AI agents call list-prompts to retrieve information from Dynamic MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries a list of prompts scoped to the current user. It performs no creation, modification, deletion, or execution. The read-only nature and informational purpose classify it as Read category with low severity, as listing prompts poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'list-prompts' and description 'List all available prompts for the current user' indicate a query/retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list-prompts gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Dynamic MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list-prompts:
{
"version": "1",
"default": "deny",
"tools": {
"list-prompts": {}
}
}list-prompts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List all available prompts for the current user. It is categorised as a Read tool in the Dynamic MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Dynamic MCP Server MCP server in PolicyLayer and add a rule for list-prompts: 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 Dynamic MCP Server. Nothing to install.
list-prompts 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-prompts 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-prompts. 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-prompts is provided by the Dynamic MCP Server MCP server (scitara-cto/dynamic-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Dynamic 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.
