AI agents call docs_list_docs to retrieve information from McpDocServer 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 documentation without modifying, executing, or deleting anything. While the description is empty, the naming convention and server context strongly suggest a simple listing operation.
From the tool's definition Tool name 'docs_list_docs' indicates listing/enumeration of documentation. Server description emphasizes 'document crawling, local document loading, keyword searching, and document detail retrieval' — all read-only operations.

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