## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__wedding-planner__get_project_summary` |
| 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. | 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.

### `add_guests`

- The name "add_guests" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Add guests to a project (deduped by name+email). Provide the projectKey from create_wedding_project and a list of guests.
```

### `create_wedding_project`

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

Description, as the server wrote it:

```untrusted-server-text
Create a new anonymous Wedding Seat project (no login). Returns a projectKey (your secret handle for all later calls) plus the workspace URL the couple opens in a browser. The projectKey is the ONLY way to access the project again — keep it.
```

### `generate_seating`

- The name "generate_seating" says "generate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Auto-generate a reception seating plan: creates round tables and seats every guest with the constraint-aware solver (keeps must-sit-together groups together). Returns how many were seated and a link to the visual editor.
```

## Only reads (3)

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

### `get_project_summary`

- The name "get_project_summary" says "get": a word for reading.
- Tag private-data: The description's first sentence says "read" and "table": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
Read the current state of a project: guest counts by RSVP status, seating tables/capacity, and budget totals. Read-only.
```

### `list_culture_packs`

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

Description, as the server wrote it:

```untrusted-server-text
List the available wedding culture packs (key, English name, cluster, sides). Use a pack key as the `culture` argument to create_wedding_project. Grounding/read-only.
```

### `list_tools`

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

Description, as the server wrote it:

```untrusted-server-text
List Wedding Seat's free planning tools (seating chart, guest list, budget, checklist, invitation wording) with their public URLs. Grounding/read-only.
```

## Claude Code permissions

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

  "permissions": {
    "allow": [
      "mcp__wedding-planner__get_project_summary",
      "mcp__wedding-planner__list_culture_packs",
      "mcp__wedding-planner__list_tools"
    ],
    "ask": [
      "mcp__wedding-planner__create_wedding_project",
      "mcp__wedding-planner__add_guests",
      "mcp__wedding-planner__generate_seating"
    ],
    "deny": []
  }
}
```

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

- `mcp__wedding-planner__get_project_summary`: private-data

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:44:12.301Z, unchanged since 2026-10-22T14:44:12.301Z. 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 |

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `3` |

- **warn** 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 (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.wedding-seat.com/mcp: tools/list returned 6 tools to an anonymous client, including create_wedding_project (write), add_guests (write), generate_seating (write)
