List available HaldCLUT film simulation LUT files.
AI agents call list_luts to retrieve information from Rawtherapee without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists metadata about available LUT files in the RawTherapee environment. It has no side effects, does not modify data, and does not execute code or commands. It is purely informational, making it a Read category tool with low severity.
From the tool's definition Tool name 'list_luts' and description 'List available HaldCLUT film simulation LUT files' indicate a query/retrieval operation that enumerates available LUT files without modifying any data or triggering external operations.
Attacks that exploit this kind of access
List available HaldCLUT film simulation LUT files. It is categorised as a Read tool in the Rawtherapee MCP Server, which means it retrieves data without modifying state.
Register the Rawtherapee MCP server in PolicyLayer and add a rule for list_luts: 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 Rawtherapee. Nothing to install.
list_luts is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_luts 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.
Set action: deny in the PolicyLayer policy for list_luts. 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.
list_luts is provided by the Rawtherapee MCP server (lucamarien/rawtherapee-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
