What turbo does on Cargo
AI agents invoke turbo 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 turbo is rated High
The tool runs Turborepo tasks, which involves executing arbitrary build scripts, test runners, and other configured tasks across multiple packages in a monorepo. This is a task execution tool that can trigger a wide range of operations depending on what tasks are configured. The blast radius is high because it can execute code across many packages simultaneously.
From the tool's definition 'Runs Turborepo tasks' — actively executes build/task pipeline operations across packages
Attacks that exploit this kind of access
The rule that runs turbo 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 turbo, this is the rule to start with:
turbo 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 turbo call is checked against it from then on.
Questions about turbo
Runs Turborepo tasks and returns structured per-package results with cache hit/miss info. 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 turbo: 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.
turbo 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 turbo 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 turbo. 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.
turbo 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.
