JarvisDiscovery.McpServer 1.1.0

HP Jarvis Discovery MCP Server

A Model Context Protocol (MCP) server that exposes Jarvis Discovery APIs for AI agents to discover and manage HP printers.

Features

Based on: Jarvis\xamarin-discovery\harness\HP.Jarvis.Discovery.Harness\ViewModel\MainViewModel.cs

Available Tools

1. discovery.start_search - Start printer discovery with all providers
2. discovery.stop_search - Stop active search
3. discovery.search_by_address - Find printer by IP/hostname
4. discovery.search_by_uuid - Find printer by UUID
5. discovery.refresh_device - Refresh device information
6. discovery.verify_connection - Verify network connectivity
7. discovery.get_devices - Get all discovered devices
8. discovery.check_internet - Check internet connectivity
9. discovery.set_providers - Enable/disable discovery providers (USB, mDNS, WSD, BLE, WiFi AP)

Build & Run

cd c:\Users\NaAm727\Downloads\AgentRegistryUI\AiNativeApp\HP.Jarvis.Discovery.McpServer

Architecture

• DryIoc - Dependency injection matching PrinterControl4 pattern
• Real Jarvis Services - IDeviceDiscoveryService, IConnectionHelper, IHPSystemUtilities
• Event-based Discovery - Subscribes to DiscoveryEvent for real-time device detection
• 9 MCP Tools - Complete printer discovery API surface

Integration

This server can be called by any AI agent or LLM that supports the MCP protocol. Each tool returns structured JSON results that agents can parse and act upon.
