## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__meter369__game_facts` |
| 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.

### `game_facts`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Use this when you need live game metadata from RAWG (release date, ratings, Metacritic, platforms, genres). Pay-per-call: $0.03 USDC on Base via x402 to the REST route POST /v1/game/facts.
```

### `hook_score`

- 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
Use this when you need a gaming headline or hook scored 0-100 against the 369 team's hook rules. Pay-per-call: $0.01 USDC on Base via x402 to the REST route POST /v1/hook/score.
```

### `translate_check`

- 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
Use this when you need an EN<->FA translation QA score 0-100 (numbers/entities preserved, script purity, untranslated segments). Pay-per-call: $0.02 USDC on Base via x402 to the REST route POST /v1/translate/check.
```

## Only reads (1)

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

### `text_analyze`

- The name "text_analyze" says "analyze": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when you need deterministic text analysis (counts, Flesch readability, script mix, top keywords). Pay-per-call: $0.01 USDC on Base via x402 to the REST route POST /v1/text/analyze.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `meter369`:

```json
{
  "permissions": {
    "allow": [
      "mcp__meter369__text_analyze"
    ],
    "ask": [
      "mcp__meter369__hook_score",
      "mcp__meter369__translate_check",
      "mcp__meter369__game_facts"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):
