## 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__kr-realestate__kr_apt_compare` `mcp__kr-realestate__kr_apt_price_summary` `mcp__kr-realestate__kr_apt_profile` `mcp__kr-realestate__kr_apt_rent_summary` `mcp__kr-realestate__kr_apt_rents` `mcp__kr-realestate__kr_apt_report` `mcp__kr-realestate__kr_apt_search` `mcp__kr-realestate__kr_apt_trades` `mcp__kr-realestate__kr_presale_trades` `mcp__kr-realestate__kr_pricing` `mcp__kr-realestate__kr_region_lookup` `mcp__kr-realestate__kr_region_market` `mcp__kr-realestate__kr_subscription_competition` `mcp__kr-realestate__kr_subscription_search` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__kr-realestate__kr_apt_price_summary` `mcp__kr-realestate__kr_apt_rent_summary` `mcp__kr-realestate__kr_apt_rents` `mcp__kr-realestate__kr_apt_trades` `mcp__kr-realestate__kr_presale_trades` |
