Verdict

Pick PagerDuty MCP if you want the official, vendor-maintained server, and you need the broadest set of tools.

Pick Prometheus MCP Server if you prefer the more popular, battle-tested option, and you want zero-setup with no API key.

Add PagerDuty MCP

{
  "mcpServers": {
    "pagerduty-mcp": {

      "args": [
        "pagerduty-mcp"
      ],
      "env": {
        "PAGERDUTY_USER_API_KEY": "<your-pagerduty-user-api-token>"
