Why OpenTofu MCP is the candidate
OpenTofu MCP passed every step in Claude Code. It is the group’s site-wide candidate (judged 2026-10-20): Returned the latest hashicorp/aws provider version in both Claude Code and Cursor with no key, in 2 calls in total. HashiCorp's Terraform MCP and the archived Terraform Registry MCP also passed both with 2 calls each, so this is a tie on pass and calls; OpenTofu gets the nod for the smaller tool list (7 vs 9 and 10), the same tiebreak used in Browser automation. Terraform MCP also passed in ChatGPT (Codex). Servers that need a cloud account (Cloudflare, AWS, Kubernetes) aren't tested. Confirmed Oct 20, 2026: a second run in Claude Code and Cursor passed again (returned hashicorp/aws 6.69.1).
Provisional: based on one dated run per app (no repeat runs yet), so treat it as a candidate, not a final pick. How we test.
