About

The Terraform MCP server (hashicorp/terraform-mcp-server, MPL-2.0, ~1.5k stars) gives agents Terraform superpowers: search the registry, look up provider documentation, and validate configurations.

Official HashiCorp, actively maintained. The end of agents hallucinating provider arguments — they can read the actual docs.

  • Config validation helpers

  • MPL-2.0 open source

Setup

  1. Add the server to your MCP config (npx or Docker per README).
