What reset does on Git
AI agents call reset to permanently remove resources in Git, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why reset is rated Critical
Git reset, particularly in hard mode, irreversibly modifies the working directory and staging area by discarding changes. While soft/mixed modes are reversible, the tool's explicit support for hard reset (which overwrites local work) and the potential to reset to arbitrary states makes it destructive. An AI agent could lose user data or commits.
From the tool's definition Tool name '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. Hard reset cannot be undone without access to reflog.
Attacks that exploit this kind of access
The rule that runs reset safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Git, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For reset, this is the rule to start with:
reset is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Git, apply this rule, and every reset call is checked against it from then on.
Questions about reset
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 Git MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Git 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 Git. Nothing to install.
reset is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
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.
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.
reset is provided by the Git MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
