WHAT IT DOES

What pr-reopen does on Git

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

RISK

Why pr-reopen is rated Medium

Reopening a pull request is a reversible state change on an existing resource — it modifies the PR's state from closed to open and can optionally add a comment. This fits the Write category (creates or modifies data reversibly). It does not execute code, delete data, or move money.

From the tool's definition Reopens a previously closed pull request, optionally with a comment. Returns structured data with PR number, state, and URL.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pr-reopen safely

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

pr-reopen Rate-limited

pr-reopen 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.

          "max": 30,

        }
      ]
    }

}

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

FAQ

Questions about pr-reopen

What does the pr-reopen tool do? +

Reopens a previously closed pull request, optionally with a comment. Returns structured data with PR number, state, and URL. It is categorised as a Write tool in the Git MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on pr-reopen? +

Register the Git MCP server in PolicyLayer and add a rule for pr-reopen: 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 Git. Nothing to install.

What risk level is pr-reopen? +

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

Can I rate-limit pr-reopen? +

Yes. Add a rate_limit block to the pr-reopen 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 pr-reopen completely? +

Set action: deny in the PolicyLayer policy for pr-reopen. 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 pr-reopen? +

pr-reopen is provided by the Git MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
