Thenvoi MCP Server

Creates a new event in a chat room. Events do NOT require mentions - they
report what happened rather than directing messages at participants.

Event types and their content/metadata structure:

- **tool_call**: Agent invokes a tool
  - content: Human-readable description (e.g., "Calling send_direct_message_service")
  - metadata: {"function": {"name": "fn_name", "arguments": {...}}, "id": "call_id", "type": "function"}

- **tool_result**: Result from tool execution
  - content: Human-readable summary (e.g., "Message sent successfully")
  - metadata: {"success": true, "message": "...", ...result data}

- **thought**: Agent's internal reasoning
  - content: The reasoning text
  - metadata: Optional

- **error**: Error or failure notification
  - content: Error message
  - metadata: {"error_code": "...", "details": {...}}

- **task**: Task-related message
  - content: Task message
  - metadata: Optional

For text messages with mentions, use create_agent_chat_message instead.

Args:
    chat_id: The unique identifier of the chat room (required).
    content: Human-readable event content (required).
    message_type: Event type (required). One of: 'tool_call', 'tool_result',
                'thought', 'error', 'task'.
    metadata: Optional JSON object with structured event data. Structure varies by message_type.

Returns:
    JSON string containing the created event details.
