AI agents call list_slash_commands to retrieve information from MCP Prompts Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays available commands without modifying, executing, or deleting any data. It is a non-destructive informational query, fitting the Read category with low severity since misuse poses no operational or security risk beyond information disclosure of command names.
From the tool's definition Tool name 'list_slash_commands' and description 'List available slash commands' indicate a query/retrieval operation with no side effects. Returns enumerated data only.
Documented attack patterns abuse exactly the kind of access list_slash_commands gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Prompts Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_slash_commands:
{
"version": "1",
"default": "deny",
"tools": {
"list_slash_commands": {}
}
}list_slash_commands is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List available slash commands. It is categorised as a Read tool in the MCP Prompts Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Prompts Server MCP server in PolicyLayer and add a rule for list_slash_commands: 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 MCP Prompts Server. Nothing to install.
list_slash_commands 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_slash_commands 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_slash_commands. 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_slash_commands is provided by the MCP Prompts Server MCP server (sparesparrow/mcp-prompts). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
