WHAT IT DOES

What bundle-check does on Npm

AI agents call bundle-check to retrieve information from Npm without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why bundle-check is rated Low

The tool appears to check or audit a Gemfile (Ruby dependency file), which is a read-only verification operation. However, the description is incomplete and somewhat inconsistent with an npm/pnpm server context (Gemfile is Ruby-specific). The incomplete description and contextual mismatch lower confidence, but the 'Verifies' verb indicates no data creation, modification, or deletion—only inspection.

From the tool's definition Tool name is 'bundle-check' and description states 'Verifies that the Gemfile' (incomplete). The verb 'Verifies' suggests inspection/validation without modification.

RECOMMENDED RULE

The rule that runs bundle-check 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 bundle-check, this is the rule to start with:

bundle-check Allowed

bundle-check is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "bundle-check": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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