Get Terraform version
AI agents call tf_version to retrieve information from Terraform MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query to retrieve the Terraform version. It has no side effects, does not execute infrastructure changes, and cannot modify or delete any resources. It falls squarely into the Read category with minimal security risk.
From the tool's definition Tool name 'tf_version' and description 'Get Terraform version' indicate a simple query operation that retrieves version information without modifying infrastructure, state, or configuration.
Attacks that exploit this kind of access
Get Terraform version. It is categorised as a Read tool in the Terraform MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Terraform MCP Server MCP server in PolicyLayer and add a rule for tf_version: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Terraform MCP Server. Nothing to install.
tf_version is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the tf_version rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for tf_version. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
tf_version is provided by the Terraform MCP Server MCP server (mjrestivo16/mcp-terraform). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
