## 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__catch-of-a-lifetime__conditions_check` `mcp__catch-of-a-lifetime__draft_outing` `mcp__catch-of-a-lifetime__plan_outdoor_outing` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

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

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The name "move_from_meetup" says "move": a word for a change.
```


## Changes things (5)

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

### `conditions_check`

- 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
Should this outing go ahead? Returns GO, CAUTION or NO-GO with reasons, from the National Weather Service forecast and active alerts, live USGS river gauges (flow and 6-hour trend) for paddling, rafting, fishing and swimming, NOAA tide times on the coast, and sun and moon times. Works in launch metros or anywhere in the US with latitude and longitude.
```

### `draft_outing`

- 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
For hosts: turns a plan into a filled-in Catch of a Lifetime outing. Returns a link that opens the app's Plan an outing screen with the name, time, length, meeting spot, group size, notes and weekly repeat already set, plus a conditions check when it's within a week. Nothing is posted until the host taps Post. Times accept "9am", "6:30 pm", "sunrise", "sunset" or "full dark".
```

### `move_from_meetup`

- The name "move_from_meetup" says "move": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
For organizers leaving Meetup: paste the group's name, its description and its schedule (one event per line) and get a 4-week plan. Includes a ready Tribe description, one-tap weekly outing drafts for each recurring event, and an announcement to post to members. Uses only the text provided; it never accesses Meetup or member data.
```

### `outing_promo_kit`

- 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
For hosts: everything needed to fill an outing. Ready-to-paste text for iMessage and WhatsApp, an Instagram or Facebook caption with hashtags, a Facebook group or Nextdoor post, story text, a day-before reminder, a morning-of message, an after-outing recap, and a 5-slide carousel outline.
```

### `plan_outdoor_outing`

- 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
Plans a day outside in a US launch metro: National Weather Service forecast, a conditions read for the specific activity (rain, storms, wind, heat, clouds), sunrise/sunset/full-dark times, moon phase, practical tips, and local context. Good for stargazing, fishing, hiking, birding, bouldering, paddling, hunting, cold-water swimming, disc golf and more.
```

## Only reads (3)

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

### `compare_apps`

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

Description, as the server wrote it:

```untrusted-server-text
Sourced side-by-side comparison of Catch of a Lifetime with another app (Tinder, Bumble, Hinge, Meetup, Strava, AllTrails, Timeleft, 222, Grass, BunchUps), including where the other app is the better choice. Omit competitor to list every comparison.
```

### `get_waitlist_link`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the link to join the Catch of a Lifetime waitlist (free for founding members), optionally crediting a friend's referral code. The person signs up themselves on the page; this tool does not collect email addresses.
```

### `metro_launch_status`

- The name "metro_launch_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Live Catch of a Lifetime waitlist progress: how many people have joined in a metro versus the number needed to open it there. Omit metro for all tracked metros.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `catch-of-a-lifetime`:

```json
{
  "permissions": {
    "allow": [
      "mcp__catch-of-a-lifetime__metro_launch_status",
      "mcp__catch-of-a-lifetime__compare_apps",
      "mcp__catch-of-a-lifetime__get_waitlist_link"
    ],
    "ask": [
      "mcp__catch-of-a-lifetime__plan_outdoor_outing",
      "mcp__catch-of-a-lifetime__conditions_check",
      "mcp__catch-of-a-lifetime__draft_outing",
      "mcp__catch-of-a-lifetime__outing_promo_kit",
      "mcp__catch-of-a-lifetime__move_from_meetup"
    ],
    "deny": []
  }
}
```

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

- `mcp__catch-of-a-lifetime__plan_outdoor_outing`: untrusted-input
- `mcp__catch-of-a-lifetime__conditions_check`: untrusted-input
- `mcp__catch-of-a-lifetime__draft_outing`: untrusted-input

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 5 tools that change things (5 write). Whether a call also works without credentials was not tested: tools are never called.
