WHAT IT DOES

What commit does on Github

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

RISK

Why commit is rated Medium

This tool writes/creates commits in a Git repository, modifying the commit history and potentially affecting branches. While commits can be undone via revert or reset, they represent a persistent change to the repository state and affect collaboration workflows.

From the tool's definition Tool description states it 'Creates a commit with the given message' and returns commit metadata. The term 'Creates' indicates data modification via version control, which is reversible through git operations (revert, reset).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs commit safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Github, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For commit, this is the rule to start with:

commit Rate-limited

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": {
    "commit": {
      "limits": [
        {
          "counter": "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 Github, apply this rule, and every commit call is checked against it from then on.

FAQ

Questions about commit

What does the commit tool do? +

Creates a commit with the given message. Returns structured data with hash, message, and change statistics. Pass. It is categorised as a Write tool in the Github MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on commit? +

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

What risk level is commit? +

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

Can I rate-limit commit? +

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

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

commit is provided by the Github MCP server (@paretools/github). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
