## Exfil surface

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

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

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__hai-agents__list_files` | `mcp__hai-agents__list_files` | `mcp__hai-agents__send_message` |
| `mcp__hai-agents__list_files` | `mcp__hai-agents__read_file` | `mcp__hai-agents__send_message` |
| `mcp__hai-agents__read_file` | `mcp__hai-agents__list_files` | `mcp__hai-agents__send_message` |
| `mcp__hai-agents__read_file` | `mcp__hai-agents__read_file` | `mcp__hai-agents__send_message` |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `cancel_session`

- The name "cancel_session" says "cancel": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
Cancel a session; a no-op if it does not exist or already finished.
```

## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `send_message`

- The name "send_message" says "send": a word for sending, and what is sent cannot be taken back.
- Tag outbound: The name "send_message" says "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Send a follow-up message to a running session.
```

## Changes things (3)

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

### `run_agent`

- The name "run_agent" says "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start an agent on a task; return the answer or a session handle to wait on.

``agent`` is a name from list_agents, which runs its latest revision, or ``name:N`` to run revision N.
```

### `share_session`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Make a session publicly readable and return its absolute share URL.
```

### `write_file`

- The name "write_file" says "write": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Write base64-encoded content to a file on a browser session's machine.

``session_id`` is the browser session id issued by env-manager when the session was
created, not the id ``run_agent`` returns.
```

## Only reads (4)

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

### `list_agents`

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

Description, as the server wrote it:

```untrusted-server-text
List agents the caller can run: their org's agents plus the public ``h/`` ones.
```

### `list_files`

- The name "list_files" says "list": a word for reading.
- Tag private-data: The name "list_files" says "list" and "file": it reads files. The description's first sentence says "list" and "file": it reads files.
- Tag untrusted-input: The description's first sentence says "list" and "browser": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
List files on a browser session's machine (e.g. downloads), newest first.

``session_id`` is the browser session id issued by env-manager when the session was
created, not the id ``run_agent`` returns.

When a listing is truncated, page on the last entry's modified_at (ISO-8601)
and name, passed as modified_before and name_after. Send both: modification
times are not unique, and a timestamp alone skips the rest of a tied group.
```

### `read_file`

- The name "read_file" says "read": a word for reading.
- Tag private-data: The name "read_file" says "read" and "file": it reads files. The description's first sentence says "read" and "file": it reads files.
- Tag untrusted-input: The description's first sentence says "read" and "browser": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Read a file from a browser session's machine; returns base64 content and metadata.

``session_id`` is the browser session id issued by env-manager when the session was
created, not the id ``run_agent`` returns.
```

### `wait_for_session`

- The name "wait_for_session" says "wait": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Poll a session: with ``wait`` long-poll for the answer, else return the current snapshot.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `hai-agents`:

```json
{
  "permissions": {
    "allow": [
      "mcp__hai-agents__wait_for_session",
      "mcp__hai-agents__list_agents",
      "mcp__hai-agents__list_files",
      "mcp__hai-agents__read_file"
    ],
    "ask": [
      "mcp__hai-agents__run_agent",
      "mcp__hai-agents__send_message",
      "mcp__hai-agents__share_session",
      "mcp__hai-agents__write_file"
    ],
    "deny": [
      "mcp__hai-agents__cancel_session"
    ]
  }
}
```

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

- `mcp__hai-agents__send_message`: outbound
- `mcp__hai-agents__list_files`: private-data, untrusted-input
- `mcp__hai-agents__read_file`: private-data, untrusted-input
