**4 tools: 2 change things and 2 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

| Only reads | read | 2 | allow |

## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__agent-api__fetch` |
| 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. | `mcp__agent-api__data` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `about`

- 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
What CourtWatch (https://courtwatch.tech) measures at pickleball and padel clubs, its plans, free sample day and every document id, plus its sister sites.
```

### `data`

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

Description, as the server wrote it:

```untrusted-server-text
Structured rows from the Fron Research Data API (https://api.fronresearch.com/v1): markets, venues, bookable slots and rollups of sell-through and modeled revenue. Without a key every query reads one free sample day for every venue, whatever dates are asked (the response's tier, free_day and range say what was read); a caller that connects to https://fronresearch.com/api/agent with "Authorization: Bearer <key>" reads the history its plan covers (a site's own /api/agent does not forward keys). Start with endpoint index (the sample day and endpoints), then markets or venues to get ids, then metrics. Fields, filters and how to get a key: https://fronresearch.com/data/history/
```

## Only reads (2)

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

### `fetch`

- The name "fetch" says "fetch": a word for reading.
- Tag private-data: The description's first sentence says "read" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Read one document by id (from search or about). sample/<site> returns that site's free example day as rows, CC BY 4.0.
```

### `search`

- The name "search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Ask a question in plain language. Returns the most relevant passages from CourtWatch's public pages, each with its canonical URL to cite, plus its free sample day. Set site to all to search every Fron Research site.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__agent-api__search",
      "mcp__agent-api__fetch"
    ],
    "ask": [
      "mcp__agent-api__about",
      "mcp__agent-api__data"
    ],
    "deny": []
  }
}
```

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

- `mcp__agent-api__fetch`: private-data
- `mcp__agent-api__data`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-11-13T11:20:31.821Z, unchanged since 2026-11-13T11:20:31.821Z. 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 | `2` |
| 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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://courtwatch.tech/api/agent: tools/list returned 4 tools to an anonymous client, including about (write), data (write)
