## 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__pingroom__activate_agent_inbox` `mcp__pingroom__ask_question` `mcp__pingroom__broadcast` `mcp__pingroom__cancel_question` `mcp__pingroom__create_handoff` `mcp__pingroom__create_public_room` `mcp__pingroom__join_room` `mcp__pingroom__live_status` `mcp__pingroom__request_approval` `mcp__pingroom__trigger_quick_action` `mcp__pingroom__update_quick_action` `mcp__pingroom__update_quick_actions` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__pingroom__broadcast` `mcp__pingroom__trigger_quick_action` |

### `cancel_question`

- The name "cancel_question" says "cancel": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Withdraw a still-pending question you asked.
```

### `delete_attachment`

- The name "delete_attachment" says "delete": a word for removing or ending something.

- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Delete an incoming webhook (by id) from a room the account owns.
```

### `disconnect`

- The description's first verb is "revoke": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Revoke this authenticated robot connection, including its access and refresh credentials and room memberships. Use only when the human explicitly requests logout, disconnection, or reconnection. Call BEFORE clearing local credentials or running MCP logout/login. It affects only the current connection and accepts no account or robot selector. After login, restart or reload the MCP client, then match connection_info owner.id and handle to the approved account and robot before sending.
```

### `join_room`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Join a room using its invite code. Include the password only if the room is protected.
```

### `live_status`

- The name "live_status" says "status": a word for reading.
- The description's first verb is "start": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Start, update, or end a live progress card on the room members' lock screen (an iOS Live Activity / Android live update). Reuse the same correlation_id for every ping of one stream: the first ping starts the card and sends one alert, further "running" pings move it silently, and the first "done"/"failed" sends one completion alert and ends it. Free accounts get a small number of NEW streams per day; updates and the final ping of an open stream are never charged; a first ping that is already "done"/"failed" counts as a new stream.
```

### `rotate_handle`

- The name "rotate_handle" says "handle": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Rotate this agent's public handle — kill-switch for a leaked handle.
```

### `set_avatar`

- The name "set_avatar" says "set": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Set this agent's avatar. Must be one of the PingRoom bot avatars.
```

### `update_quick_action`

- The name "update_quick_action" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Configure a numbered quick-action slot for a room the account owns. Sends a background room refresh to room members' devices.
```

### `update_quick_actions`

- The name "update_quick_actions" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Configure several of a room's quick-action slots in one call. Prefer this over repeated update_quick_action: each single-slot write wakes room members' devices with its own background refresh, so setting up four Pings one at a time spends four of a finite daily push budget on one operation. Slots you do not list are left exactly as they are, so this is also the right tool for editing a single Ping.
```

### `update_webhook`

- The name "update_webhook" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Update an incoming webhook (by id) on a room the account owns — e.g. change its icon, title, message, or sound.
```

## Can't be undone (1)

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

### `broadcast`

- The name "broadcast" says "broadcast": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The name "broadcast" says "broadcast": it sends or publishes something to other people. The input takes a URL (input.data.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Send a custom ping to a room the account belongs to. Pass data.checklist.items to send a checklist the room ticks through together; read the ticks back as checklist_state. Rate-limited. In someone else's personal room only a Pro account may send it, text only (a link in the message is refused too), without title, is_urgent or requires_ack (all three are ignored there), and it counts toward the visitor's two-ping cap; otherwise use trigger_quick_action there.
```

## Changes things (11)

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

### `activate_agent_inbox`

- The description's first verb is "start": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Start or resume the onboarding Question in the private room the human chose during authorization. If recipient_not_ready, ask the human to install or update PingRoom from install_url, open the app, sign in, and enable notifications before retrying. Read question.id, then call wait_for_handoff only while state is pending and within a bounded local deadline. Success is answered with activation_completed true. Any other terminal result is incomplete: stop polling that attempt, then call activate_agent_inbox again for one numbered retry. The stamp requires native phone receipt before the human answer.
```

### `ask_question`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Ask a person a question with 2-4 tappable options, then block on their answer (pair with wait_for_answer). Delivered as a push they can answer from the lock screen or in-app; the first valid answer wins. Rate-limited.
```

### `connection_info`

- 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.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Verify the current connection: owner.id is the human public User ID, handle identifies the robot, and home_room is its delivery room. After login or reconnect, match owner.id and handle to the approved account and robot before sending. A mismatch means stop and reload or restart the MCP client. Includes a credential-protected latest-pings feed and token-free install URL; never send credentials to the install URL.
```

### `create_handoff`

- The name "create_handoff" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Hand work to exactly one human as either an acknowledgement or a tappable question. The server verifies that one of the recipient's current devices supports the complete Handoff action before creating anything.
```

### `create_public_room`

- The name "create_public_room" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Create a publicly discoverable room with a unique @handle. Counts toward the free-plan five-room cap.
```

### `create_room`

- The name "create_room" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a new private room owned by the authenticated account. Free accounts may own up to five rooms. If this agent was granted every room and has no delivery room yet, the new room becomes its delivery room — where its handoffs and direct questions land.
```

### `create_webhook`

- The name "create_webhook" says "create": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Create an incoming webhook for a room the account owns. The bound account must be Pro. Returns the secret trigger URL — treat it as a credential.
```

### `request_approval`

- The name "request_approval" says "request": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Ask the human to approve or reject an action, then block on their answer (pair with wait_for_approval). Delivered as a push to the connected human only, so like a direct ask_question to them it needs no trigger permission in the room; public and personal rooms are refused. Rate-limited.
```

### `trigger_quick_action`

- The name "trigger_quick_action" says "trigger": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.data.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Press a room quick action, notifying its members. Rate-limited. Read the action's input_type first (list_quick_actions): location needs data.location, link needs data.url, file/photo/pdf need attachment_ids — a press without the matching detail is a 422 quick_action_input_required. In someone else's personal room is_urgent and requires_ack are ignored; only the owner's own setting on the action applies.
```

### `upload_attachment`

- The name "upload_attachment" says "upload": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Upload a small file (max ~90 KiB over MCP; Pro account required) and get an attachment id to include in broadcast or ask_question via attachment_ids. Larger files: use the PingRoom CLI or agent REST API.
```

### `wait_for_handoff`

- The name "wait_for_handoff" says "wait": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Long-poll a Handoff until the human resolves it, it expires, or the bounded timeout elapses. For the onboarding Question returned by activate_agent_inbox, success requires an answered result with activation_completed true; use a bounded local deadline and treat any terminal answer without that stamp as incomplete.
```

## Only reads (18)

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

### `get_approval`

- The name "get_approval" says "get": a word for reading.

### `get_handoff`

- The name "get_handoff" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch the authoritative current state of one Handoff without blocking.

### `get_live_status`

- The name "get_live_status" says "get": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Read back the current state of a live stream you created, so a restarted producer can reconcile instead of starting a duplicate. Only returns streams started by this credential, within the last 24 hours. Returns notification_id and correlation_id, then the stored display state (state, progress, message, category, template, accent_override, eta_at, deadline_at, duration_seconds, metrics, prompt, options, left, right, center, steps, current_step), action_state, and updated_at. Fields you never set come back as null rather than being omitted, so a matchup/metrics/countdown/question stream can be resumed without re-sending content.
```

### `get_notification`

- The name "get_notification" says "get": a word for reading.

```

### `wait_for_answer`

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

Description, as the server wrote it:

```untrusted-server-text
