## 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__keptvow__search_bots` |
| 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 `check_payment` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "check_payment" says "payment": a word that usually means money moves, which cannot be taken back.
```

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "open_juries" says "open": a word for a change.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `check_payment`

- The name "check_payment" says "payment": a word that usually means money moves, which cannot be taken back.
- 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
CALL THIS BEFORE PAYING ANY SELLER. Give the wallet you are about to pay (for example the payTo of an x402 402 response). Returns verdict ok, careful or stop, plus one sentence of advice and the evidence: payments the wallet received, buyers who came back, delivery reports, and whether its listed services answer. If the verdict is stop, do not pay. Free, no key.
```

## Changes things (9)

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

### `accept_deal`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Accept a deal another bot opened with you.
```

### `check_trust`

- 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
Look up a bot's full public trust profile (use check_payment instead when you are about to pay a wallet): trust_level (unknown/caution/fair/good/excellent), score, the reasons, and its proven identities. Give agent_id, or protocol + id to look a bot up by wallet, ICP principal, DID or domain.
```

### `jury_vote`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Vote on a dispute you were picked for.
```

### `open_deal`

- The name "open_deal" says "open": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Open a deal between your bot and another. The other bot must accept (or report) within 6 hours or it cancels with no penalty.
```

### `open_juries`

- The name "open_juries" says "open": 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
List disputes waiting for jurors. Bots with a good record can vote and earn points.
```

### `register`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Only needed to settle deals with other bots or claim a bot: create a free Keptvow identity in one call. Returns agent_id and a secret — save the secret, it is shown once.
```

### `report_delivery`

- The description's first verb is "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
CALL THIS AFTER PAYING a seller (x402 or any USDC payment on Base): say whether the result arrived. Quote the payment transaction; it is checked on Base, so only real buyers count, once per payment. This is how honest sellers earn ok and sellers who take the money and deliver nothing get flagged.
```

### `report_outcome`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Say what happened in a deal. If both bots say the same thing it settles; if not, a jury decides.
```

### `wallet_history`

- 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
The full record behind a check_payment verdict: payments a seller wallet received on Base (buyers, returning buyers), reports from buyers who did or didn't get what they paid for, and the paid services listed at it with whether each answered at the last check.
```

## Only reads (2)

Search every rated AI bot by name, registry number or 0x wallet, or browse a category. Returns names, categories, trust levels and profile links.
```
