**7 tools: 3 change things and 4 only read.**

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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 `calculate_laser_setup` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "calculate_laser_setup" 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 "add": a word for a change.
```


## Changes things (3)

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

### `calculate_etsy_payback`

- 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
Calculate profit, break-even sales/months and capacity from explicit user inputs. No tax or wage deduction; no predicted sales or prefilled Etsy fees.
```

### `calculate_laser_setup`

- The description's first verb is "add": 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
Add a user-supplied machine quote and explicitly selected accessory costs in one currency. Include all eight checklist entries; use null for an unknown cost, not an assumed zero.
```

### `calculate_maker_price`

- 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
Calculate a starting selling price from explicit per-item costs, machine/hands-on minutes, hourly costs, user-supplied fees and a profit buffer. No fee lookup or currency conversion.
```

## Only reads (4)

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

### `compare_machines`

- The name "compare_machines" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare two to four known machine IDs using dated specifications, setup requirements, strengths, limitations and sources. No overall score or invented compatibility.
```

### `find_laser_material`

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

Description, as the server wrote it:

```untrusted-server-text
Return the existing cautious source-level laser/material/task guidance and sources. Unknown material means stop. This is not certification of safety or exact machine compatibility.
```

### `find_machines`

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

Description, as the server wrote it:

```untrusted-server-text
Filter researched machines by process, material/use, reference budget, buying-link market and workshop requirements. Unknown requirements do not satisfy explicit filters. Market links do not imply stock.
```

### `get_buying_options`

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

Description, as the server wrote it:

```untrusted-server-text
Read existing retailer links for one machine and an explicitly chosen buyer country. Includes affiliate disclosures and dated observations; never purchases or confirms live stock.
```
