Terraform MCP Server
Looks up Terraform Registry documentation and can manage HCP Terraform or Terraform Enterprise workspaces and runs.
“Terraform MCP Server”
01 / THE REASONING
Why this made the selection.
- Combines provider/module documentation with separately credentialed workspace operations.
- Offers tool/toolset filters and an organization allowlist for scoped deployments.
02 / THE REVIEW RECORD
What we actually inspected.
Source review has boundaries.
A clear record is more useful than a “safe” badge.
Material inspected
- README.md (installation, capability and permission sections)
- go.mod
- cmd/terraform-mcp-server/main.go
- LICENSE
Our findings
- The implementation defaults to stdio and supports Streamable HTTP bound to loopback by default.
- MPL-2.0 covers this server; it is not a statement about every Terraform product’s licence.
Not established by this review
- Server startup, authentication and tool execution were not tested.
The review applies to the material and revision named here. A newer upstream release can change its behavior.
03 / PUT IT TO WORK
Connect a server deliberately.
DOCUMENTED COMMAND
docker run -i --rm hashicorp/terraform-mcp-serverCopying does not execute this command. It may retrieve a newer version than the reviewed source.
- Use the container as the MCP client’s stdio command.
- For HCP/TFE operations, configure TFE_ADDRESS/TFE_TOKEN and restrict toolsets and organizations.
Before you start
- Docker; HCP Terraform or Terraform Enterprise access only for account operations.
04 / FOLLOW THE EVIDENCE
The source trail.
Our notes are separate from the original resource.
