## 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__mri__mri_get_cited_sources` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__mri__mri_get_domain` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Only reads (4)

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

### `mri_get_category`

- The name "mri_get_category" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return one category's question shapes (best tools, how buyers choose, comparisons, top lists, problem-first research, is it worth it, news) and the evidence state of each: published with rates, collecting, or not collectable.
```

### `mri_get_cited_sources`

- The name "mri_get_cited_sources" says "get": a word for reading.
- Tag private-data: The description's first sentence says "database": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
Ranked source domains that AI answer engines cite for one category and question shape, with citation rate (share of monitored answer runs citing the domain), rank, percentile and source role (editorial publication, vendor-owned, analyst research, community, academic/government, market database, wire distribution). Use to answer 'which publications/sources does ChatGPT or Perplexity cite for <category>' or 'where should a <category> brand earn coverage to be cited by AI'.
```

### `mri_get_domain`

- The name "mri_get_domain" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
For one domain or URL, return how often AI answer engines cite it: overall citation rate, which engines cite it, confidence tier, rank among all cited domains and within its source role, and per-category segment rates. Use to answer 'does ChatGPT/Perplexity cite <site>' or 'how authoritative is <publication> as an AI source'.
```

### `mri_list_categories`

- The name "mri_list_categories" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List every Machine Relations Index category (e.g. cybersecurity, fintech, enterprise-software, ai-visibility-geo) with the question shapes that have published citation rates, plus the source-role vocabulary. Call this first to get a valid category key.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__mri__mri_list_categories",
      "mcp__mri__mri_get_category",
      "mcp__mri__mri_get_cited_sources",
      "mcp__mri__mri_get_domain"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__mri__mri_get_cited_sources`: private-data
- `mcp__mri__mri_get_domain`: untrusted-input
