THE RISK

Why get_dependency_tree needs a policy

This tool retrieves and displays dependency metadata for a Maven artifact. It queries existing data without modifying, deleting, or executing any code. The operation has no side effects and poses minimal security risk to the system.

From the tool's definition Tool name 'get_dependency_tree' and description 'Get complete dependency tree for an artifact' indicate retrieval of dependency information from the local Maven repository. The verb 'Get' and context of analyzing jar files confirms this is a query operation.

POLICY

How to control get_dependency_tree

PolicyLayer is an MCP gateway — it sits between your AI agents and Maven Decoder MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_dependency_tree:

policy.json

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

get_dependency_tree is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Maven Decoder MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
