Low Risk

cwa

Returns a list of Center Weather Advisories from a CWSU

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

AI agents call cwa to retrieve information from Zuplo 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 cwa 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 cwa tool do? +

Returns a list of Center Weather Advisories from a CWSU. It is categorised as a Read tool in the Zuplo MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on cwa? +

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

What risk level is cwa? +

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

Can I rate-limit cwa? +

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

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

cwa is provided by the Zuplo MCP server (emmanuel/test-ll8). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
