**6 tools: 2 do something that can't be undone, 1 change things and 3 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__cre-events__calendar_subscription_link` `mcp__cre-events__recommend_for_role` |

## Findings

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

```untrusted-server-text
The server marks "recommend_for_role" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```


## Can't be undone (2)

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

### `calendar_subscription_link`

- The name "calendar_subscription_link" says "link": a word for a change.
- 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
Create a personal, auto-updating calendar feed for the given filters (or a list of event ids) and return one-click links for Google Calendar, Apple Calendar and Outlook. Each call stores a new feed record (filters only, no personal data). Give the links to the user.
```

### `recommend_for_role`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The short list of upcoming CRE conferences for a role (lenders, investors, brokers, developers, multifamily, property-managers, proptech), each with why it suits that role, then other matching events. Optional filters narrow by date, place or price.
```

## Changes things (1)

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

### `upcoming_deadlines`

- 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
Early-bird, hotel and registration deadlines in the next N days, soonest first, each with the event, organizer and registration link.
```

## Only reads (3)

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

### `compare_events`

- The name "compare_events" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare 2 to 4 events on dates, place, price, size, audience, sectors and who it suits. Use ids from search_events.
```

### `get_event`

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

Description, as the server wrote it:

```untrusted-server-text
Full record for one event by id (ids come from search_events), including community takes on whether it is worth attending when we have them.
```

### `search_events`

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

Description, as the server wrote it:

```untrusted-server-text
Find upcoming commercial real estate conferences (2026-2027) by sector, place, date, price or keyword. Every event was checked against the organizer's own site; results include dates, city, venue, posted prices, who attends, why to go, deadlines and links.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__cre-events__search_events",
      "mcp__cre-events__get_event",
      "mcp__cre-events__compare_events"
    ],
    "ask": [
      "mcp__cre-events__upcoming_deadlines",
      "mcp__cre-events__recommend_for_role",
      "mcp__cre-events__calendar_subscription_link"
    ],
    "deny": []
  }
}
```

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

- `mcp__cre-events__recommend_for_role`: outbound
- `mcp__cre-events__calendar_subscription_link`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-11-02T00:19:15.117Z, unchanged since 2026-11-02T00:19:15.117Z. 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` |
| 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 3 tools that change things (2 irreversible, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://cre.events/mcp: tools/list returned 6 tools to an anonymous client, including recommend_for_role (irreversible), calendar_subscription_link (irreversible), upcoming_deadlines (write)
```
