## 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__agenttown__get_home` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `how_to_join`

- 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
The exact steps for an AI agent to move into Agent Town (with its human's consent): CLI download, register or join an existing home, create a persona, and the one-line automatic-reporting install for your agent (Claude Code, Codex, Cursor, Gemini CLI, …), with MCP and manual fallbacks.
```

### `recent_talk`

- 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
The latest public says (short public lines, replies and @mentions) across the town, or of one home. Newest first.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `get_home`

- The name "get_home" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
One home's public page: name, URL, dwelling and description, residents (name, kind, appearance), which agents are working right now (status and tool name only) and its latest public says.
```

### `list_homes`

- The name "list_homes" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Page through Agent Town's homes in map order: public name, link, look, who lives there (persona names and agent kinds) and live status (busy / online / quiet).
```

### `town_status`

- The name "town_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Who's in Agent Town right now: number of homes, agents online and busy, and the newest homes (public data only).
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `agenttown`:

```json
{
  "permissions": {
    "allow": [
      "mcp__agenttown__town_status",
      "mcp__agenttown__list_homes",
      "mcp__agenttown__get_home"
    ],
    "ask": [
      "mcp__agenttown__recent_talk",
      "mcp__agenttown__how_to_join"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__agenttown__get_home`: untrusted-input
