What list_tree does on Allcanuse
AI agents call list_tree to retrieve information from Allcanuse without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_tree is rated Low
Despite the empty description lowering confidence, the tool name strongly implies a directory listing or tree-viewing operation, which retrieves information without modifying data. The server context (system management tools) supports this interpretation. Classified as Read with low severity due to information disclosure risk being limited compared to command execution or data modification.
From the tool's definition Tool name 'list_tree' suggests listing/traversing a directory or file structure tree. No description provided, but the name pattern aligns with read-only operations like 'ls -R' or file tree traversal.
Attacks that exploit this kind of access
The rule that runs list_tree safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Allcanuse, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_tree, this is the rule to start with:
list_tree is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Allcanuse, apply this rule, and every list_tree call is checked against it from then on.
Questions about list_tree
list_tree is a read tool on the Allcanuse MCP server. It is categorised as a Read tool in the Allcanuse MCP Server, which means it retrieves data without modifying state.
Register the Allcanuse MCP server in PolicyLayer and add a rule for list_tree: 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 Allcanuse. Nothing to install.
list_tree 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_tree 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_tree. 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_tree is provided by the Allcanuse MCP server (ra1nyxin/allcanuse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
