WHAT IT DOES

What adb_forward does on Ya Frida

AI agents invoke adb_forward to trigger actions in Ya Frida. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why adb_forward is rated High

Port forwarding creates a network tunnel between local and remote TCP ports. This is an active network configuration operation that triggers an external operation (ADB port forward rule) whose effects depend on the arguments provided. It is not purely reading data, nor is it destructive/financial, but it does execute a network configuration change that could expose services or enable further exploitation.

From the tool's definition Set up port forwarding (e.g. local='tcp:27042' remote='tcp:27042')

RECOMMENDED RULE

The rule that runs adb_forward safely

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

adb_forward Rate-limited

adb_forward stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about adb_forward

What does the adb_forward tool do? +

Set up port forwarding (e.g. local='tcp:27042' remote='tcp:27042'). It is categorised as a Execute tool in the Ya Frida MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on adb_forward? +

Register the Ya Frida MCP server in PolicyLayer and add a rule for adb_forward: 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 Ya Frida. Nothing to install.

What risk level is adb_forward? +

adb_forward is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit adb_forward? +

Yes. Add a rate_limit block to the adb_forward 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_forward completely? +

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

adb_forward is provided by the Ya Frida MCP server (1shin-7/ya-frida-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
