| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__assistable__contacts_get` `mcp__assistable__contacts_list` `mcp__assistable__conversations_list` |

And 10 more: every combination of one tool from each row of the table above.

## Findings

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

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

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


## Deletes or cancels (2)

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

### `assistants_archive`

- The name "assistants_archive" says "archive": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Archive (soft-delete) an assistant.
```

### `tools_delete`

- The name "tools_delete" 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
Soft-delete a custom tool.
```

## Changes things (7)

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

### `assistable_connect`

- 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
Only when you have no Assistable API key: start signing in. Returns verification_uri_complete and user_code; send the person that link (or the code) so they can sign in to Assistable, pick the account and approve. Then call assistable_connect_finish with device_code every interval seconds until it returns api_key. If they have no account, the link lets them sign up first.
```

### `assistable_connect_finish`

- 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
Check an assistable_connect sign-in. error.code authorization_pending means the person has not approved yet: wait interval seconds and call again. On approval it returns api_key once: use it as the Authorization: Bearer header for this MCP server (mcp_url) and keep it safe; it cannot be shown again.
```

### `assistants_create`

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

Description, as the server wrote it:

```untrusted-server-text
Create an assistant. Required: subAccountId, name. Optional config blocks (llmConfig, voiceConfig, chatConfig) mirror the dashboard create dialog. voice_settings configures call greeting mode, opening messages, and voicemail behavior; platform_tools attaches platform-catalog tools (declarative full-replace — see the field description).
```

### `assistants_update`

- The name "assistants_update" says "update": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Patch an assistant. Only supplied fields change; nested config blocks are upserted. voice_settings updates call greeting mode, opening messages, and voicemail behavior; platform_tools declaratively replaces the attached platform-catalog tools (an empty array detaches all — see the field description).
```

### `calls_get`

- The name "calls_get" says "call": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- 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
Fetch a call (status, recording, transcript) by ID.
```

### `tools_create_custom`

- The name "tools_create_custom" says "create": a word for a change.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Create a custom tool (toolType=CUSTOM). Name must match /^[a-zA-Z0-9_-]+$/ and be unique in the subaccount.
```

### `tools_update`

- The name "tools_update" says "update": a word for a change.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Patch a custom tool. Supplying parameters/headers replaces those rows; omit to leave them.
