AWS WAF MCP Server Integration
AWS WAF (Web Application Firewall) is a critical cloud security service provided by Amazon Web Services that enables developers to protect web applications and APIs from common web exploits and malicious traffic that could affect availability, compromise security, or consume excessive resources. As a managed service, it operates at the application layer (Layer 7) and integrates seamlessly with other AWS services such as Amazon CloudFront, Application Load Balancer, Amazon API Gateway, and AWS AppSync. The service's core capabilities involve creating and managing rules to filter and monitor HTTP/HTTPS requests. Developers can define custom rules using a combination of IP addresses, HTTP headers, HTTP body, URI strings, SQL injection patterns, and cross-site scripting patterns. Typical enterprise use cases include shielding a company's customer-facing e-commerce site from DDoS attacks and SQL injection, preventing credential stuffing by limiting request rates, and enforcing geo-restriction policies to comply with regional content licensing requirements. It serves as a frontline defense for any internet-facing workload hosted on AWS.
Technical Integration & Multi-Client Support
The AWS WAF MCP Integration translates REST paths, operational endpoints, and tool schemas into standardized Model Context Protocol JSON-RPC 2.0 messages. This allows AI assistants like Claude Desktop, Cursor IDE, VS Code (Cline/Roo Code), and Zed Editor to run tool queries and execute functions seamlessly.
Add stdio configuration block to claude_desktop_config.json.
Configure workspace root at .cursor/mcp.json or Settings -> MCP.
Insert server JSON payload into cline_mcp_settings.json.

DigitalOcean API MCP
The DigitalOcean API is a comprehensive, RESTful interface provided by DigitalOcean, a leading cloud infrastructure provider focused on simplifying cloud computing for developers, startups, and enterprises. It serves as the programmatic backbone for managing the entire DigitalOcean ecosystem, enabling users to provision, configure, and control cloud resources such as Droplets (virtual private servers), Kubernetes clusters, managed databases, networks, storage volumes, and application platforms. Core capabilities include full lifecycle management of these resources, from creation and scaling to monitoring and deletion, mirroring the functionality available in the DigitalOcean control panel. Its primary use cases range from automating infrastructure setup for CI/CD pipelines and enabling infrastructure-as-code practices to supporting dynamic application scaling and resource optimization for SaaS products, e-commerce sites, and development environments. The API is designed for both developers seeking to automate their cloud operations and businesses that require programmable, scalable cloud infrastructure without the complexity of larger hyperscale providers.
