AMQP Transport Integration (Enterprise Message Bus Mode)

The AMQP transport enables horizontally scalable, decoupled MCP request/response flows over RabbitMQ. This allows infrastructure discovery, monitoring enrichment, and AI agent orchestration to share a common secure event fabric.

Architecture Highlights

  • Topic-based exchanges for routing (mcp.notifications, per‑session routing exchange)
  • Per-session ephemeral queues with TTL & auto-delete for isolation
  • Structured routing keys: mcp.request.<category>.<method> and notification fan-out (mcp.notification.#)
  • Heartbeat exchange (mcp.heartbeat) for liveness & operational dashboards
  • Idempotent lifecycle: SDK triggers start(); initialize response flows through AMQP channel
  • Capability negotiation preserved across transports

Enterprise Use Cases

Use CaseBenefit
Cross-Datacenter DiscoveryRoute tool calls via AMQP without direct network exposure

MCP Open Discovery v2.0 🚀🔥

Enterprise-grade Model Context Protocol (MCP) server for infrastructure discovery, lightweight CMDB, and tooling orchestration. Designed for security-conscious environments, built on the official MCP SDK, and deployable with containers by default.


This project was substantially coded with AI under human direction and review. Code and architecture decisions were guided, verified, and integrated by humans.

Overview

MCP Open Discovery provides a single MCP server that exposes a broad set of discovery, monitoring, and CMDB-style capabilities via tools. It uses a centralized tool registry with hot‑reload, an SQLite-backed persistent store for CIs, and a container-first deployment approach.

This README aims to describe current capabilities plainly and avoid over‑claiming. For regulated or large enterprise environments, please evaluate features in a staging environment before production use.

Highlights

  • Single MCP server instance shared by multiple transports
  • Central tool registry with hot‑reload and modular categories
  • SQLite-backed persistent memory/CMDB with manual and periodic saves
  • Credential management with encryption and audit logging
  • Structured logging and a health endpoint for basic observability

Current Transport Support

  • HTTP: supported and enabled by default (port 3000). Recommended convention for remote clients: port 6270 (set HTTP_PORT=6270).
  • Stdio: supported for local/embedded scenarios
  • AMQP (RabbitMQ): available; evaluated in practice. Suitable for non-interactive integrations. For IDE integrations, confirm MCP transport compliance in your environment.
  • gRPC: not enabled; future consideration

Notes:

  • Transport selection can be tailored per deployment. Validate AMQP behavior with your client stack before relying on it.

Tooling Scope (overview)

The server typically registers 70+ tools across these categories (exact counts can vary by build):

  • Memory (CMDB/persistence)
  • Credentials
  • Network (ping, DNS, HTTP fetch, routes, interfaces, ARP, etc.)
  • Nmap scanning (capability-aware)
  • SNMP discovery and inspection
  • Proxmox cluster inspection
  • Zabbix integration (inventory, metrics, events)
  • Registry/Hot‑reload management
  • Test/Debug utilities

Refer to the code under tools/ for the authoritative list and schemas.

Architecture basics

  • Server: mcp_open_discovery_server.js creates a single MCP server instance and starts available transports.
  • Registry: tools/registry/index.js centralizes tool loading/registration and hot‑reload management.
  • Persistence: tools/memory_tools_sdk.js uses SQLite (via tools/registry/database_layer.js) to persist CI data.
  • Credentials: encrypted storage with audit trails (see tools/credentials_tools_sdk.js).

Architecture diagram

  • Full diagram (Mermaid):
  • Tip: In VS Code, install a Mermaid preview extension to view it; you can also copy the content into a Markdown ```mermaid block for GitHub rendering.

Design considerations:

  • Prefer least privilege (Docker capabilities vs. privileged mode for scans).
  • Avoid duplicate registrations via a single server instance.
  • Provide stable defaults with clear extension points.

Quick start

Prerequisites: Docker Desktop (includes Docker Compose), Git

Windows (PowerShell):

./rebuild_deploy.ps1

Linux/Mac (alternative):

docker compose -f docker/docker-compose.yml up -d

Verify:

curl http://localhost:6270/health

Runtime paths

  • Data: /home/mcpuser/app/data (container volume)
  • Logs: /home/mcpuser/app/logs (container volume)
  • Plugins: default /home/mcpuser/plugins in containers (mounted volume). When running locally, defaults to <home>/plugins then <cwd>/plugins if needed. Override with PLUGINS_ROOT (must be writable).

Minimal production compose

For a lean, production-only deployment of the MCP server:

  • HTTP only: docker compose -f docker/docker-file-mcpod-server.yml up -d
  • With AMQP broker (RabbitMQ): docker compose -f docker/docker-file-mcpod-server.yml --profile with-amqp up -d The prod scripts below auto-set TRANSPORT_MODE; if running manually, set TRANSPORT_MODE=http,amqp.

Deployment scripts

  • Windows (full stack or server-only):
    • Full/dev stack: ./rebuild_deploy.ps1 (uses docker/docker-compose.yml)
    • Minimal production server: ./rebuild_deploy_prod.ps1
      • Transports (choose any): -Http, -Amqp, -Stdio (default -Http if none specified)
      • RabbitMQ container: -WithRabbitMq (optional; use with -Amqp if you want an in-stack broker)
      • Note: the prod script will include HTTP alongside AMQP when -WithRabbitMq is used so the container's HTTP healthcheck stays green. If invoking Compose manually with the RabbitMQ profile, set TRANSPORT_MODE=http,amqp.
      • Project scoping: -ProjectName <name> (overrides COMPOSE_PROJECT_NAME; auto-lowercased for Docker)
      • Deprecated: -WithAmqp (alias of -Amqp -WithRabbitMq)
  • Linux/macOS:
    • Full/dev stack: ./rebuild_redeploy.sh (uses docker/docker-compose.yml)
    • Minimal production server: ./rebuild_redeploy_prod.sh
      • Transports: --http, --amqp, --stdio (default --http if none specified)
      • RabbitMQ container: --with-rabbitmq (optional)
      • Project scoping: --project-name <name> or COMPOSE_PROJECT_NAME (will be normalized to lowercase)
      • Deprecated: --with-amqp (alias of --amqp --with-rabbitmq)

Security notes

  • Credentials are stored encrypted with audit logging; integrate with your secrets management process for production.
  • CI persistence uses SQLite; apply host or volume encryption per policy if required.
  • Network scanning tools (e.g., nmap) may require extra container capabilities; review docker/docker-compose.yml before enabling.

Operational notes

  • Hot‑reload is supported for tool modules; validate in lower environments before promoting changes.
  • Tool counts and schemas may evolve; use the MCP tools/list method to discover the current interface.
  • AMQP usage depends on client compatibility with MCP transports. Test end‑to‑end in your stack if you plan to rely on AMQP.

🛡️ Security & Compliance

🔐 Enterprise-Grade Security

  • Encrypted Credential Storage - AES-256 encryption for all stored credentials
  • Audit Trails - Complete logging of all credential access and modifications
  • Input Sanitization - Advanced validation for all tool parameters
  • Rate Limiting - DDoS protection and resource management
  • Non-Root Execution - Container security best practices with capability-based privilege escalation
  • Linux Capabilities - Minimal privilege model for network operations (NET_RAW, NET_ADMIN, NET_BIND_SERVICE)

⚡ Capability-Based Security Model

Our innovative security approach provides enterprise-grade functionality while maintaining strict security boundaries:

# Dockerfile - Minimal privilege escalation
RUN setcap cap_net_raw,cap_net_admin,cap_net_bind_service+eip /usr/bin/nmap
USER mcpuser  # Non-root execution
# docker-compose.yml - Container capabilities
services:
  mcp-server:
    cap_add:
      - NET_RAW # Raw socket access for SYN/UDP scans
      - NET_ADMIN # Network admin for advanced operations
      - NET_BIND_SERVICE # Bind to privileged ports

Security Benefits:

  • Principle of Least Privilege: Only necessary capabilities granted
  • Attack Surface Minimization: No full root access required
  • Container Security: Docker security model maintained
  • Audit Compliance: All privileged operations logged and traceable

📋 Compliance Features

  • ITIL v4 Standards - Built-in CMDB classification and CI management
  • SOX/PCI/HIPAA Ready - Compliance gap analysis prompts
  • Change Management - Structured incident response frameworks
  • Access Controls - Role-based credential management
