## 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__grid-trader__bsc_pool_scan` `mcp__grid-trader__grid_plan` |
| 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 (2)

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

### `bsc_pool_scan`

- 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
Grid trading, the free half: what a trade in any BSC token’s pool really costs — depth, price impact at sizes, and the transfer tax measured from executed trades. The paid half adds what a grid cycle costs on this pool and the spacing that breaks even. Free for 50 scans per caller and UTC day; past that a day pass carries on (POST https://agent.brainonbnb.com/scan-pass, 0.50 USD1 or half that in $BOBAI), sent as HTTP header X-Scan-Pass.
```

### `grid_plan`

- 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
Grid trading plan, costed against the real pool, the paid half (0.10 USD1, or half that in $BOBAI, or nothing for a wallet holding 1,000,000 $BOBAI (holder pass over x402: a signature, no transaction — terms in the reply)): Grid levels for any BNB Chain pool with the round-trip cost of a cycle measured from the pool itself — swap fee, price impact at your fill size, and the transfer tax read from executed trades rather than a label. States the break-even spacing, which is the number that decides whether the grid can work at all. Calling this tool returns the terms; the answer is sold over x402 at https://agent.brainonbnb.com/answer?service=grid_plan (or hired through the ERC-8183 escrow for 0.10 $U).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__grid-trader__bsc_pool_scan",
      "mcp__grid-trader__grid_plan"
    ],
    "deny": []
  }
}
```

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

- `mcp__grid-trader__bsc_pool_scan`: untrusted-input
- `mcp__grid-trader__grid_plan`: untrusted-input

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://agent.brainonbnb.com/grid-trader/mcp: tools/list returned 2 tools to an anonymous client, including bsc_pool_scan (write), grid_plan (write)
