WHAT IT DOES

What tree does on Http

AI agents call tree to retrieve information from Http without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why tree is rated Low

This tool performs information retrieval only—it queries and displays the structure of project dependencies without creating, modifying, deleting, or executing any code. The action is non-destructive and has no side effects. This is a typical read operation commonly found in package management and build system tools.

From the tool's definition Tool name 'tree' and description 'Displays the dependency tree for a Rust project' indicates a read-only operation that retrieves and presents project dependency information without modifying any data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs tree safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Http, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For tree, this is the rule to start with:

tree Allowed

tree is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "tree": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Http, apply this rule, and every tree call is checked against it from then on.

FAQ

Questions about tree

What does the tree tool do? +

Displays the dependency tree for a Rust project. It is categorised as a Read tool in the Http MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on tree? +

Register the Http MCP server in PolicyLayer and add a rule for 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 Http. Nothing to install.

What risk level is tree? +

tree is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit tree? +

Yes. Add a rate_limit block to the 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.

How do I block tree completely? +

Set action: deny in the PolicyLayer policy for 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.

What MCP server provides tree? +

tree is provided by the Http MCP server (@paretools/http). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
