Why fleet_git_commit needs a policy

This tool stages and commits file changes to Git—a classic Write operation that modifies repository history. While commits are technically reversible (via git revert/reset), they do represent persistent state changes to version control. In the context of a production management server for Docker Compose applications, a malicious agent could commit unauthorized code, configuration changes, or secrets.

From the tool's definition Tool name 'fleet_git_commit' and description 'Stage tracked file changes and commit' indicate this creates a new Git commit (a reversible write operation) in the repository.

POLICY

How to control fleet_git_commit

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "fleet_git_commit": {
      "limits": [
        {
          "counter": "fleet_git_commit_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

fleet_git_commit stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Fleet — 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 fleet_git_commit

What does the fleet_git_commit tool do? +

Stage tracked file changes and commit. It is categorised as a Write tool in the Fleet MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on fleet_git_commit? +

Register the Fleet MCP server in PolicyLayer and add a rule for fleet_git_commit: 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 Fleet. Nothing to install.

What risk level is fleet_git_commit? +

fleet_git_commit is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit fleet_git_commit? +

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

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

fleet_git_commit is provided by the Fleet MCP server (wrxck/fleet). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Fleet tool call.

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