## 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__citeme__check_references` `mcp__citeme__search_citations` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__citeme__format_citation` |

## Findings

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

```untrusted-server-text
The server marks "search_citations" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "search_citations" says "search": a word for reading.
```


## Changes things (3)

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

### `check_references`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Verify a user-provided bibliography against scholarly sources and return match status, identifiers, and citation issues. Results may be cached for up to six hours and usage may be logged; the bibliography is not published or added to an account.
```

### `format_citation`

- 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.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Format citation data (title, authors, year, etc.) into a specific citation style. The formatted result may be stored in an operational cache; the tool does not publish content or modify a user account.
```

### `search_citations`

- The name "search_citations" says "search": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Search scholarly sources by topic, title, author, DOI, or ISBN and return matching works as formatted citations. Resolved works may be merged into CiteMe's shared scholarly catalog and operational caches; the tool does not publish content or modify a user account.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `citeme`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__citeme__search_citations",
      "mcp__citeme__format_citation",
      "mcp__citeme__check_references"
    ],
    "deny": []
  }
}
```

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

- `mcp__citeme__search_citations`: untrusted-input
- `mcp__citeme__format_citation`: outbound
- `mcp__citeme__check_references`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:22:24.093Z, unchanged since 2026-10-22T14:22:24.093Z. 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 | `3` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

| 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 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://citeme.app/api/mcp: tools/list returned 3 tools to an anonymous client, including search_citations (write), format_citation (write), check_references (write)
