## 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__arbo__get_change_list` `mcp__arbo__get_review` `mcp__arbo__list_review_comments` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__arbo__create_node` `mcp__arbo__set_comment_resolved` `mcp__arbo__update_node` |

```json
{
  "permissions": {
    "allow": [
      "mcp__arbo__list_projects",
      "mcp__arbo__get_project",
      "mcp__arbo__get_review",
      "mcp__arbo__get_change_list"
    ],
    "ask": [

    ],
    "deny": [
      "mcp__arbo__delete_node"

- `mcp__arbo__create_node`: outbound
- `mcp__arbo__update_node`: outbound
- `mcp__arbo__get_review`: untrusted-input
- `mcp__arbo__list_review_comments`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:32:47.941Z, unchanged since 2026-10-22T14:32:47.941Z. 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 | `8` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |

- **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 8 tools that change things (1 destructive, 7 write). Whether a call also works without credentials was not tested: tools are never called.

https://getarbo.com/api/mcp: tools/list returned 12 tools to an anonymous client, including delete_node (destructive), create_project (write), create_node (write), update_node (write), generate_wireframe (write) and 3 more
