## 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

No check matched anything in these tool definitions.


## Changes things (3)

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

### `fw_check_cli`

- 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
Checks a pasted `diff all` / `dump` against a release: every `set` line whose setting does not exist, was renamed or removed, or whose value is out of range or not in the value list, plus lines that only repeat the firmware default. The release of the paste is read from its `# Betaflight / ... X.Y.Z` or `# INAV/<target> X.Y.Z` header, which also picks the firmware when none is given. Other commands (aux, serial, resource) are counted, not checked.
```

### `fw_param`

- 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 CLI setting of a firmware release: type, allowed range or values, firmware default (with no board config), the source line (settings.c or settings.yaml), and its history across releases (renames, range and default changes). Old names are followed through sourced renames.
```

### `part_specs`

- 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 full spec sheet of one part by its slug (the last segment of its fpv-db.com URL, e.g. iflight-xing2-2207 for /motors/iflight-xing2-2207/): specs, bench thrust table where measured, VTX table where published, the sources the specs were verified against, and caveats.
```

## Only reads (2)

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

### `fw_diff`

- The name "fw_diff" says "diff": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
What changed in the CLI settings between two releases: added, removed, renamed (only sourced renames) and changed (range, values, default) settings.
```

### `search_parts`

- The name "search_parts" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Finds published parts of one type by spec. `filters` maps a spec field to a number (equals, or any element of a list), a string (case-insensitive substring) or {min, max} (numeric range). `query` matches brand and model. An unknown field returns the type's field list. Example: type=motor, filters={"stator": "2207", "weight_g": {"max": 33}}.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__fpv-db__fw_diff",
      "mcp__fpv-db__search_parts"
    ],
    "ask": [
      "mcp__fpv-db__fw_param",
      "mcp__fpv-db__fw_check_cli",
      "mcp__fpv-db__part_specs"
    ],
    "deny": []
  }
}
