Why create_issue needs a policy

Creating an issue is a write operation that generates new content (issue title, description, metadata) in a GitHub repository. While reversible (issues can be deleted), it modifies repository state and increases organizational complexity.

From the tool's definition Tool description explicitly states 'Create a new issue in a GitHub repository' - a create operation that adds new data to a repository.

Documented attack patterns abuse exactly the kind of access create_issue gives an agent:

POLICY

How to control create_issue

PolicyLayer is an MCP gateway — it sits between your AI agents and GitHub MCP Server Plus, 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 GitHub MCP Server Plus — 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 issue in a GitHub repository. It is categorised as a Write tool in the GitHub MCP Server Plus 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 GitHub MCP Server Plus 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 GitHub MCP Server Plus. 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 GitHub MCP Server Plus MCP server (phialsbasement/mcp-github-server-plus). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every GitHub MCP Server Plus tool call.

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