THE RISK

Low Risk

Why list_screenshots needs a policy

This tool retrieves and enumerates screenshot artifacts from a simulator without modifying, deleting, or executing any code. It is a passive information-gathering operation. Severity is low because screenshots of a game development project pose minimal security risk even if disclosed; the blast radius of misuse is limited to information exposure of visual assets.

From the tool's definition Tool name 'list_screenshots' and description 'List all available screenshots from the Solar2D simulator' indicate a retrieval operation with no side effects. The verb 'list' is explicitly a read-only action that queries existing data.

POLICY

How to control list_screenshots

PolicyLayer is an MCP gateway — it sits between your AI agents and Solar2D MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_screenshots:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_screenshots": {}
  }
}

list_screenshots is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Solar2D MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on list_screenshots? +

Register the Solar2D MCP Server MCP server in PolicyLayer and add a rule for list_screenshots: 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 Solar2D MCP Server. Nothing to install.

What risk level is list_screenshots? +

Can I rate-limit list_screenshots? +

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

What MCP server provides list_screenshots? +

list_screenshots is provided by the Solar2D MCP Server MCP server (sensiblecoder/solar2d-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Solar2D MCP Server tool call.

Start from Solar2D MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
