# Tool Filter MCP

> Use this tool when you need to restrict access to specific tools from upstream MCP servers, as it filters tools via a regex-based deny list, solving issues related to unauthorized tool usage and improving system security. It takes in tool requests as input and outputs filtered tool access, providing a secure interface for MCP server management. Ideal for use cases where access control and tool restriction are necessary.
