Low Risk

host

The QNAP NAS URL (e.g., `http://10.1.1.241:8080`).

Part of the Server Qnap MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call host to retrieve information from Server Qnap without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though host only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the host tool do? +

The QNAP NAS URL (e.g., `http://10.1.1.241:8080`).. It is categorised as a Read tool in the Server Qnap MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on host? +

Add a rule in your Intercept YAML policy under the tools section for host. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Server Qnap MCP server.

What risk level is host? +

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

Can I rate-limit host? +

Yes. Add a rate_limit block to the host rule in your Intercept 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 host completely? +

Set action: deny in the Intercept policy for host. 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 host? +

host is provided by the Server Qnap MCP server (@marcelo-ochoa/server-qnap). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
