Low Risk

scan_waf_coverage

Run WAF Coverage security scanner only. Read-only. Does not modify any AWS resources.

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

AI agents call scan_waf_coverage to retrieve information from Aws Security 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 scan_waf_coverage 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 scan_waf_coverage tool do? +

Run WAF Coverage security scanner only. Read-only. Does not modify any AWS resources.. It is categorised as a Read tool in the Aws Security MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on scan_waf_coverage? +

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

What risk level is scan_waf_coverage? +

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

Can I rate-limit scan_waf_coverage? +

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

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

scan_waf_coverage is provided by the Aws Security MCP server (aws-security-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
