## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__emporion__business_days` `mcp__emporion__company_lookup` `mcp__emporion__domain_rdap` `mcp__emporion__eori_check` `mcp__emporion__fx_rate` `mcp__emporion__lei_lookup` `mcp__emporion__sanctions_screen` `mcp__emporion__vat_check` |
| 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.


## Changes things (6)

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

### `business_days`

- 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
Business days: is this date a working day in a country (or region) or on a market (TARGET2, NYSE, LSE…), the holiday's name, next and previous business day, date + N business days, business days between two dates, a year's holidays. Offline, python-holidays.
```

### `domain_rdap`

- 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
Who registered this domain and when? RDAP from the TLD's own registry (found through IANA's bootstrap): created, updated, expires, age in days, registrar, status, nameservers, DNSSEC. Or registered: false. A TLD without RDAP costs nothing.
```

### `eori_check`

- 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
Is this EORI number valid for EU customs? The European Commission's EOS service, up to 10 numbers per call; name and address where the operator consented to publication. A service that is down costs nothing.
```

### `fx_rate`

- 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
ECB euro reference rate for any pair on any date since 1999 (the latest ECB day on or before it, named), cross rates through the euro in Decimal, optional amount rounded to the currency's minor units. Reference rate, not a dealing rate.
```

### `sanctions_screen`

- 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
Is this wallet address or name on a public sanctions list? OFAC SDN (incl. ~500 digital-currency addresses), EU and UK lists — UN designations through them, each hit with its UN number — with each list's date and SHA-256. A lookup, not a compliance determination.
```

### `vat_check`

- 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
Is this EU VAT number valid today? Asks VIES (the member state's registry): valid, registered name and address, check time. Pass requester_vat (your own EU VAT number) to get VIES's consultation number — official proof of the check in your name. A registry that is down costs nothing.
```

## Only reads (2)

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

### `company_lookup`

- The name "company_lookup" says "lookup": 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
Is this company real and alive? Its national register by number or name: Norway (Brønnøysund), France (SIRENE/RNE), Czech Republic (ARES), Finland (PRH). Name, status, legal form, founding date, address, VAT number where published, plus the register's own fields.
```

### `lei_lookup`

- The name "lei_lookup" says "lookup": 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
Who is this legal entity? GLEIF LEI record by LEI (check digits verified locally) or by name (ranked candidates): legal name, jurisdiction, legal form, status, addresses, registration and renewal, direct and ultimate parents. CC0.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__emporion__company_lookup",
      "mcp__emporion__lei_lookup"
    ],

      "mcp__emporion__domain_rdap"
    ],
    "deny": []
