Shows the Terraform execution plan with resource change counts. Read-only — does not modify infrastructure.

What plan does on Test
AI agents call plan to retrieve information from Test without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why plan is rated Low
The tool runs 'terraform plan' which only computes and displays what changes would be made, explicitly stated as read-only with no infrastructure modifications. Blast radius is low as no state is changed.
From the tool's definition Read-only — does not modify infrastructure
Attacks that exploit this kind of access
The rule that runs plan safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Test, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For plan, this is the rule to start with:
plan is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Test, apply this rule, and every plan call is checked against it from then on.
Questions about plan
Shows the Terraform execution plan with resource change counts. Read-only — does not modify infrastructure. It is categorised as a Read tool in the Test MCP Server, which means it retrieves data without modifying state.
Register the Test MCP server in PolicyLayer and add a rule for plan: 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 Test. Nothing to install.
plan 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 plan 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 plan. 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.
plan is provided by the Test MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
