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

      "mcp__pattern-search__catalog_save"
    ],
    "deny": []
