## Exfil surface

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

| 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__agent-tools__is-phone-e164` `mcp__agent-tools__is-url-safe` |

- **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 32 tools that change things (1 destructive, 31 write). Whether a call also works without credentials was not tested: tools are never called.

https://agent-tools-mcp.yvan11.workers.dev/mcp: tools/list returned 32 tools to an anonymous client, including minify-html (destructive), is-card-safe (write), is-email-safe (write), is-iban-safe (write), is-iso-date-safe (write) and 27 more
