## 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__pumpfun-trends__recent_launches` `mcp__pumpfun-trends__trending_topics` |
| 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.


## Only reads (2)

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

### `recent_launches`

- The description's first verb is "list": a word for reading.
- 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
Lists pump.fun token launches from the last N minutes (decoded from Solana mainnet within about a minute), each with its creator wallet, that wallet's seven-day launch count, and, when the coin's name matches a topic currently trending on Google Trends or moving on Polymarket, the matched trend with its source and score. Launch data only; it does not rate, recommend or trade anything. Price: $0.005 per call in USDC (x402).
```

### `trending_topics`

- The description's first verb is "list": a word for reading.
- 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
Lists topics trending right now across Google Trends (US realtime) and Polymarket (markets moving on volume), merged by topic, strongest first, each with score, score velocity per hour, first and last seen times, a type label (person, brand, event, place, meme, other), the headlines or market numbers behind it, and how many pump.fun launches in the last hour match it. Sources are polled every five minutes. Price: $0.01 per call in USDC (x402).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__pumpfun-trends__recent_launches",
      "mcp__pumpfun-trends__trending_topics"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__pumpfun-trends__recent_launches`: untrusted-input
- `mcp__pumpfun-trends__trending_topics`: untrusted-input
