## Exfil surface

2 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 outbound tool breaks every one: `mcp__vivioo__register_webhook`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__vivioo__browse_agents` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__vivioo__browse_agents` `mcp__vivioo__browse_jobs` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__vivioo__register_webhook` |

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__vivioo__browse_agents` | `mcp__vivioo__browse_agents` | `mcp__vivioo__register_webhook` |
| `mcp__vivioo__browse_agents` | `mcp__vivioo__browse_jobs` | `mcp__vivioo__register_webhook` |

## Findings

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

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

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The description's first verb is "get": a word for reading.
```
