Список папок (viewfolder) в файле: путь, число прямых view и view в поддереве.
AI agents call list_folders to retrieve information from Navisworks Viewpoints without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and retrieves information about folder structure and view hierarchies within Navisworks viewpoint files. It performs introspection/enumeration without creating, modifying, deleting, or executing operations. This is a pure Read category risk with low severity since it only exposes structural metadata.
From the tool's definition Tool name 'list_folders' and description indicating it lists (Список папок) folders with metadata (path, direct view count, subtree view count) — a retrieval operation with no side effects.
Attacks that exploit this kind of access
Список папок (viewfolder) в файле: путь, число прямых view и view в поддереве. It is categorised as a Read tool in the Navisworks Viewpoints MCP Server, which means it retrieves data without modifying state.
Register the Navisworks Viewpoints MCP server in PolicyLayer and add a rule for list_folders: 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 Navisworks Viewpoints. Nothing to install.
list_folders 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_folders 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_folders. 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_folders is provided by the Navisworks Viewpoints MCP server (mikhalchankasm/navisworks-viewpoints-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
