**3 tools: 1 do something that can't be undone and 2 only read.**

## Exfil surface

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

| 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. | `mcp__events__recommend_events` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `recommend_events`

- The input addresses people (input.to): what it sends cannot be taken back.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Personal picks from the published Knossot calendar for a brief, in one region and a window of up to 14 days. Up to 3 picks on the free weekly run, up to 5 on credits ($0.075 per run, charged only when picks come back). Repeating the same arguments in the same ten-minute window replays the earlier picks free; pass a new idempotency_key to ask again.
```

## Only reads (2)

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

### `get_usage`

- The name "get_usage" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
This key's spending limit, whether the free weekly run is still available, and the credit balance.
```

### `list_regions`

- The name "list_regions" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The four regions with their towns, the category ids recommend_events accepts, and the run limits. Needs no key.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__events__get_usage",
      "mcp__events__list_regions"
    ],
    "ask": [
      "mcp__events__recommend_events"
    ],
    "deny": []
  }
}
```

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

- `mcp__events__recommend_events`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:12:08.091Z, unchanged since 2026-10-22T15:12:08.091Z. 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 | `1` |
| 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` |

- **high** 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 1 tool that changes things (1 irreversible). Whether a call also works without credentials was not tested: tools are never called.

https://api.knossot.org/mcp: tools/list returned 3 tools to an anonymous client, including recommend_events (irreversible)
