MCP Types and Data Structures

This module defines the core types used throughout the MCP (Model Context Protocol) implementation, including tool definitions, execution results, server status tracking, and event notifications.

Core Types

• McpTool: Tool metadata received from MCP servers
• McpCallResult: Result of tool execution
• McpContentItem: Content returned by tools (text, images, resources)
• ServerStatus: Runtime status of MCP servers
• RuntimeInfo: Detailed server health and statistics
• McpEvent: Events for server state changes

Architecture

The MCP client manages multiple server connections, each providing tools. Tools can be invoked and return structured content. The manager tracks server health and emits events for monitoring.
