AI agents call kobold_sd_samplers to retrieve information from Kobold MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple enumeration/listing of available options, which is a read-only operation with no side effects. It provides metadata about samplers but does not execute image generation, modify configurations, or perform any destructive operations. The blast radius of misuse is negligible.
From the tool's definition Tool name 'kobold_sd_samplers' and description 'List available Stable Diffusion samplers' indicate a query operation that retrieves information about available samplers without modifying state or triggering generation.
Documented attack patterns abuse exactly the kind of access kobold_sd_samplers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Kobold MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for kobold_sd_samplers:
{
"version": "1",
"default": "deny",
"tools": {
"kobold_sd_samplers": {}
}
}kobold_sd_samplers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List available Stable Diffusion samplers. It is categorised as a Read tool in the Kobold MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kobold MCP Server MCP server in PolicyLayer and add a rule for kobold_sd_samplers: 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 Kobold MCP Server. Nothing to install.
kobold_sd_samplers 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 kobold_sd_samplers 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 kobold_sd_samplers. 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.
kobold_sd_samplers is provided by the Kobold MCP Server MCP server (phialsbasement/koboldcpp-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Kobold MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
