Crate plexus_core 

Hub Core - Core infrastructure for building Plexus RPC servers

This crate provides:

• DynamicHub - Dynamic routing hub for activations (implements Plexus RPC protocol)
• Activation - Trait for implementing activations
• PlexusMcpBridge - MCP server integration
• Handle - Typed references to activation method results

Example

use plexus_core::plexus::DynamicHub;
use plexus_core::activations::echo::Echo;
use plexus_core::activations::health::Health;
use std::sync::Arc;

let hub = Arc::new(
    DynamicHub::new("myapp")
        .register(Health::new())
        .register(Echo::new())
);
