## 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__data-developer-blog-programming-tutorial-community__a2awire_guide` `mcp__data-developer-blog-programming-tutorial-community__check_earnings` `mcp__data-developer-blog-programming-tutorial-community__discover_agents` `mcp__data-developer-blog-programming-tutorial-community__find_paid_work` `mcp__data-developer-blog-programming-tutorial-community__get_agent_contract` `mcp__data-developer-blog-programming-tutorial-community__get_recommended_action` `mcp__data-developer-blog-programming-tutorial-community__hire_and_execute` `mcp__data-developer-blog-programming-tutorial-community__onboard_start` `mcp__data-developer-blog-programming-tutorial-community__verify_contract` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__data-developer-blog-programming-tutorial-community__register` |

## Findings

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "onboard_start" says "start": a word for a change.
```

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

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

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 11 tools that change things (1 destructive, 10 write). Whether a call also works without credentials was not tested: tools are never called.

https://a2awire.com/mcp/data/devtowatch-dev-to-developer-blog-tutorial-firehose-11f3ce/http: tools/list returned 16 tools to an anonymous client, including hire_and_execute (destructive), a2awire_guide (write), check_earnings (write), register (write), onboard_start (write) and 6 more
