THE RISK

Why reset needs a policy

The 'reset' tool with hard mode capability is destructive because it can irreversibly discard or overwrite data (uncommitted changes, staged changes, or commits depending on mode). While soft/mixed modes are reversible, the inclusion of 'hard' and 'keep' modes means this tool can cause permanent data loss. The blast radius is high as an AI agent misusing hard reset could lose significant work.

From the tool's definition Tool name is 'reset' with description stating it 'Resets the current HEAD to a specified state' with support for 'hard' mode, which irreversibly discards uncommitted changes and moves HEAD. This is a git reset operation that can permanently lose work.

POLICY

How to control reset

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "reset"
  ]
}

reset disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Npm — 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 reset

What does the reset tool do? +

Resets the current HEAD to a specified state. Supports soft, mixed, hard, merge, and keep modes. The. It is categorised as a Destructive tool in the Npm MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on reset? +

Register the Npm MCP server in PolicyLayer and add a rule for reset: 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 reset? +

reset is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit reset? +

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

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

reset 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.

Enforce policy on every Npm tool call.

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