## 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__agent-tools__domain_lookup` `mcp__agent-tools__image_ocr` `mcp__agent-tools__url_metadata` `mcp__agent-tools__web_to_markdown` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__agent-tools__file_convert` `mcp__agent-tools__image_ocr` `mcp__agent-tools__pdf_to_text` `mcp__agent-tools__timezone_convert` `mcp__agent-tools__url_metadata` `mcp__agent-tools__web_to_markdown` |
