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

| 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__ab500-research__compare_project_prices` `mcp__ab500-research__find_acquisition_opportunities` `mcp__ab500-research__get_abx_service_info` `mcp__ab500-research__get_artwork` `mcp__ab500-research__get_otdh_methodology` `mcp__ab500-research__list_artist_collector_tdh` `mcp__ab500-research__prepare_artwork_display` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.
