Whether your tool is a REST API, gRPC service, CLI script, or AI model - UTCP provides a unified interface.\n\n**Key Principles:**\n- ✅ No wrapper tax - tools work as-is\n- ✅ Protocol agnostic - HTTP, WebSocket, CLI, anything\n- ✅ AI-friendly - designed for LLM tool calling\n- ✅ Secure by default - preserves existing security\n- ✅ Scalable - from local scripts to distributed systems\n\n## 🎯 Why .NET 10?\n\nThis implementation leverages .NET 10's cutting-edge features:\n\n| Feature | Benefit |\n|---------|---------|\n| **Native AOT** | 10x faster startup, minimal memory (141MB typical) |\n| **Cross-platform** | Same binary runs on Linux, Windows, macOS |\n| **Modern async** | Native async/await, perfect for I/O-bound tools |\n| **Type safety** | Strong typing prevents runtime errors |\n| **Performance** | Near-zero CPU idle, instant response under load |\n\n**Real-world performance:**\n- Memory: ~141MB\n- CPU (idle): 0%\n- CPU (4+ hours): 20 seconds total\n- Startup: \u003c100ms\n\n## 📦 What's Included\n\n### Core Modules\n\n| Module | Description | Status |\n|--------|-------------|--------|\n| **UTCP.Core** | Core models and interfaces | ✅ Complete |\n| **UTCP.CLI** | Command-line tool interface | ✅ Complete |\n| **UTCP.Auth** | Authentication (API key, Basic, OAuth2) | ✅ Complete |\n| **UTCP.Repository** | Tool repository management | ✅ Complete |\n| **UTCP.Tools** | Tool definitions and search | ✅ Complete |\n| **UTCP.Helpers** | Utility functions | ✅ Complete |\n| **UTCP.Transports** | Transport layer implementations | ✅ Complete |\n\n### Transport Examples (15+)\n\nAll transport types from the official spec:\n\n- ✅ **HTTP/HTTPS** - RESTful API calls\n- ✅ **WebSocket** - Real-time bidirectional\n- ✅ **Server-Sent Events (SSE)** - Server push\n- ✅ **Streamable HTTP** - Chunked responses\n- ✅ **CLI/Terminal** - Command execution\n- ✅ **Text-based** - Simple text protocols\n- ✅ **TCP/UDP** - Raw socket communication\n- ✅ **gRPC** - High-performance RPC\n- ✅ **GraphQL** - Query-based API\n- ✅ **MCP** - Model Context Protocol\n- ✅ **WebRTC** - Peer-to-peer\n- ✅ **Ollama** - Local AI models (exclusive to .NET!)\n\n### Reference Implementation\n\nComplete UTCP server example with:\n- Multi-transport support (HTTP + WebSocket)\n- Tool calling API\n- Health endpoints\n- Production-ready deployment\n\n## 🚀 Quick Start\n\n### Prerequisites\n\n- [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)\n- (Optional) [Ollama](https://ollama.ai) for AI integration\n\n### Installation\n\n```bash\ngit clone https://github.com/barrersoftware/dotnet-utcp.git\ncd dotnet-utcp\ndotnet build\n```\n\n### Usage Examples\n\n#### 1. Ask Ollama AI\n```bash\ncd src/UTCP.CLI\ndotnet run -- --provider \"write hello world in C#\" --tool ask\n\n# Specify a model\ndotnet run -- --provider \"explain async/await\" --tool ask --model \"qwen2.5-coder:32b\"\n```\n\n#### 2. HTTP Tool Calling\n```bash\ndotnet run -- --provider \"https://api.example.com\" --tool http-get\n```\n\n#### 3. Execute CLI Commands\n```bash\ndotnet run -- --provider \"ls -la\" --tool cli-exec\n```\n\n#### 4. Run UTCP Server\n```bash\ncd examples/utcp_server\ndotnet run\n\n# Server starts on http://0.0.0.0:8787\n# Test: curl http://localhost:8787/health\n```\n\n## 🔧 Building a UTCP Service\n\n```csharp\nusing UTCP.Core.Models;\nusing UTCP.Transports;\n\nvar builder = WebApplication.CreateBuilder(args);\nbuilder.WebHost.UseUrls(\"http://0.0.0.0:8787\");\n\nvar app = builder.Build();\napp.UseWebSockets();\n\n// Initialize Ollama transport\nvar ollama = new OllamaTransport(\"http://localhost:11434\");\nawait ollama.InitializeAsync();\n\n// Define a tool\napp.MapPost(\"/call\", async (UtcpRequest request) =\u003e\n{\n    if (request.ToolName == \"ask\")\n    {\n        var response = await ollama.CallToolAsync(request);\n        return Results.Ok(response);\n    }\n    \n    return Results.BadRequest(\"Unknown tool\");\n});\n\napp.Run();\n```\n\n## 📊 Architecture\n\n```\n┌─────────────────────────────────────────────┐\n│           Application Layer                  │\n│  (Your code, AI agents, CLI tools)          │\n└─────────────────────────────────────────────┘\n                    ↓\n┌─────────────────────────────────────────────┐\n│         UTCP.Core (Models \u0026 Interfaces)      │\n│  UtcpRequest, UtcpResponse, UtcpTool        │\n└─────────────────────────────────────────────┘\n                    ↓\n┌─────────────────────────────────────────────┐\n│      UTCP.Transports (Protocol Layer)        │\n│  HTTP, WebSocket, SSE, Ollama, CLI, etc.    │\n└─────────────────────────────────────────────┘\n                    ↓\n┌─────────────────────────────────────────────┐\n│       Actual Tools (APIs, Services)          │\n│  REST APIs, gRPC, CLI scripts, AI models    │\n└─────────────────────────────────────────────┘\n```\n\n## 🎯 Use Cases\n\n### 1.
