Why remove_assignees_from_issue needs a policy

Removing assignees from an issue is a reversible modification to issue metadata (assignees can be re-added). This is a Write operation. It does not delete data permanently, execute code, or involve finances. Severity is medium as misuse could disrupt issue tracking and assignment workflows.

From the tool's definition 'Remove assignees from an issue' — modifies issue metadata by removing assignees

POLICY

How to control remove_assignees_from_issue

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

policy.json

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

remove_assignees_from_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.
