FoxAgent

FoxAgent is a VFP instance orchestration system that allows AI assistants like Claude Desktop and OpenCode to inspect and control Visual FoxPro applications in real-time. VFP agents register with a central Broker and expose inspection capabilities (variables, cursors, forms) and execution capabilities (commands, custom tools) via a Named Pipe-based protocol.

Architecture

FoxAgent consists of three components: the Broker (central server in .NET 10), the Bridge (COM DLL in .NET 4.8 that connects VFP to the Broker) and the McpHost (MCP server for AI agents). The Broker maintains a registry of connected VFP instances and exposes an HTTP API for discovery. Each instance has a dedicated inspection Named Pipe for bidirectional communication.
