THE RISK

Low Risk

Why bundle-check needs a policy

The tool performs a checking/verification operation on a Gemfile (Ruby dependency file), which is a read-only diagnostic action. It queries or validates data without creating, modifying, executing arbitrary operations, or deleting anything. Verification and check operations are classified as Read category with low severity since they have no side effects or system impact beyond retrieving status information.

From the tool's definition Tool name 'bundle-check' and description 'Verifies that the Gemfile' indicate a verification/check operation that reads and validates configuration without modifying state. Verification operations are non-destructive reads.

POLICY

How to control bundle-check

PolicyLayer is an MCP gateway — it sits between your AI agents and Make, and nothing reaches the server without passing your rules. This is the rule we recommend for bundle-check:

policy.json

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

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

Create a free account and register Make — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about bundle-check

What does the bundle-check tool do? +

Verifies that the Gemfile. It is categorised as a Read tool in the Make MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on bundle-check? +

Register the Make MCP server in PolicyLayer and add a rule for bundle-check: 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 Make. Nothing to install.

What risk level is bundle-check? +

bundle-check is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit bundle-check? +

Yes. Add a rate_limit block to the bundle-check 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 bundle-check completely? +

Set action: deny in the PolicyLayer policy for bundle-check. 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 bundle-check? +

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

Enforce policy on every Make tool call.

Start from Make, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
