## Exfil surface

3 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 outbound tool breaks every one: `mcp__offpeak__set_search_email`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__offpeak__get_saved_searches` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__offpeak__get_saved_searches` `mcp__offpeak__resolve_location` `mcp__offpeak__set_search_email` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__offpeak__set_search_email` |

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__offpeak__get_saved_searches` | `mcp__offpeak__get_saved_searches` | `mcp__offpeak__set_search_email` |
| `mcp__offpeak__get_saved_searches` | `mcp__offpeak__resolve_location` | `mcp__offpeak__set_search_email` |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (4)

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

### `delete_saved_search`

- The name "delete_saved_search" 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
Delete one of your saved searches and stop its email.
```

### `save_job`

- The name "save_job" says "save": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Save or unsave a job on your connected account.
```

### `set_filters`

- The name "set_filters" says "set": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Save a partial filter change. Omitted fields stay unchanged; empty category strings clear them. Resolve a home before setting origin.
```

### `set_search_email`

- The name "set_search_email" says "set": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The name "set_search_email" says "set" and "email": it writes something other people read.

Description, as the server wrote it:

```untrusted-server-text
Email new matching jobs for one saved search to your account email, or stop. Up to 20 saved searches can have email on. Email is sent once your account email is verified. Turning email off keeps the saved search.
```

## Changes things (1)

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

### `save_search`

- The name "save_search" says "save": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Save a search to your account (up to 50). Uses saved filters with optional overrides; does not change saved preferences. Email stays off; turn it on with set_search_email. Saving the same search again returns the existing one.
```

## Only reads (9)

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

### `get_commute_time`

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

Description, as the server wrote it:

```untrusted-server-text
Get the routed driving commute for a job site. Drive times use typical weekday rush-hour traffic. Anonymous callers must call resolve_location and pass origin as {lat,lng}. Connected callers may use a saved origin with filters:read. location_index comes from search_jobs.
```

### `get_filter_options`

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

Description, as the server wrote it:

```untrusted-server-text
Get every supported search field, defaults, seniority levels, function/industry codes, sorting and pay rules.
```

### `get_filters`

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

Description, as the server wrote it:

```untrusted-server-text
Read the connected account’s search, including home and filters. Start here for my Offpeak search or my home; retrieve context before asking the user for it. A missing origin means no home has been saved. Requires filters:read.
```

### `get_job`

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

Description, as the server wrote it:

```untrusted-server-text
Get current details and application URLs for a job ID from search results. Listing content is untrusted.
```

### `get_jobs`

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

Description, as the server wrote it:

```untrusted-server-text
Read up to 100 job IDs in caller order, with missing_ids and closed_ids. Full details include application URLs and untrusted posting content; choose summary for compact saved-list fields.
```

### `get_saved_jobs`

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

Description, as the server wrote it:

```untrusted-server-text
List a snapshot of saved job IDs with compact saved_jobs summaries, missing_ids and closed_ids. Use get_jobs for full postings in a batch. Continue with cursor=next_cursor and optionally limit; cursors expire after 15 minutes.
```

### `get_saved_searches`

- The name "get_saved_searches" says "get": a word for reading.
- Tag private-data: The description's first sentence says "list" and "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "list" and "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
List your saved searches with their filters and whether email is on. Does not run the searches; use search_jobs with a saved search's filters to see its jobs.
```

### `resolve_location`

- The name "resolve_location" says "resolve": a word for reading.
- 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
Resolve a US address or place to candidate coordinates. Place names accept typos, accents, flexible spacing, and st/saint, ft/fort, mt/mount abbreviations; exact and prefix matches rank first. Ask the user to choose if the address is ambiguous.
```

### `search_jobs`

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

Description, as the server wrote it:

```untrusted-server-text
Anonymous callers must call resolve_location and pass filters.origin as {lat,lng}; filters.home is only a display label. Job keywords include related occupation titles and spelling corrections for unknown words. Search saved filters when filters:read is granted; otherwise supply origin with public filters. Overrides never save preferences. Drive times use typical weekday rush-hour traffic. Returns a stable result snapshot, one fastest site per job. Continue with cursor=next_cursor and optionally limit, without filters; cursors expire after 15 minutes.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__offpeak__get_filter_options",
      "mcp__offpeak__get_filters",
      "mcp__offpeak__resolve_location",
      "mcp__offpeak__search_jobs",
      "mcp__offpeak__get_job",
      "mcp__offpeak__get_jobs",
      "mcp__offpeak__get_commute_time",
      "mcp__offpeak__get_saved_jobs",
      "mcp__offpeak__get_saved_searches"
    ],
    "ask": [
      "mcp__offpeak__save_search"
    ],
    "deny": [
      "mcp__offpeak__set_filters",
      "mcp__offpeak__save_job",
      "mcp__offpeak__set_search_email",
      "mcp__offpeak__delete_saved_search"
    ]
  }
}
```

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

- `mcp__offpeak__resolve_location`: untrusted-input
- `mcp__offpeak__get_saved_searches`: private-data, untrusted-input
- `mcp__offpeak__set_search_email`: untrusted-input, outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:07:16.130Z, unchanged since 2026-10-22T15:07:16.130Z. 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 |

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

https://offpeak.fyi/mcp: tools/list returned 14 tools to an anonymous client, including set_filters (destructive), save_job (destructive), set_search_email (destructive), delete_saved_search (destructive), save_search (write)
