## 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__whp-standing__whp_standing_evaluation` |
| 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.

### `whp_evaluate`

- The name "whp_evaluate" says "evaluate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Evaluate a proposition under Decision Integrity Protocol and receive an Ed25519-signed Standing determination. Calling without payment returns the exact 1 USDC Base payment challenge. Pass payment_signature to settle and receive the signed determination.
```

### `whp_standing_contract`

- 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
Discover WHP Standing: Machine-verifiable standing under explicit authority and bounds. Includes exact profile, schema, authority prerequisites and owner-authorized payment contract.
```

### `whp_standing_evaluation`

- The description's first verb is "request": 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
Request a WHP Standing Evaluation. First call returns the exact HTTP 402 payment terms. Supply only the buyer’s own pre-authorized payment signature on retry. Paying does not establish standing; a failed assessment has no Mark.
```

## Only reads (1)

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

### `whp_standing_result`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve the exact original WHP Standing Mark or negative assessment bytes with buyer authentication, without another charge.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__whp-standing__whp_standing_result"
    ],
    "ask": [
      "mcp__whp-standing__whp_evaluate",
      "mcp__whp-standing__whp_standing_contract",
      "mcp__whp-standing__whp_standing_evaluation"
    ],
    "deny": []
  }
}
```

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

- `mcp__whp-standing__whp_standing_evaluation`: untrusted-input
