## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `check_bands`

- 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
Paste the LTE (and optionally 5G NR) bands of any cellular module or device and get a verdict on every network of one or more countries, with the bands it lacks, using the same rules as Band Atlas: bands cross-checked by two sources are scored, coverage bands under 1 GHz weigh double, good needs at least 60 percent and a coverage band.
```

### `check_device`

- 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
Verdict (good, limited or no) for a known module or device on every network of a country, with the LTE and NR bands it lacks. Use list_coverage for device ids, or check_bands for a device that is not listed.
```

### `iot_readiness`

- 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
The Band Atlas IoT connectivity readiness index (beta, 0-100) for the given countries, or the top 20 when none are given: coverage (share of networks with a sub-1 GHz 4G band, 30%), LTE-M and NB-IoT confirmed on at least one network (30%), 5G and RedCap (20%), device fit (20%), with rank and data confidence. Only confirmed data counts; "not listed" is never taken as "not available", so thinly documented countries may be under-scored.
```

### `project_report`

- 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
One report for a device across several target countries: where it works as is, where it needs attention (with the indoor-coverage risk when a network's own coverage band is missing) and where it does not work, plus a link to the full report on the website (PDF, share link, ask an engineer to confirm).
```

## Only reads (3)

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

### `find_devices`

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

Description, as the server wrote it:

```untrusted-server-text
Rank the modules and devices in Band Atlas by how many networks of the given countries rate them good, and say which device works well on every network of each country. Useful to pick the fewest SKUs for a multi-country deployment.
```

### `get_country_networks`

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

Description, as the server wrote it:

```untrusted-server-text
Mobile networks of one country: their 4G/LTE and 5G/NR bands (each marked cross-checked by two independent sources or single-source), core bands, and the state of 2G, 3G, 5G SA, RedCap, LTE-M and NB-IoT, with switch-off dates.
```

### `list_coverage`

- The name "list_coverage" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List every country (ISO code, name, number of networks) and every module or device (id, name, kind) Band Atlas covers. Call this first if you are unsure of a country code or a device id.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `band-atlas`:

```json
{
  "permissions": {
    "allow": [
      "mcp__band-atlas__list_coverage",
      "mcp__band-atlas__get_country_networks",
      "mcp__band-atlas__find_devices"
    ],
    "ask": [
      "mcp__band-atlas__check_device",
      "mcp__band-atlas__check_bands",
      "mcp__band-atlas__project_report",
      "mcp__band-atlas__iot_readiness"
    ],
    "deny": []
  }
}
