**8 tools: 1 can delete or cancel things, 3 change things and 4 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 1 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 3 | ask |

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

## Findings

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

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

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


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `delete_watch`

- The name "delete_watch" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Stop monitoring. Frees one of your watch slots. Delete watches you no longer need.
```

## Changes things (3)

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

### `ack_changes`

- The description's first verb is "mark": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Mark changes up to a cursor as processed. Use with get_changes(peek=true) for at-least-once delivery: peek, act on the changes, then ack the cursor get_changes returned. Not needed if you call get_changes without peek (that acknowledges automatically).
```

### `get_changes`

- The name "get_changes" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Return job changes detected since your last get_changes call, across all your watches or one watch. This is the cheap replacement for re-browsing careers pages: if it returns an empty list, nothing you care about has changed. By default the cursor advances so each change is delivered once; pass peek=true to look without advancing, or since=<cursor> to replay.
```

### `watch_jobs`

- The description's first verb is "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- 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
Create a persistent watch for tech jobs. Describe what you want in query ("iOS jobs in Austin making at least 150k a year with a maximum of 6 years of experience") and leave url out: the watch then covers every job board Watchtower monitors (tech companies and startups, whatever platform they use) and reports each new matching posting (JOB_ADDED). The response shows how the query was read (interpreted), the jobs open right now that match (current_jobs) and how many boards are covered (coverage); later call get_changes for new ones. Use this INSTEAD OF re-running job searches or re-checking careers pages yourself. To follow one company, or to cover a company the directory is missing, pass url (or urls for several): Greenhouse, Lever, Ashby, Workable, SmartRecruiters, Recruitee, Workday, iCIMS, Oracle Recruiting, Eightfold and SuccessFactors boards, and the Apple, Google, Amazon and Microsoft careers sites, are read through their own endpoints; other careers pages are parsed via schema.org JobPosting JSON-LD. A careers page that only links to a supported board is watched through that board (resolved_from says so); a page with neither is rejected with NO_JOB_DATA. A board you watch stays covered for every search watch. A board watch emits JOB_ADDED / JOB_REMOVED / JOB_UPDATED. Jobs carry title, location, other_locations, department, company, url, posted_at, remote, seniority, and salary / experience_years when the posting states them. Explicit filters override what the query says.
```

## Only reads (4)

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

### `get_watch`

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

Description, as the server wrote it:

```untrusted-server-text
Get a watch with its status and the jobs currently open that match its filters: on its board, or across every monitored board for a watch created without a url. Use this to answer "what is open right now" without searching or fetching careers pages yourself.
```

### `list_companies`

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

Description, as the server wrote it:

```untrusted-server-text
List the companies whose job boards Watchtower monitors, i.e. what search_jobs and watch_jobs without a url cover. Pass query to check whether a company is covered ("stripe"). Each entry has name, board_url (pass it to watch_jobs as url to follow only that company), platform and open_jobs. Read-only, no token needed. If a company is missing, watch its board URL or careers page to add it.
```

### `list_watches`

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

Description, as the server wrote it:

```untrusted-server-text
List all active watches for your client with their health, last check time and number of pending (undelivered) changes.
```

### `search_jobs`

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

Description, as the server wrote it:

```untrusted-server-text
Find the tech jobs open right now that match a request, across every job board Watchtower monitors (tech companies and startups). Describe what you want in query ("iOS jobs in Austin with a maximum of 6 years of experience"). Read-only: nothing is saved and no watch is created, and no token is needed. The response shows how the query was read (interpreted), the matching jobs newest first, the total, and next_offset for the next page. Use this for "what is open right now"; to be told about new postings later, use watch_jobs instead. Jobs carry title, location, other_locations, department, company, url, posted_at, remote, seniority, and salary / experience_years when the posting states them. Explicit filters override what the query says.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__watchtower__search_jobs",
      "mcp__watchtower__list_companies",
      "mcp__watchtower__list_watches",
      "mcp__watchtower__get_watch"
    ],
    "ask": [
      "mcp__watchtower__watch_jobs",
      "mcp__watchtower__get_changes",
      "mcp__watchtower__ack_changes"
    ],
    "deny": [
      "mcp__watchtower__delete_watch"
    ]
  }
}
```

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

- `mcp__watchtower__watch_jobs`: untrusted-input, outbound
- `mcp__watchtower__get_watch`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:09:57.905Z, unchanged since 2026-10-22T15:09:57.905Z. 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 | `4` |

- **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 4 tools that change things (1 destructive, 3 write). Whether a call also works without credentials was not tested: tools are never called.

https://watchtower.lat/mcp?ref=registry: tools/list returned 8 tools to an anonymous client, including delete_watch (destructive), watch_jobs (write), get_changes (write), ack_changes (write)
