WHAT IT DOES

What pr-create does on Build

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

RISK

Why pr-create is rated Medium

This tool creates new pull requests, which modifies the state of a repository by introducing a new code review artifact. While reversible (PRs can be closed), it represents a write operation that changes repository state and may trigger CI/CD pipelines or notifications.

From the tool's definition Tool name 'pr-create' and description 'Creates a new pull request' indicate creation of new data/resources in a version control system.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pr-create safely

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

pr-create Rate-limited

pr-create 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.

          "window": "minute",
          "max": 30,

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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