THE RISK

Medium Risk

Why create_issue needs a policy

Creating an issue is a write operation that adds new content to a repository but does not irreversibly delete data or execute arbitrary code. While it could be misused to spam issues or create misleading reports, the blast radius is contained to issue creation and the action is reversible, warranting a medium severity classification.

From the tool's definition The tool is described as 'Create a new GitHub Issue in a repository', which creates new data (an issue) in a reversible manner. This is a write operation that can be undone by deleting the issue.

POLICY

How to control create_issue

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

policy.json

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

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

FAQ

Questions about create_issue

What does the create_issue tool do? +

Create a new GitHub Issue in a repository. It is categorised as a Write tool in the Gitbridge MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_issue? +

Register the Gitbridge MCP server in PolicyLayer and add a rule for create_issue: 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 Gitbridge. Nothing to install.

What risk level is create_issue? +

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

Can I rate-limit create_issue? +

Yes. Add a rate_limit block to the create_issue 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 create_issue completely? +

Set action: deny in the PolicyLayer policy for create_issue. 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 create_issue? +

create_issue is provided by the Gitbridge MCP server (iotus/gitbridge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Gitbridge tool call.

Start from Gitbridge, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
