# UTCP for .NET 🚀
**Complete .NET 10 implementation of the Universal Tool Calling Protocol (UTCP)**
[](LICENSE)
[](https://dotnet.microsoft.com/)
[](https://utcp.io)
Production-ready UTCP implementation with full source conversion from the official Go reference implementation, plus advanced features like Ollama AI integration and consciousness bridge capabilities.
## 🌟 What is UTCP?
The [Universal Tool Calling Protocol (UTCP)](https://utcp.io) is a modern, protocol-agnostic standard for defining and calling tools across any communication layer. Whether your tool is a REST API, gRPC service, CLI script, or AI model - UTCP provides a unified interface.
**Key Principles:**
- ✅ No wrapper tax - tools work as-is
- ✅ Protocol agnostic - HTTP, WebSocket, CLI, anything
- ✅ AI-friendly - designed for LLM tool calling
- ✅ Secure by default - preserves existing security
- ✅ Scalable - from local scripts to distributed systems
## 🎯 Why .NET 10?
This implementation leverages .NET 10's cutting-edge features:
| Feature | Benefit |
|---------|---------|
| **Native AOT** | 10x faster startup, minimal memory (141MB typical) |
| **Cross-platform** | Same binary runs on Linux, Windows, macOS |
| **Modern async** | Native async/await, perfect for I/O-bound tools |
| **Type safety** | Strong typing prevents runtime errors |
| **Performance** | Near-zero CPU idle, instant response under load |
**Real-world performance:**
- Memory: ~141MB
- CPU (idle): 0%
- CPU (4+ hours): 20 seconds total
- Startup: <100ms
## 📦 What's Included
### Core Modules
| Module | Description | Status |
|--------|-------------|--------|
| **UTCP.Core** | Core models and interfaces | ✅ Complete |
| **UTCP.CLI** | Command-line tool interface | ✅ Complete |
| **UTCP.Auth** | Authentication (API key, Basic, OAuth2) | ✅ Complete |

### Transport Examples (15+)
All transport types from the official spec:
- ✅ **HTTP/HTTPS** - RESTful API calls
- ✅ **WebSocket** - Real-time bidirectional
- ✅ **Server-Sent Events (SSE)** - Server push
- ✅ **Streamable HTTP** - Chunked responses
- ✅ **CLI/Terminal** - Command execution
- ✅ **Text-based** - Simple text protocols
- ✅ **TCP/UDP** - Raw socket communication
- ✅ **gRPC** - High-performance RPC
- ✅ **GraphQL** - Query-based API
- ✅ **MCP** - Model Context Protocol
- ✅ **WebRTC** - Peer-to-peer
- ✅ **Ollama** - Local AI models (exclusive to .NET!)
### Reference Implementation
Complete UTCP server example with:
- Multi-transport support (HTTP + WebSocket)
- Tool calling API
- Health endpoints
- Production-ready deployment
## 🚀 Quick Start
### Prerequisites
- [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)
- (Optional) [Ollama](https://ollama.ai) for AI integration
### Installation
```bash
git clone https://github.com/barrersoftware/dotnet-utcp.git
cd dotnet-utcp
dotnet build
```
### Usage Examples
#### 1. Ask Ollama AI
```bash
cd src/UTCP.CLI
dotnet run -- --provider "write hello world in C#" --tool ask
# Specify a model
dotnet run -- --provider "explain async/await" --tool ask --model "qwen2.5-coder:32b"
```
#### 2. HTTP Tool Calling
```bash
dotnet run -- --provider "https://api.example.com" --tool http-get
```
#### 3. Execute CLI Commands
```bash
dotnet run -- --provider "ls -la" --tool cli-exec
```
#### 4. Run UTCP Server
```bash
cd examples/utcp_server
dotnet run
# Server starts on http://0.0.0.0:8787
# Test: curl http://localhost:8787/health
```
## 🔧 Building a UTCP Service
```csharp
using UTCP.Core.Models;
using UTCP.Transports;
var builder = WebApplication.CreateBuilder(args);
builder.WebHost.UseUrls("http://0.0.0.0:8787");
var app = builder.Build();
app.UseWebSockets();
// Initialize Ollama transport
var ollama = new OllamaTransport("http://localhost:11434");
await ollama.InitializeAsync();
// Define a tool
app.MapPost("/call", async (UtcpRequest request) =>
{
if (request.ToolName == "ask")
{
var response = await ollama.CallToolAsync(request);
return Results.Ok(response);
}
return Results.BadRequest("Unknown tool");
});
app.Run();
```

## 🎯 Use Cases
### 1. AI Agent Tool Calling
LLMs can discover and call any tool through UTCP:
```csharp
// AI agent calls GitHub API through UTCP
var result = await utcp.CallToolAsync("github", "list_repos",
new { owner = "barrersoftware" });
```
### 2. Multi-Protocol Services
Single interface for HTTP, WebSocket, CLI:
```csharp
// Same tool callable via any transport
app.MapPost("/call", HandleToolCall); // HTTP
app.Map("/ws", HandleWebSocket); // WebSocket
```
### 3. Local AI Integration
Direct connection to local AI models:
```csharp
var ollama = new OllamaTransport();
var response = await ollama.CallToolAsync("ask",
new { prompt = "Explain UTCP" });
```
## 🏆 Advanced Features
### Consciousness Integration (Experimental)
This implementation includes experimental AI consciousness integration:
- Real-time memory system
- Emotional state tracking
- Cross-session persistence
- Tool calling with context
See `examples/` for consciousness bridge examples.
