## 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__boatday__get_boat_model` `mcp__boatday__get_state_boating_rules` `mcp__boatday__get_yard` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__boatday__find_yards` `mcp__boatday__get_boat_model` `mcp__boatday__get_seacoast_costs` `mcp__boatday__get_yard` |
| 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 `get_state_boating_rules` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

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


## Changes things (3)

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

### `estimate_boat_value`

- 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
Instant used-boat value estimate (low/mid/high band with method + confidence). Provide modelId, or make+model+year, or loaFt+boatType, or a HIN. Educational, not an appraisal.
```

### `estimate_total_cost_of_ownership`

- 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
Annual + hold-period total cost of ownership (storage, insurance, maintenance, fuel, fees, depreciation) as bands. Side-effect free.
```

### `get_state_boating_rules`

- The name "get_state_boating_rules" says "get": a word for reading.
- The input takes a statement or command to run (input.code), 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 "note": it reads notes.
- Findings: warn annotation-conflict

```untrusted-server-text
US state boating rules: registration, titling, boater education, BUI, PFD notes, official agency links. Omit code for the index.
