WHAT IT DOES

What git_commit does on Git

AI agents use git_commit to create or update resources in Git, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Git environment.

RISK

Why git_commit is rated Medium

git_commit creates and modifies repository history by recording changes. This is a Write operation because it creates new data structures (commit objects) and modifies the repository state in a reversible way (commits can be amended or reverted). It is not Destructive because commits themselves cannot be undone without explicit revert/reset operations.

From the tool's definition Tool name is 'git_commit' and description states 'Record changes to the repository'. The git commit command creates a permanent record of staged changes in the repository's history.

RECOMMENDED RULE

The rule that runs git_commit 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 git_commit, this is the rule to start with:

git_commit Rate-limited

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.

View as policy code

policy.json

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

LIMIT THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about git_commit

What does the git_commit tool do? +

Record changes to the repository. It is categorised as a Write tool in the Git MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on git_commit? +

Register the Git MCP server in PolicyLayer and add a rule for 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 Git. Nothing to install.

What risk level is git_commit? +

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

Can I rate-limit git_commit? +

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

Set action: deny in the PolicyLayer policy for 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 git_commit? +

git_commit is provided by the Git MCP server (@modelcontextprotocol/server-git). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
