## 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__human-design__astroway_mcp_ai_chat` `mcp__human-design__astroway_mcp_ai_comparison_coach` `mcp__human-design__astroway_mcp_ai_explain_aspect` `mcp__human-design__astroway_mcp_ai_explain_transit` `mcp__human-design__astroway_mcp_multi_chart_context` `mcp__human-design__astroway_mcp_streaming` `mcp__human-design__astroway_mcp_tools_list` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__human-design__astroway_cost_estimate` |

## Findings

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

```untrusted-server-text
The server marks "astroway_mcp_multi_agent_coordinate" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

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

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

```untrusted-server-text
The server marks "astroway_mcp_tool_call_stream" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

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


## Changes things (17)

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

### `astroway_agent_tools`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Tool definitions for an agent framework, generated from the live OpenAPI document, so the schema a model fills is the schema the endpoint validates. `format=openai` (default) returns `{ type, function }` objects you can spread straight into a chat completion; `format=anthropic` returns `{ name, description, input_schema }`. The objects carry nothing of ours: how to call each tool lives in a separate `executors` map keyed by tool name, because an unexpected key inside a vendor tool object is a 400 at their end.

[Cost: see your plan — endpoint not in the public credit manifest]
```

### `astroway_cost_estimate`

- 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.
