Why create_pull_request needs a policy

This tool creates a new pull request, which is a write operation that modifies repository state by introducing a proposed change. While pull requests are reversible (they can be closed or abandoned without merging), they do represent a tangible creation of collaborative artifacts.

From the tool's definition Tool name 'create_pull_request' and description 'Create a new pull request in a repository' indicate creation of a reversible modification to repository state. Pull requests are standard collaborative objects that can be closed, abandoned, or reverted.

POLICY

How to control create_pull_request

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

policy.json

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

create_pull_request 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 AtomGit MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
