DevOps Dashboard MCP Server

Monitor and manage Linux infrastructure through your AI assistant. Built on the Model Context Protocol (MCP), this server gives Claude (or any MCP-compatible client) full visibility into your systems — services, logs, resources, containers, and more.

Tools

Tool	Description
`service_status`	Check systemd service status (active, failed, enabled state, PID, memory)
`service_logs`	Fetch journalctl logs with time range, priority, and grep filtering
`process_list`	List processes sorted by CPU/memory with optional name filtering
`disk_usage`	Disk space and inode usage by mount point
`memory_info`	RAM and swap usage, with optional /proc/meminfo details
`port_scan`	List listening TCP/UDP ports with associated processes
`cron_list`	List cron jobs for any/all users plus system cron files
`nginx_config`	Read, validate, and inspect nginx configuration and sites
`docker_status`	Container, image, volume, network, and resource usage overview
`system_health`	Aggregate health check with thresholds and warnings

Quick Start

Install from npm

npm install -g @devops-dashboard/mcp-server

Or run directly with npx

npx @devops-dashboard/mcp-server

Configure in Claude Code

Add to your Claude Code MCP settings (~/.claude/settings.json or project .mcp.json):

{
  "mcpServers": {
    "devops-dashboard": {
      "command": "npx",
      "args": ["@devops-dashboard/mcp-server"]
    }
  }
}

Configure in Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "devops-dashboard": {
      "command": "npx",
      "args": ["@devops-dashboard/mcp-server"]
    }
  }
}

Development

git clone https://github.com/turlockmike/devops-dashboard-mcp.git
cd devops-dashboard-mcp
npm install
npm run dev          # Start with tsx (hot reload)
npm run build        # Compile TypeScript
npm test             # Run test suite

Tool Details

service_status

Check whether a systemd service is running, its enabled/disabled state, PID, and recent status output.

Parameters:
  service (string, required) — Service name (e.g. "nginx", "sshd")
  user (boolean, optional) — Query user-level services (--user)

service_logs

Fetch recent journal logs with powerful filtering. Supports time ranges, priority levels, and text search.

Parameters:
  service (string, required) — Service name
  lines (number, 1-1000, default 50) — Number of log lines
  since (string, optional) — Time filter ("1h ago", "today", "2024-01-15")
  priority (string, optional) — Minimum level (emerg/alert/crit/err/warning/notice/info/debug)
  grep (string, optional) — Filter by pattern
  user (boolean, optional) — Query user-level service logs

process_list

List running processes with resource usage. Sort by CPU, memory, PID, or elapsed time.

Parameters:
  sort (string, default "cpu") — Sort field: cpu, mem, pid, time
  limit (number, 1-200, default 20) — Number of processes to show
  filter (string, optional) — Filter by process name (case-insensitive)

disk_usage

Show disk space and inode usage. Excludes virtual filesystems for clean output.

Parameters:
  path (string, optional) — Specific mount point or path
  human (boolean, default true) — Human-readable sizes

memory_info

RAM, swap, and system load. Detailed mode adds buffer/cache breakdown from /proc/meminfo.

Parameters:
  detailed (boolean, default false) — Include /proc/meminfo details

port_scan

List all listening network ports with their owning processes. Uses ss with netstat fallback.

Parameters:
  port (number, 1-65535, optional) — Check a specific port
  protocol (string, default "all") — Filter: tcp, udp, all

cron_list

Enumerate cron jobs across users and system directories.

Parameters:
  user (string, optional) — Specific user to query
  all (boolean, default false) — List jobs for ALL users
  include_system (boolean, default true) — Include /etc/crontab and /etc/cron.d/

nginx_config

Read and validate nginx configuration.

Parameters:
  action (string, required) — show, test, list_sites, or full_config
  site (string, optional) — Specific site config to read (with "show" action)

docker_status

Docker environment overview. Gracefully handles missing Docker or stopped daemon.

Parameters:
  action (string, default "overview") — overview, containers, images, stats, networks, volumes
  filter (string, optional) — Filter by container/image name

system_health

Aggregate health check that inspects memory, disk, load, failed services, and network listeners. Returns HEALTHY or ISSUES DETECTED with specific warnings.

Parameters:
  verbose (boolean, default false) — Include full details per subsystem

Requirements

Node.js >= 18
Linux (uses systemd, journalctl, ss, df, free, ps, etc.)
Optional: Docker, nginx (tools degrade gracefully if not present)

All system commands run through safeExec() which uses execFile (not exec) to prevent shell injection. Commands have configurable timeouts and output size limits.
