AWS WAF Rules & Rate Limiting Calculator

AWS WAF Rules & Rate Limiting Calculator MCP Connector for Claude

A+

Calculate AWS WAF capacity, rate limits, and rule complexity against best practices.

3 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides deterministic calculations for AWS WAF (Web Application Firewall) configurations. It helps architects and security engineers validate their rule sets against AWS recommended limits and mandatory constraints. Use calculate_waf_capacity to determine total rule counts across Web ACLs and rule groups, analyze_rate_limiting to verify rate-based rule thresholds, and evaluate_rule_complexity to ensure nesting depth and condition counts stay within safe operational bounds.

3 tools expose this connector's capabilities to your AI agent.

analyze_rate_limiting

Evaluates rate-based rule configurations against AWS minimum requirements and constraints

calculate_waf_capacity

Calculates the total rule and resource capacity based on the number of Web ACLs and rule groups provided

evaluate_rule_complexity

Checks if the logical structure of rules adheres to nesting and condition limits

Calculate capacity for 5 Web ACLs with 50 rules each, and 10 rule groups with 20 rules each.

Total Web ACLs: 5. Total rules in ACLs: 250. Total rule groups: 10. Total rules in groups: 200.

Is a rate threshold of 50 requests per 5 minutes valid?

No, the threshold is invalid because it is below the minimum requirement of 100 requests.

Check complexity for a rule with 6 levels of nesting and 12 conditions.

The configuration is invalid. It violates the nesting limit (max 5) and exceeds the recommended condition limit (max 10).

You can use the `calculate_waf_capacity` tool. It will return a list of capacity warnings if your planned number of rules or Web ACLs exceeds the recommended limits.
