## 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__githubcard__get_card_design` `mcp__githubcard__get_template_design` `mcp__githubcard__list_components` `mcp__githubcard__list_templates` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__githubcard__create_card` `mcp__githubcard__delete_card` `mcp__githubcard__get_card_design` `mcp__githubcard__get_template_design` `mcp__githubcard__get_usage` `mcp__githubcard__list_cards` `mcp__githubcard__list_components` `mcp__githubcard__list_palettes` `mcp__githubcard__list_templates` `mcp__githubcard__validate_card` |
