1//! Core Model Context Protocol types and validation
2//!
3//! This crate provides the fundamental types, traits, and validation logic
4//! for the Model Context Protocol. It serves as the foundation for building
5//! MCP servers and clients with strong type safety and validation.
6//!
7//! # Quick Start
8//!
9//! ```rust
10//! use pulseengine_mcp_protocol::{Tool, Content, CallToolResult};
11//! use serde_json::json;
12//!
13//! // Define a tool with proper schema
14//! let tool = Tool {
15//!     name: "get_weather".to_string(),
16//!     description: "Get current weather for a location".to_string(),
17//!     input_schema: json!({
18//!         "type": "object",
19//!         "properties": {
20//!             "location": {
21//!                 "type": "string",
22//!                 "description": "City name or coordinates"
23//!             }
24//!         },
25//!         "required": ["location"]
26//!     }),
27//! };
28//!
29//! // Create a tool response
30//! let result = CallToolResult {
31//!     content: vec![Content::text("Current weather: 22°C, sunny".to_string())],
32//!     is_error: Some(false),
33//! };
34//! ```
35//!
36//! This crate is currently used in production by the Loxone MCP Server
37//! for home automation with 30+ tools.
