## Description

Check which Super Carl communication channels are available for a target before sending a message. Returns the list of channels with their `can_send` status, recipient email, and connector user IDs. Each channel entry carries verbose reason/relationship metadata — pass Fields (e.g. `channel`, `can_send`, `reason`) to keep the result small when you only need the essentials. [See the documentation](https://supercarl.ai/docs#endpoints-communications)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `targetUserId` | `string` | No | Optional Super Carl person/user UUID for the communication target, for example 550e8400-e29b-41d4-a716-446655440000. |
| `linkedinProfileUrl` | `string` | No | Optional LinkedIn profile URL for the communication target, for example https://www.linkedin.com/in/target-person/. |
| `linkedinUsername` | `string` | No | Optional LinkedIn public identifier when a full profile URL is not available, for example jane-doe-1234567. |
| `xProfileUrl` | `string` | No | Optional X profile URL for the communication target, for example https://x.com/username. |
| `xUsername` | `string` | No | Optional X username without the @ symbol, for example janedoe. |
| `instagramProfileUrl` | `string` | No | Optional Instagram profile URL for the communication target, for example https://www.instagram.com/janedoe/. |
| `instagramUsername` | `string` | No | Optional Instagram username without the @ symbol, for example janedoe. |
| `recipientEmail` | `string` | No | Recipient email address for Gmail sends, or a returned email option from Check Communication Capabilities, for example jane@example.com. |
| `channels` | `string[]` | No | Optional channels to check. Example: ["gmail_send", "linkedin_send_message"]. Omit this prop to check all supported channels. |
| `delegateUserId` | `string` | No | Optional Super Carl team-seat user ID to search as. This is the UUID of a teammate's user record that the API key owner can delegate to, for example 550e8400-e29b-41d4-a716-446655440000. |
| `fields` | `string[]` | No | Optional list of fields to return per row instead of the full record — keeps large result sets well under the context limit. Supports dot-paths for nested values, for example name, linkedin_profile_url, resolved_target.id. Omit this prop to return the API default field set (every field). |

const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)

const { tools } = await mcp.listTools()

// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({
