## Exfil surface

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

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

## Findings

- **warn** Mentions of other tools or servers in `status` ([tool-shadowing](https://anlyon.dev/methodology#tool-shadowing))

```untrusted-server-text
The description contains "every other tool", wording about other tools or servers.

description: "...henticated on the hosted connector like every other tool; the underlying /v1/status route itself..."
```

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

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

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

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

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

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


## Changes things (2)

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

### `get_ownership`

- The name "get_ownership" says "get": a word for reading.
- The description's first verb is "schedule": 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
Schedule 13D/13G reporting-owner records for an issuer, newest filing first. Structured XML filings from 2024-12-18 only. Costs 3 credits. A figure can be withheld (null/absent beats a guess). A figure can change or disappear when a later filing arrives; figures are not versioned. Read `adjustments` for extractor decisions beyond copying one filed figure. This is filing data, not investment advice.
```

### `get_statements`

- The name "get_statements" says "get": a word for reading.
- The input takes a statement or command to run (input.statement), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag private-data: The description's first sentence says "document": it reads documents.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Statements as filed, one document per filing and statement, newest filing first. Costs 3 credits. One page only: pass `limit` (1–20, default 4) and `cursor` from `meta.next_cursor`. Do not assume every page is fetched. A typical page of 4 documents is about 45 KB (median in the pilot sample); large pages stay under the API document budget (~4 MB). A figure can be withheld (null/absent beats a guess). A figure can change or disappear when a later filing arrives; figures are not versioned. Read `adjustments` for extractor decisions beyond copying one filed figure. This is filing data, not investment advice.
```
