## 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__actiongate__top_up` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `policy_gate` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "policy_gate" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "apply": a word for a change.
```


## Changes things (5)

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

### `policy_gate`

- The description's first verb is "apply": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Apply treasury policy to a proposed action and return allow, deny, or allow-with-limits. Paid via x402 or API key credits. Free tier: 10 policy gate calls/day per client.
```

### `request_api_key`

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

Description, as the server wrote it:

```untrusted-server-text
Provision a prepaid ActionGate API key with $1.00 of starter credits for this operator email.
```

### `risk_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
Score the risk of a proposed agent action before execution. Paid via x402 or API key credits. Free tier: 20 risk score calls/day per client.
```

### `simulate`

- 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
Estimate cost, failure risk, and notable side effects for a proposed action. Paid via x402 or API key credits. Free tier: 20 simulate calls/day per client.
```

### `top_up`

- The description's first verb is "generate": a word for a change.
- 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
Generate a Stripe Checkout link so the human operator can add prepaid credits to an existing ActionGate API key.
```

## Only reads (1)

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

### `balance`

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

Description, as the server wrote it:

```untrusted-server-text
Return the current prepaid credit balance and usage count for an ActionGate API key.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__actiongate__balance"
    ],
    "ask": [
      "mcp__actiongate__request_api_key",
      "mcp__actiongate__top_up",
      "mcp__actiongate__risk_score",
      "mcp__actiongate__simulate",
      "mcp__actiongate__policy_gate"
    ],
    "deny": []
  }
}
```

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

- `mcp__actiongate__top_up`: untrusted-input
