## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| 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__moneygrid-gridwatch__griddata_domain` `mcp__moneygrid-gridwatch__gridextract_markdown` `mcp__moneygrid-gridwatch__gridverify_evidence` `mcp__moneygrid-gridwatch__gridwatch_preflight` `mcp__moneygrid-gridwatch__moneygrid_fetch` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__moneygrid-gridwatch__griddata_domain` `mcp__moneygrid-gridwatch__gridextract_markdown` `mcp__moneygrid-gridwatch__gridverify_evidence` `mcp__moneygrid-gridwatch__gridwatch_preflight` `mcp__moneygrid-gridwatch__moneygrid_fetch` |

## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `griddata_domain`

- 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.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Paid read-only domain intelligence. Resolves current public DNS A-record data and returns timestamped hashed evidence. Use when an agent needs current domain/DNS evidence without maintaining its own resolver.
```

### `gridextract_markdown`

- 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.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Paid read-only web extraction for agents. Fetches one public web URL and returns bounded clean text plus evidence hash and receipt metadata. Use when an agent needs compact machine-readable page content.
```

### `gridverify_evidence`

- 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.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Paid read-only URL evidence preflight ($0.05). Checks HTTP accessibility and operational risk flags, with response-sample hash and timestamp. Does not fact-check claims, establish source credibility, or verify factual truth.
```

### `gridwatch_preflight`

- 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.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
$0.02 read-only endpoint preflight. Use before an agent depends on or pays an unfamiliar API, webhook or URL. Returns reachability, HTTP status, latency, risk flags and SHA-256 evidence. Rejects private/local hosts and malformed URLs; unreachable/upstream failures are returned explicitly rather than fabricated.
```

## Only reads (1)

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

### `moneygrid_fetch`

- The name "moneygrid_fetch" says "fetch": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
DEFAULT ($0.01/call). Fetch fresh content from one public HTTP/HTTPS URL and return up to 100k characters of machine-ready text with source metadata, timestamp and SHA-256 provenance. Use for web retrieval when you need current source content. Rejects private/local hosts, unsupported schemes, invalid URLs, oversized inputs, and upstream timeouts; failed upstream requests return explicit status/error information.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__moneygrid-gridwatch__moneygrid_fetch",
      "mcp__moneygrid-gridwatch__gridwatch_preflight",
      "mcp__moneygrid-gridwatch__gridextract_markdown",
      "mcp__moneygrid-gridwatch__gridverify_evidence",
      "mcp__moneygrid-gridwatch__griddata_domain"
    ],
    "deny": []
  }
}
```

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

- `mcp__moneygrid-gridwatch__moneygrid_fetch`: untrusted-input, outbound
- `mcp__moneygrid-gridwatch__gridwatch_preflight`: untrusted-input, outbound
- `mcp__moneygrid-gridwatch__gridextract_markdown`: untrusted-input, outbound
- `mcp__moneygrid-gridwatch__gridverify_evidence`: untrusted-input, outbound
- `mcp__moneygrid-gridwatch__griddata_domain`: untrusted-input, outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:05:14.657Z, unchanged since 2026-10-22T15:05:14.657Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `4` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **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 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://moneygrid.skibunyi.workers.dev/mcp: tools/list returned 5 tools to an anonymous client, including gridwatch_preflight (write), gridextract_markdown (write), gridverify_evidence (write), griddata_domain (write)
