AI agents call get_folder to retrieve information from Filevine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about a folder using its ID as a lookup parameter. No data is created, modified, deleted, or used to trigger external operations. The action is a simple read query typical of case management system navigation. In the context of Filevine (legal case management), accessing folder information poses minimal risk—it is informational only.
From the tool's definition Tool name 'get_folder' and description 'Get a folder by ID' indicate retrieval of folder metadata or contents without modification.
Attacks that exploit this kind of access
Get a folder by ID. It is categorised as a Read tool in the Filevine MCP Server, which means it retrieves data without modifying state.
Register the Filevine MCP server in PolicyLayer and add a rule for get_folder: 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 Filevine. Nothing to install.
get_folder 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_folder 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_folder. 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_folder is provided by the Filevine MCP server (rosenadvertising/filevine-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
