Why list_textures needs a policy

This tool retrieves or lists texture data from RenderDoc GPU frame captures with no apparent side effects. It is a query operation consistent with the server's debugging and analysis mission. The blast radius of misuse is minimal—an AI could only view texture metadata, not modify graphics state, execute code, or cause irreversible changes.

From the tool's definition Tool name 'list_textures' indicates a query/retrieval operation. The sibling tools on this server (analyze_bandwidth, analyze_render_passes, debug_shader_at_pixel, etc.) are all read-only analysis operations that inspect GPU frame capture data without…

POLICY

How to control list_textures

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

policy.json

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

list_textures 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 Renderdoc — 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 list_textures

What does the list_textures tool do? +

list_textures. It is categorised as a Read tool in the Renderdoc MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_textures? +

Register the Renderdoc MCP server in PolicyLayer and add a rule for list_textures: 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 Renderdoc. Nothing to install.

What risk level is list_textures? +

list_textures is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_textures? +

Yes. Add a rate_limit block to the list_textures 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_textures completely? +

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

list_textures is provided by the Renderdoc MCP server (linkingooo/renderdoc-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Renderdoc tool call.

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