list_prompts
AI agents call list_prompts to retrieve information from Prompt Store MCP 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 stored prompt data from a local SQLite database. It has no side effects—no data is created, modified, deleted, or executed. The blast radius of misuse is minimal; an AI agent could see all stored prompts but cannot harm them or perform external operations. Confidence is high despite the empty description because the tool name and server context leave no ambiguity.
From the tool's definition Tool name 'list_prompts' and context indicate data retrieval with no side effects. Server uses SQLite to store prompts; listing is a read-only operation.

list_prompts. It is categorised as a Read tool in the Prompt Store MCP MCP Server, which means it retrieves data without modifying state.
Register the Prompt Store 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 Prompt Store MCP. 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 Prompt Store MCP server (mhoshdev/prompt-store-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
