WHAT IT DOES

What get does on Cargo

AI agents invoke get 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.

RISK

Why get is rated High

This tool performs network operations (downloads) and modifies the system by installing packages and dependencies. It triggers external operations with side effects beyond simple data retrieval, making it Execute. Misuse could install malicious packages or alter the environment, warranting medium severity.

RECOMMENDED RULE

The rule that runs get 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 get, this is the rule to start with:

get Rate-limited

get 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.

FAQ

Questions about get

What does the get tool do? +

Downloads and installs Go packages and their dependencies. 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.

How do I enforce a policy on get? +

Register the Cargo MCP server in PolicyLayer and add a rule for get: 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.

What risk level is get? +

get is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit get? +

Yes. Add a rate_limit block to the get 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.

How do I block get completely? +

Set action: deny in the PolicyLayer policy for get. 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.

What MCP server provides get? +

get 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.
