`: untrusted-input
- `mcp__stores__ai_shopping_observatory`: untrusted-input
