MCP Servers

MCP Server Health Monitor

Enables LLMs to monitor server health through natural language, including HTTP endpoint checks, disk/memory/CPU usage, port status, and process listings.

README

MCP Server Health Monitor

An MCP (Model Context Protocol) server that lets LLMs monitor server infrastructure. Connect it to OpenCode, Claude Code, or any MCP-compatible client and ask natural language questions about your server's health.

What it does

Ask your LLM things like:

"Is my web server responding?"
"How much disk space do I have left?"
"What processes are using the most memory?"
"Is port 3306 open?"

Tools

Tool	Description
`check_http_endpoint`	Check if a URL responds with 200 OK
`check_disk_usage`	Get disk space info
`check_memory_usage`	Get RAM and swap usage
`check_cpu_usage`	Get CPU utilization per core
`check_port`	Check if a TCP port is open
`list_processes`	List running processes with optional filtering

Resources

Resource	Description
`system://info`	OS, hostname, uptime
`system://health`	Aggregated health status

Tech stack

Python 3.12+
MCP Python SDK v2
psutil (system metrics)
httpx (HTTP checks)

Setup

Install dependencies:

uv sync

Run the server:

uv run mcp-server-monitor

Or run directly:

uv run python -m mcp_server_monitor

Testing with MCP Inspector

uv run mcp dev src/mcp_server_monitor/server.py

This opens the MCP Inspector in your browser where you can call tools interactively.

Connecting to OpenCode

Add to your opencode.json:

{
  "mcpServers": {
    "server-monitor": {
      "command": "uv",
      "args": ["run", "--project", "C:\\Users\\nikol\\Documents\\mcp-server-monitor", "mcp-server-monitor"]
    }
  }
}

Running tests

uv run pytest
