DCP (Development Context Protocol) Integration

This module provides integration with the DCP crate for high-performance AI tool communication. DCP is our MCP competitor with 10-1000x performance improvements while maintaining backward compatibility.

§Features

  • Binary Message Envelope (BME) protocol support
  • Zero-Copy Tool Invocation (ZCTI)
  • MCP compatibility via McpAdapter
  • Capability manifest support
  • Ed25519 signing for secure tool definitions

§Usage

ⓘ
use driven::dcp::{DcpClient, DcpConfig};

let config = DcpConfig::default();
let mut client = DcpClient::new(config);

// Connect to a DCP server
client.connect("tcp://localhost:9000")?;

// Invoke a tool
let result = client.invoke_tool(tool_id, &args)?;

// Or use MCP fallback
let result = client.invoke_tool_mcp(&json_rpc_request)?;
