Module mcp 

MCP (Model Context Protocol) server domain types.

These types represent MCP servers in the system, independent of any infrastructure concerns (database, process management, etc.).

Design

• McpServer - A persisted MCP server with ID
• NewMcpServer - An MCP server to be inserted (no ID yet)
• McpServerConfig - Execution configuration (exe_path, args, URL, path_extra)
• McpServerType - Connection type (stdio or SSE)
• McpServerStatus - Runtime status (stopped, starting, running, error)
• McpLifecycle - Startup lifecycle policy (eager, lazy, manual)
• McpEnvEntry - Environment variable entry
• McpTool - Tool exposed by an MCP server
• McpToolResult - Result of a tool invocation
• ToolIndex / ToolSummary - Progressive-disclosure tool registry index
