FAQ
AWS vs Terraform: which MCP server should I use?
Pick AWS when incident investigation. Pick Terraform when grounding generated hcl in real provider schemas. AWS is built for inspect aws, while Terraform focuses on query terraform registry.
Can I run both AWS and Terraform together?
Yes. MCP clients run each server as a separate process and surface every server's tools simultaneously, so you can install both and let your agent decide which to call. Be deliberate with auth scopes when stacking servers.
