AWS WAFV2 MCP Server Integration

AWS WAFV2, the Web Application Firewall version 2, is the advanced, regionalized iteration of Amazon Web Services' managed service designed to protect web applications and APIs from common web exploits and bots that may affect availability, compromise security, or consume excessive resources. Introduced in late 2019, this API version represents a significant evolution, introducing support for both regional and CloudFront (global) distributions within a single, unified management model. The core capabilities of AWS WAFV2 are articulated through a comprehensive set of endpoints that enable programmatic creation, configuration, and management of its foundational components. These include IP Sets for blocking or allowing traffic from specific addresses, Regex Pattern Sets for identifying malicious patterns in HTTP requests, and Rule Groups for creating reusable, custom rule collections. Central to the service is the Web ACL (Access Control List), a critical security container that holds a collection of rules and assigns a default action (Allow or Block) for requests that don't match any rule. Additional endpoints facilitate the association of a Web ACL with protected AWS resources like Application Load Balancers, Amazon API Gateway, Amazon CloudFront, and AWS AppSync. The API also supports granular logging configuration to services like Amazon Kinesis Data Firehose, detailed capacity checking for rule evaluation prior to deployment, and the creation of API keys for integrating third-party data sources into rules.
