## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `calculate_roi_scenario`

- 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 hypothetical daily revenue after an illustrative time/hashrate-based developer fee and electricity cost using user-supplied inputs. H*q*(hours/24)*(1-f/100) - (W/1000)*hours*t. This is a scenario, not a profit forecast or a statement of actual VNISH fees. Use pre-fee gross hashrate; do not deduct the fee twice.
```

## Only reads (2)

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

### `find_ninja_reference`

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

Description, as the server wrote it:

```untrusted-server-text
Return a selected public VNISH Ninja guide about control-board identification, installation SSH errors, or return-to-stock preparation. A reference is not a device-specific installation or recovery instruction. No device connection or action is performed.
```

### `lookup_firmware`

- The name "lookup_firmware" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find records in a dated snapshot of the public vnish.global firmware catalog. Use the exact model ID; narrow by board code and version if known. Returns file size, SHA-256 and source links. A catalog record does not establish device compatibility, package authenticity, or successful hardware testing. Does not download or install firmware.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `vnish-global-operator`:

```json
{
  "permissions": {
    "allow": [
      "mcp__vnish-global-operator__lookup_firmware",
      "mcp__vnish-global-operator__find_ninja_reference"
    ],
    "ask": [
      "mcp__vnish-global-operator__calculate_roi_scenario"
    ],
    "deny": []
  }
}
