THE RISK

Medium Risk

Why nina_reset_image_parameters needs a policy

Resetting parameters modifies configuration state (a reversible write operation) by overwriting current settings with defaults. It does not delete data, execute code, or have financial impact, but misuse could disrupt ongoing imaging sessions by unexpectedly changing all image capture parameters.

POLICY

How to control nina_reset_image_parameters

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

policy.json

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

nina_reset_image_parameters 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.

FAQ

Questions about nina_reset_image_parameters

What does the nina_reset_image_parameters tool do? +

Reset all image parameters to their default values in NINA astronomy software. It is categorised as a Write tool in the Nina Advanced API MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on nina_reset_image_parameters? +

Register the Nina Advanced API MCP server in PolicyLayer and add a rule for nina_reset_image_parameters: 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 Nina Advanced API MCP. Nothing to install.

What risk level is nina_reset_image_parameters? +

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

Can I rate-limit nina_reset_image_parameters? +

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

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

nina_reset_image_parameters is provided by the Nina Advanced API MCP server (padev1/nina_advanced_api_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Nina Advanced API MCP tool call.

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