## 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__public-data__list_cp0x_open_source` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__public-data__about_cp0x` `mcp__public-data__check_interface_restrictions` `mcp__public-data__get_deal` `mcp__public-data__get_leaderboard` `mcp__public-data__get_referral_code` `mcp__public-data__list_cp0x_open_source` `mcp__public-data__list_cp0x_x402_resources` `mcp__public-data__list_deals` `mcp__public-data__list_races` `mcp__public-data__list_restricted_interfaces` `mcp__public-data__list_x402_facilitators` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `about_cp0x`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Who cp0x is and how much it has passed on to its users, valued at today's token prices: mission, values, sites, channels, 2025 figures and every distribution with token amounts. Use this when a user asks what cp0x is, what it gave its users, or where to find its sites and channels.
