Get list of all documents in the knowledge base
AI agents call get_files to retrieve information from MCP Knowledge Base Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of existing documents without creating, modifying, deleting, or executing anything. It is a straightforward read operation with minimal risk—listing documents reveals metadata but does not alter state or expose sensitive content beyond what an authenticated user can already access.
From the tool's definition Tool name 'get_files' and description 'Get list of all documents in the knowledge base' indicate a retrieval operation with no side effects.

Get list of all documents in the knowledge base. It is categorised as a Read tool in the MCP Knowledge Base Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Knowledge Base Server MCP server in PolicyLayer and add a rule for get_files: 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 Knowledge Base Server. Nothing to install.
get_files 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 get_files 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 get_files. 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.
get_files is provided by the MCP Knowledge Base Server MCP server (maxsmosarski/mcp-knowledge-base). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
