WHAT IT DOES

What package-init does on Npm

AI agents invoke package-init to trigger actions in Npm. 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 package-init is rated High

Initializing a new Swift package executes a scaffolding operation that creates files and directory structures on the filesystem. This is more than a simple Write because it triggers an external tool execution (swift package init) that sets up a project environment. The blast radius is medium — it creates new files but doesn't overwrite or delete existing data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs package-init safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Npm, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For package-init, this is the rule to start with:

package-init Rate-limited

package-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.

      "limits": [
        {

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

      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Npm, apply this rule, and every package-init call is checked against it from then on.

FAQ

Questions about package-init

What does the package-init tool do? +

Initializes a new Swift package and returns structured result with created files. It is categorised as a Execute tool in the Npm MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on package-init? +

Register the Npm MCP server in PolicyLayer and add a rule for package-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 Npm. Nothing to install.

What risk level is package-init? +

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

Can I rate-limit package-init? +

Yes. Add a rate_limit block to the package-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.

How do I block package-init completely? +

Set action: deny in the PolicyLayer policy for package-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.

What MCP server provides package-init? +

package-init is provided by the Npm MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
