CAPI Gateway MCP Server

CAPI is a lightweight API Gateway and load balancer built on Undertow's async proxy architecture. Services register themselves in HashiCorp Consul, and CAPI automatically discovers them, creates proxy handlers, and applies security, throttling, and observability policies - no database required.

People who need API integration tools inside Claude, Cursor, VS Code, or another MCP client. The project is written in Java.
