Frequently asked questions
Which MCP server is faster to set up, Datadog MCP or PagerDuty MCP?

What authentication does each server need?
Datadog MCP authenticates with API + app keys. PagerDuty MCP uses PagerDuty API key. Store secrets in a password manager or your shell's keychain and inject them via environment variables; never commit them to the MCP config file, which is often synced across machines.
Which one should I pick first if I am just starting with MCP?
Start with whichever backend you already pay for or use daily. If you do not use either yet, both require a paid account; pick based on the service you plan to use most. You can always add the second one later without disrupting the first.
