## Exfil surface

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

| Tag | Meaning | Tools |

| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__homerun__homerun_get_application` `mcp__homerun__homerun_list_notes` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__homerun__homerun_add_note` `mcp__homerun__homerun_get_application` `mcp__homerun__homerun_get_vacancy` `mcp__homerun__homerun_list_application_tags` `mcp__homerun__homerun_list_applications` `mcp__homerun__homerun_list_notes` `mcp__homerun__homerun_list_tags` `mcp__homerun__homerun_list_vacancies` `mcp__homerun__homerun_move_application_to_stage` |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

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

### `homerun_move_application_to_stage`

- The name "homerun_move_application_to_stage" says "move": 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.

Description, as the server wrote it:

```untrusted-server-text
WRITE: move ONE application to another hiring stage of its vacancy (PATCH with only the stage id; nothing else on the application changes). Get stage ids from homerun_get_vacancy. Homerun's own automations for that stage may run (for example automatic e-mails configured in Homerun); this tool sends no e-mail itself and does not reject or delete anyone. PATCH /job-applications/{job_application_id} (scope job-applications:write).
```

## Changes things (1)

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

### `homerun_add_note`

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

Description, as the server wrote it:

```untrusted-server-text
WRITE: add ONE note (1-2000 characters) to one application. It becomes visible to the hiring team in Homerun and cannot be removed with this server. display_name is free text shown as the author.

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:29:15.665Z, unchanged since 2026-10-22T15:29:15.665Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

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

https://homerun.usefulapi.io/mcp: tools/list returned 9 tools to an anonymous client, including homerun_move_application_to_stage (destructive), homerun_add_note (write)
