What init does on Cargo
AI agents invoke init to trigger actions in Cargo. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why init is rated High
The 'init' tool runs Terraform initialization which downloads external providers, configures backends, and sets up the working directory. These are external operations with side effects (network downloads, file system changes, backend configuration) that depend on arguments. While not directly destructive, it triggers external operations and prepares infrastructure tooling, placing it in the Execute category.
From the tool's definition Initializes a Terraform working directory. Downloads providers, configures backend, and prepares for plan/apply.
Attacks that exploit this kind of access
The rule that runs init safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Cargo, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For init, this is the rule to start with:
init stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Cargo, apply this rule, and every init call is checked against it from then on.
Questions about init
Initializes a Terraform working directory. Downloads providers, configures backend, and prepares for plan/apply. It is categorised as a Execute tool in the Cargo MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Cargo MCP server in PolicyLayer and add a rule for init: 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 Cargo. Nothing to install.
init is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the init 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 init. 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.
init is provided by the Cargo MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
