WHAT IT DOES

What update_pull_request does on GitHub

AI agents use update_pull_request 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 update_pull_request is rated Medium

This tool creates or modifies PR data without permanent deletion or code execution. It falls under Write category as changes are reversible. Severity is high because modifying PRs could mislead reviewers, alter project history representation, or manipulate CI/CD workflows if PR metadata triggers automated actions. The tool is on a code repository server, increasing potential impact on team workflows.

From the tool's definition Tool name is 'update_pull_request' with description 'Edit pull request'. The 'Edit' operation modifies PR metadata, description, title, labels, reviewers, or other attributes reversibly.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

update_pull_request Rate-limited

update_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.

          "counter": "update_pull_request_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 update_pull_request call is checked against it from then on.
