## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| 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__argos-cts-bridge-lookup__lookup_ownerless_bridge` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `lookup_ownerless_bridge` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "lookup_ownerless_bridge" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "lookup_ownerless_bridge" says "lookup": a word for reading.
```


## Changes things (1)

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

### `lookup_ownerless_bridge`

- The name "lookup_ownerless_bridge" says "lookup": a word for reading.

- 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
Costs 0.007 USDC on Arc per lookup. Inspect an original or wrapped token on Arc or Base using Circle CTS, CrossChainTokenService and CCTP. Returns token roles, counterpart addresses, wrapped supply, contract checks and block evidence. No bridge execution. A missing bridge is a valid paid result. Requires an x402-capable client; never request private keys.
```
