infra-diagnostics-mcp

An MCP server exposing infrastructure diagnostic tools (port checks, DNS lookups, log parsing, system health, SSL cert inspection) over stdio.

Setup

cd /Users/kuuashwa/Desktop/Workspace/MyProjects/infra-diagnostics-mcp
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Run Standalone (for testing)

python server.py

The server reads JSON-RPC from stdin and writes to stdout. Not useful to run manually — it's meant to be launched by an MCP client.

Add to opencode

Edit ~/.config/opencode/config.json:

{
  "mcpServers": {
    "infra-diagnostics": {
      "type": "stdio",

      "args": ["server.py"],
      "cwd": "/Users/kuuashwa/Desktop/Workspace/MyProjects/infra-diagnostics-mcp"
    }
  }
}
