## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `dfm_feedback`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Rule-based design-for-manufacturability feedback for a part specification.
```

### `estimate_bom`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Estimate costs for a multi-part bill of materials in one call.

    Each part: {process, quantity, material?, bounding_box_mm?, tolerance_mm?,
    finish?}. Returns per-line estimates, a BOM total, and the longest lead
    time. Indicative and non-binding. Max 50 lines.
    
```

### `refine_quote`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Refine a previous estimate (change quantity, material, tolerance, finish) by passing its quote_token.
```

### `request_quote`

- The name "request_quote" says "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Get an instant cost estimate for a custom manufactured part. Returns unit price, total, lead time, and assumptions. Indicative and non-binding.
```

## Only reads (3)

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

### `compare_processes`

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

Description, as the server wrote it:

```untrusted-server-text
Compare cost and lead time for one part across manufacturing processes.

    Provide 2-8 process names and a quantity; returns per-process estimates
    sorted by total cost, plus a lowest-cost / shortest-lead-time note.
    Indicative and non-binding.
    
```

### `discover_capabilities`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List supported manufacturing processes, materials, and the fields an estimate accepts.
```

### `get_lead_time`

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

Description, as the server wrote it:

```untrusted-server-text
Estimated production lead time in days, by process and quantity.
```

## Claude Code permissions

    ],
    "deny": []
  }
}
