List all available Lenny podcast episodes. Optionally filter by
AI agents call list_episodes to retrieve information from Lenny RAG 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 and enumerates existing podcast episode metadata without creating, modifying, deleting, or executing any operations. It is a pure read operation that queries a static catalog. The optional filtering is a read parameter, not a write or execution capability. Blast radius from misuse is minimal—an agent cannot cause harm by listing episodes.
From the tool's definition Tool name 'list_episodes' and function to 'list all available Lenny podcast episodes' with optional filtering indicates a retrieval-only operation with no side effects.

PolicyLayer is an MCP gateway — it sits between your AI agents and Lenny RAG MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_episodes:
{
"version": "1",
"default": "deny",
"tools": {
"list_episodes": {}
}
}list_episodes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
