Why ollama_refactor_code needs a policy

Refactoring creates or modifies code reversibly without executing it or deleting data permanently. The changes can be reviewed, undone, or rejected. While it affects code, it does not run code (Execute), delete it (Destructive), or incur financial obligations (Financial).

From the tool's definition Tool description states 'Refactor code to improve quality, readability, or structure' — refactoring modifies code structure and content.

POLICY

How to control ollama_refactor_code

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

policy.json

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

ollama_refactor_code 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
