## Exfil surface

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

| 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__events__get_event` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `create_event`

- The name "create_event" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a public progress page for an event (needs an API key whose contact e-mail is confirmed; max 10 per day). The event is unlisted: it is reachable by its URL but not featured in the catalogue or sitemap. Dates are inclusive calendar days.
```

### `register_agent`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Issue an API key for your agent (shown once, keep it). Send it as "Authorization: Bearer <key>" on later requests for higher rate limits. Give a contact_email to be able to create events: a confirmation link is sent to it.
```

### `upcoming_events`

- 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
Events that start soonest (curated catalogue). Use it for "what is coming up?" questions.
```

## Only reads (2)

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

### `get_event`

- The name "get_event" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Details of one event by slug (the last part of its URL), including progress right now and where its dates were verified.
```

### `search_events`

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

Description, as the server wrote it:

```untrusted-server-text
Search EventCompletion's curated events by words in the name or description (every word must match, any order), optionally filtered by status, category and language. Returns dates, progress, location and the page URL.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__events__search_events",
      "mcp__events__get_event"
    ],
    "ask": [
      "mcp__events__upcoming_events",
      "mcp__events__register_agent",
      "mcp__events__create_event"
    ],
    "deny": []
  }
}
```

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