WHAT IT DOES

What restore does on Cargo

AI agents invoke restore 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 restore is rated High

The tool executes a dotnet CLI command that fetches and installs NuGet packages from external registries. While restore is generally considered safe, it runs external code/binaries and modifies the local environment by downloading packages, making it Execute category. The blast radius is medium since it could potentially pull malicious packages or modify project dependencies.

From the tool's definition 'Runs dotnet restore to restore NuGet dependencies' — triggers an external CLI operation (dotnet restore) that downloads and installs packages from external sources

RECOMMENDED RULE

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

restore Rate-limited

restore 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.

          "window": "minute",
          "max": 10,

FAQ

Questions about restore

What does the restore tool do? +

Runs dotnet restore to restore NuGet dependencies and returns structured results. 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 restore? +

Register the Cargo MCP server in PolicyLayer and add a rule for restore: 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 restore? +

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

Can I rate-limit restore? +

Yes. Add a rate_limit block to the restore 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 restore completely? +

Set action: deny in the PolicyLayer policy for restore. 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 restore? +

restore 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.
