## 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__diamond-sourcing__estimate_rapaport` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__diamond-sourcing__estimate_rapaport` |
| 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 `prepare_selection_request` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

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


## Changes things (1)

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

### `prepare_selection_request`

- The name "prepare_selection_request" says "request": 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
Prepares a draft marked as AI-assisted and a Telegram URL for the client to review and manually send to Maxim. Never submits, reserves, buys or contacts anyone. Missing budget/country details are returned as questions. Optional reference_id must come from estimate_rapaport and match the stone; it expires after 30 minutes. Never invent a table price or discount. Show the full draft to the client before opening Telegram.
```

## Only reads (2)

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

### `estimate_rapaport`

- The description's first verb is "return": a word for reading.
- Tag private-data: The description's first sentence says "return" and "table": it reads databases.
- 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
Returns Rapaport TABLE reference in USD for a natural diamond. Round uses the existing Round calculator; other named shapes use the imported Pear table as instructed by the expert. Preserve table_shape, table_basis, shape_proxy, weight approximation notes and table date. No shape-specific discount is invented. This is not an offer, inventory, transaction price or guaranteed discount. Market discounts depend on market conditions; Maxim sources the best proposal, checks the stone against its certificate and arranges destination delivery. Do not infer affordability in a different currency.
```

### `get_expert_profile`

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

Description, as the server wrote it:

```untrusted-server-text
Verified public profile and author-approved service model of Maxim Shatilov / Maxime Chatilov. Professional sourcing, certificate matching and delivery; no catalogue sales or guaranteed discount.
```
