List every document currently in the index, along with its word count.
AI agents call list_documents to retrieve information from MCP Demo - Document Search Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward read operation that retrieves metadata about indexed documents. It has no side effects, cannot modify data, and poses minimal risk even if called repeatedly or with unexpected arguments. The blast radius is limited to information disclosure of document inventory.
From the tool's definition Tool lists documents and their word counts from an index. No modification, deletion, or code execution occurs. Pure retrieval operation: 'List every document currently in the index.'

List every document currently in the index, along with its word count. It is categorised as a Read tool in the MCP Demo - Document Search Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Demo - Document Search Server MCP server in PolicyLayer and add a rule for list_documents: 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 Demo - Document Search Server. Nothing to install.
list_documents 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_documents 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_documents. 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_documents is provided by the MCP Demo - Document Search Server MCP server (simplifyaimm/mcp-demo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
