| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__kinde__kinde_list_users` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:29:34.768Z, unchanged since 2026-10-22T15:29:34.768Z. 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 | `6` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not 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 6 tools that change things (6 destructive). Whether a call also works without credentials was not tested: tools are never called.

https://kinde.usefulapi.io/mcp: tools/list returned 23 tools to an anonymous client, including kinde_create_organization (destructive), kinde_add_users_to_organization (destructive), kinde_grant_user_role_in_organization (destructive), kinde_grant_user_permission_in_organization (destructive), kinde_create_role (destructive) and 1 more
