WHAT IT DOES

What git_merge does on GitHub MCP Server

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

RISK

Why git_merge is rated Medium

git_merge integrates changes from one branch into another, modifying the repository state. While it's reversible (can be reset/reverted), it can introduce widespread changes across many files and may cause conflicts.

RECOMMENDED RULE

The rule that runs git_merge safely

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

git_merge Rate-limited

git_merge 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.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "git_merge": {
      "limits": [
        {
          "counter": "git_merge_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 MCP Server, apply this rule, and every git_merge call is checked against it from then on.

What risk level is git_merge? +

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

Can I rate-limit git_merge? +

Yes. Add a rate_limit block to the git_merge 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_merge completely? +
