What's Good

MPL-2.0 (hashicorp/terraform-mcp-server), release v1.3.0 (2026-08-26), commit on 2026-10-19. ★~1.6k (~19 a week). Useful when your agent writes Terraform and keeps guessing provider arguments; it can look up the current docs instead.

The Catch

MPL-2.0 is weak copyleft: changes you make to its files have to stay open. Registry docs work without an account, but workspace actions need an HCP Terraform token.

Verdict

The official way to give an agent current Terraform docs.
