## 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__entyrix__get_company_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 `screen_companies` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "run": a word for a change.
```


## Changes things (4)

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

### `check_compliance`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Lightweight public compliance snapshot for one company (works without an account): sanctions screening, insolvency, debtor registers, VAT reliability. For the full KYB picture use kyb_check. A null field means WITHHELD or not measured — it does NOT mean clean.
```

### `company_brief`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Compact, deterministic Markdown brief of one company (≤12 KB): identity, address, industry, latest financials, credit score and recommended limit, cyber score, risk flags (insolvency, tax debt, sanctions), NIS2 status and key people where licensed. The best single call for 'tell me about company X'. Accepts every registry identifier shape we carry (SK/CZ IČO, AT Firmenbuch e.g. '033209m', PL REGON, FR SIREN, …); pass `country` for anything that is not an 8-digit IČO. Every fact comes from the database — missing data is marked, never invented.
```

### `kyb_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.

Description, as the server wrote it:

```untrusted-server-text
One-call Know-Your-Business summary for one company: registry status, insolvency, liquidation, sanctions screening, debarment, tax/social/health debts, VAT reliability and the overall risk verdict. Use before onboarding a customer or supplier. A null field means WITHHELD or NOT MEASURED — it does NOT mean clean; say so when you report it.
```

### `screen_companies`

- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Run kyb_check on up to 25 companies at once and get one compact row per company (status, insolvency, sanctions, debts, verdict). Use for supplier lists or portfolios. Each company counts as one API request against your rate limit. Requires an authenticated account.
```

## Only reads (9)

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

### `advanced_search`

- The name "advanced_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Structured company search for portfolio building and market sizing — NOT for finding one known company (use search_companies). Filters: country, NACE prefix, status, region, turnover range (EUR), employee range, founding date range, VAT payer, tax debt, sanctions. Results are paged (limit + offset); the response says how many matched. Only the listed arguments exist — anything else is rejected, never silently ignored.
```

### `find_suppliers`

- The name "find_suppliers" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Public procurement contracts this company is party to (SK CRZ + CZ Registr smluv), newest first, paged. HONEST SCOPE: this is business-to-government procurement, NOT a commercial supply chain — do not present it as one.
```

### `get_company_details`

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

Description, as the server wrote it:

```untrusted-server-text
Full record for one company: identity, address, legal form, status flags, NACE, and the whole enrichment layer we hold (web, tech stack, NIS2, EU funds, LEI, HU de minimis state aid granted, HU public procurement from EKR, …). Large — prefer company_brief unless you need a specific field. Natural-person fields are gated and may be withheld; a withheld field is not the same as an empty one.
```

### `get_company_network`

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

Description, as the server wrote it:

```untrusted-server-text
Companies connected to this one through shared officers or owners (one hop). Use for group structure and beneficial-ownership tracing. Person names are gated like everywhere else.
```

### `get_company_relations`

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

Description, as the server wrote it:

```untrusted-server-text
Direct relations of one company — statutory officers, owners, parents, subsidiaries, M&A events — without traversing the wider graph. `shareholders` are owners only; members of the supervisory board are in `supervisoryBoard`. SK M&A events: effectiveDate is the date stated by the register; when missing, derivedEffectiveDate may carry a date INFERRED from the absorbed firm's deregistration (effectiveDateSource: "derived") — present it as an estimate, never as a register fact.
```

### `get_financials`

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

Description, as the server wrote it:

```untrusted-server-text
Filed financial statements of one company, one row per fiscal year (newest first), with revenue, profit, assets, equity, liabilities and year-over-year trend. Amounts are EUR CENTS as integers (divide by 100 for euros). Use for trend and solvency questions; company_brief already carries the latest year.
```

### `list_rankings`

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

Description, as the server wrote it:

```untrusted-server-text
A published ranking by its slug (e.g. largest employers, top taxpayers). Call WITHOUT a key first to list the available slugs — inventing one returns an error.
```

### `lookup_company`

- The name "lookup_company" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Resolve exactly one company by its national registry identifier in a given country. Handles every identifier shape we carry (SK/CZ/EE IČO, AT Firmenbuch e.g. '187a', SI/LV registry numbers, …). Returns the core record: identity, address, legal form, status, NACE. For an LLM-ready summary prefer company_brief; for the full enrichment layer use get_company_details.
```

### `search_companies`

- The name "search_companies" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find companies by name (or name fragment) across the pan-European dataset. Returns ranked candidates with registry identifier, country, legal form and status. Use this FIRST when you only know a name; then pass the identifier + country to lookup_company or company_brief. Do not use it to filter by industry or size — that is advanced_search.
```

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://entyrix.com/mcp/v1: tools/list returned 13 tools to an anonymous client, including company_brief (write), kyb_check (write), screen_companies (write), check_compliance (write)
