WHAT IT DOES

What adb_tunnel_list does on Deepadb

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

RISK

Why adb_tunnel_list is rated Low

This tool performs a read-only query of tunnel information with no side effects. It queries existing tunnel state without creating, modifying, deleting, or executing anything. The blast radius of misuse is minimal—an attacker gains visibility into tunnel configuration but cannot modify infrastructure or access restricted data beyond what tunnels are open.

From the tool's definition Tool name contains 'list' and description explicitly states 'List all active managed tunnels'. The operation retrieves and displays tunnel metadata (tunnel ID, device, direction, endpoints) without modifying any state.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs adb_tunnel_list safely

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

adb_tunnel_list Allowed

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

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

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

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

FAQ

Questions about adb_tunnel_list

What does the adb_tunnel_list tool do? +

List all active managed tunnels (opened via adb_tunnel_open). Shows tunnel ID, device, direction, and both endpoints. Note: this only surfaces tunnels created via adb_tunnel_open — tunnels created via the low-level adb_forward / adb_reverse won. It is categorised as a Read tool in the Deepadb MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on adb_tunnel_list? +

Register the Deepadb MCP server in PolicyLayer and add a rule for adb_tunnel_list: 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 Deepadb. Nothing to install.

What risk level is adb_tunnel_list? +

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

Can I rate-limit adb_tunnel_list? +

Yes. Add a rate_limit block to the adb_tunnel_list 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 adb_tunnel_list completely? +

Set action: deny in the PolicyLayer policy for adb_tunnel_list. 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 adb_tunnel_list? +

adb_tunnel_list is provided by the Deepadb MCP server (deepadb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
