## Exfil surface

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

| 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__nibgate__resolve_share` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__nibgate__resolve_share` |

## Findings

No check matched anything in these tool definitions.


## Only reads (5)

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

### `explore_content`

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

Description, as the server wrote it:

```untrusted-server-text
Search verified creator content on Nibgate. Returns content metadata (title, type, price, domain, reputation, unlock path). Use to discover what paid/free content exists.
```

### `get_leaderboards`

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

Description, as the server wrote it:

```untrusted-server-text
Get ranked creators, sites, or content by reputation score, unlocks, views, and revenue (unlocks + tips + nibshares).
```

### `get_ledger`

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

Description, as the server wrote it:

```untrusted-server-text
Get the public Nibgate activity ledger: recent views, unlocks, payments, tips (including funded pending holds marked status=held), onchain ratings, and privacy-safe nibshare views/unlocks (titles, wallets, amounts, tx — never the private share link) across verified sites. Held tips are pending and do not count toward completed-tip totals; refunds appear as negative tip entries. Use GET /hub/tips/held?domain={domain} to check pending tips for any exact domain, including external sites. Includes wallet addresses, tx hashes, and receipts where available.
```

### `get_platform_stats`

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

Description, as the server wrote it:

```untrusted-server-text
Get platform-wide Nibgate totals: creators, verified sites, content count, views, unlocks, revenue (unlocks + tips + nibshares), tips, nibshare unlocks/views/revenue, and cumulative protocol fees.
```

### `resolve_share`

- The name "resolve_share" says "resolve": a word for reading.
- Tag untrusted-input: The description's first sentence says "resolve" and "http": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Resolve a Nibshare link (https://nibgate.xyz/ns/<slug> or a bare slug) to its machine-readable manifest: title, price, currency, content type, status, expiry, and the page/access/unlock/media URLs. Use before attempting payment or access.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__nibgate__explore_content",
      "mcp__nibgate__get_ledger",
      "mcp__nibgate__get_platform_stats",
      "mcp__nibgate__get_leaderboards"
    ],
    "ask": [
      "mcp__nibgate__resolve_share"
    ],
    "deny": []
  }
}
```

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

- `mcp__nibgate__resolve_share`: untrusted-input, outbound
