WHAT IT DOES

What start_homeassistant_tunnel does on Mcp Control Plane

AI agents invoke start_homeassistant_tunnel to trigger actions in Mcp Control Plane. 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 start_homeassistant_tunnel is rated High

While creating a network tunnel is technically a write-like operation that establishes a connection, the tool's purpose is to execute and maintain an active external operation (SSH tunneling).

From the tool's definition 'Start a persistent SSH tunnel' indicates the tool executes an external operation (SSH tunnel establishment) whose effects depend on runtime arguments and configuration. This triggers network connectivity and maintains persistent system-level connections.

RECOMMENDED RULE

The rule that runs start_homeassistant_tunnel safely

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

start_homeassistant_tunnel Rate-limited

start_homeassistant_tunnel 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.

Questions about start_homeassistant_tunnel

What does the start_homeassistant_tunnel tool do? +

Start a persistent SSH tunnel for Home Assistant: localhost -> Ubuntu localhost:8123. It is categorised as a Execute tool in the Mcp Control Plane MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on start_homeassistant_tunnel? +

Register the Mcp Control Plane MCP server in PolicyLayer and add a rule for start_homeassistant_tunnel: 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 Mcp Control Plane. Nothing to install.

What risk level is start_homeassistant_tunnel? +
