## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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 (7)

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

### `riptide_allocation`

Description, as the server wrote it:

```untrusted-server-text
Latest allocation committed by the independent daily paper job.
```

### `riptide_crypto_record`

- 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
Separate toy crypto strategy paper record and honesty boundary.
```

### `riptide_event_markets`

- 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
Policy-gated committed Event Intelligence availability, eligible quotes, and gaps.
```

### `riptide_methodology`

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

```untrusted-server-text
Public methodology, safety boundaries, and canonical links.
```

### `riptide_overview`

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

```untrusted-server-text
Riptide health, latest allocation, both paper records, and links.
```

### `riptide_paper_record`

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

```

### `riptide_risk_evidence`

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

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |

- **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 7 tools that change things (7 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.seiche.info/riptide/mcp: tools/list returned 7 tools to an anonymous client, including riptide_allocation (write), riptide_crypto_record (write), riptide_event_markets (write), riptide_methodology (write), riptide_overview (write) and 2 more
